Lys groep

Lysgroepe is 'n buigsame en kragtige komponent om 'n reeks inhoud te vertoon. Verander en brei dit uit om omtrent enige inhoud binne te ondersteun.

Basiese voorbeeld

Die mees basiese lysgroep is 'n ongeordende lys met lysitems en die regte klasse. Bou daarop met die opsies wat volg, of met jou eie CSS soos nodig.

N item
'n Tweede item
'n Derde item
'n Vierde item
En 'n vyfde een

<ul class="list-group">
  <li class="list-group-item">An item</li>
  <li class="list-group-item">A second item</li>
  <li class="list-group-item">A third item</li>
  <li class="list-group-item">A fourth item</li>
  <li class="list-group-item">And a fifth one</li>
</ul>

Aktiewe items

Voeg .activeby 'n .list-group-itemom die huidige aktiewe keuse aan te dui.

'n Aktiewe item
A second item
A third item
A fourth item
And a fifth one

<ul class="list-group">
  <li class="list-group-item active" aria-current="true">An active item</li>
  <li class="list-group-item">A second item</li>
  <li class="list-group-item">A third item</li>
  <li class="list-group-item">A fourth item</li>
  <li class="list-group-item">And a fifth one</li>
</ul>

Gedeaktiveerde items

Voeg .disabledby 'n .list-group-itemom dit gedeaktiveer te laat lyk . Let daarop dat sommige elemente met .disabledook gepasmaakte JavaScript sal vereis om hul klikgebeurtenisse (bv. skakels) ten volle te deaktiveer.

'n Gestremde item
A second item
A third item
A fourth item
And a fifth one

<ul class="list-group">
  <li class="list-group-item disabled" aria-disabled="true">A disabled item</li>
  <li class="list-group-item">A second item</li>
  <li class="list-group-item">A third item</li>
  <li class="list-group-item">A fourth item</li>
  <li class="list-group-item">And a fifth one</li>
</ul>

Skakels en knoppies

Gebruik <a>s of <button>s om uitvoerbare lys groepitems te skep met sweef, gedeaktiveerde en aktiewe toestande deur by te voeg .list-group-item-action. Ons skei hierdie pseudo-klasse om te verseker dat lysgroepe wat van nie-interaktiewe elemente (soos <li>e of <div>s) gemaak is, nie 'n klik of tik bekostigbaarheid bied nie.

Maak seker dat jy nie die standaard .btnklasse hier gebruik nie .

Die huidige skakelitem 'n Tweede skakelitem 'n Derde skakelitem 'n Vierde skakelitem 'n Gedeaktiveerde skakelitem

<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action active" aria-current="true">
    The current link item
  </a>
  <a href="#" class="list-group-item list-group-item-action">A second link item</a>
  <a href="#" class="list-group-item list-group-item-action">A third link item</a>
  <a href="#" class="list-group-item list-group-item-action">A fourth link item</a>
  <a class="list-group-item list-group-item-action disabled">A disabled link item</a>
</div>

Met <button>s kan jy ook gebruik maak van die disabledkenmerk in plaas van die .disabledklas. Ongelukkig <a>ondersteun s nie die gestremde kenmerk nie.

<div class="list-group">
  <button type="button" class="list-group-item list-group-item-action active" aria-current="true">
    The current button
  </button>
  <button type="button" class="list-group-item list-group-item-action">A second item</button>
  <button type="button" class="list-group-item list-group-item-action">A third button item</button>
  <button type="button" class="list-group-item list-group-item-action">A fourth button item</button>
  <button type="button" class="list-group-item list-group-item-action" disabled>A disabled button item</button>
</div>

Spoel

Voeg .list-group-flushby om sommige grense en afgeronde hoeke te verwyder om lysgroepitems rand-tot-rand in 'n ouerhouer (bv. kaarte) weer te gee.

N item
'n Tweede item
'n Derde item
'n Vierde item
En 'n vyfde een

<ul class="list-group list-group-flush">
  <li class="list-group-item">An item</li>
  <li class="list-group-item">A second item</li>
  <li class="list-group-item">A third item</li>
  <li class="list-group-item">A fourth item</li>
  <li class="list-group-item">And a fifth one</li>
</ul>

Genommer

Voeg die .list-group-numberedwysigerklas by (en gebruik opsioneel 'n <ol>element) om in te teken op genommerde lysgroepitems. Getalle word gegenereer via CSS (in teenstelling met 'n <ol>se verstekblaaierstilering) vir beter plasing binne lysgroepitems en om beter aanpassing moontlik te maak.

Getalle word gegenereer deur counter-resetop die <ol>, en dan gestileer en geplaas met 'n ::beforepseudo-element op die <li>met counter-incrementen content.

  <li class="list-group-item">A list item</li>

Dit werk ook uitstekend met persoonlike inhoud.

</ol>

Horisontaal

Voeg .list-group-horizontalby om die uitleg van lysgroepitems van vertikaal na horisontaal oor alle breekpunte te verander. Alternatiewelik, kies 'n responsiewe variant .list-group-horizontal-{sm|md|lg|xl|xxl}om 'n lysgroep horisontaal te maak wat by daardie breekpunt begin min-width. Tans kan horisontale lysgroepe nie met spoellysgroepe gekombineer word nie.

ProTip: Wil jy groepitems met gelyke breedte lys hê wanneer dit horisontaal is? Voeg .flex-fillby elke lys groep item.

Kontekstuele klasse

Gebruik kontekstuele klasse om lysitems met 'n statige agtergrond en kleur te styl.

'n Eenvoudige verstek lys groep item
'n Eenvoudige primêre lys groep item
'n Eenvoudige sekondêre lys groep item
'n Eenvoudige sukseslysgroepitem
'n Eenvoudige gevaarlysgroepitem
'N Eenvoudige waarskuwing lys groep item
'N Eenvoudige inligting lys groep item
'n Eenvoudige ligte lys groep item
'N Eenvoudige donker lys groep item

<ul class="list-group">
  <li class="list-group-item">A simple default list group item</li>

  <li class="list-group-item list-group-item-primary">A simple primary list group item</li>
  <li class="list-group-item list-group-item-secondary">A simple secondary list group item</li>
  <li class="list-group-item list-group-item-success">A simple success list group item</li>
  <li class="list-group-item list-group-item-danger">A simple danger list group item</li>
  <li class="list-group-item list-group-item-warning">A simple warning list group item</li>
  <li class="list-group-item list-group-item-info">A simple info list group item</li>
  <li class="list-group-item list-group-item-light">A simple light list group item</li>
  <li class="list-group-item list-group-item-dark">A simple dark list group item</li>
</ul>

Kontekstuele klasse werk ook met .list-group-item-action. Let op die byvoeging van die sweefstyle wat hier nie in die vorige voorbeeld voorkom nie. Die staat word ook ondersteun .active; pas dit toe om 'n aktiewe seleksie op 'n kontekstuele lysgroepitem aan te dui.

Dra betekenis aan ondersteunende tegnologieë oor

Die gebruik van kleur om betekenis toe te voeg, verskaf slegs 'n visuele aanduiding, wat nie aan gebruikers van ondersteunende tegnologieë – soos skermlesers – oorgedra sal word nie. Maak seker dat inligting wat deur die kleur aangedui word óf duidelik uit die inhoud self (bv. die sigbare teks), óf op alternatiewe wyse ingesluit word, soos bykomende teks wat by die .visually-hiddenklas versteek is.

Met kentekens

Voeg kentekens by enige lysgroepitem om ongeleesde tellings, aktiwiteit en meer te wys met behulp van sommige nutsprogramme .

</ul>

Pasgemaakte inhoud

Voeg byna enige HTML binne, selfs vir gekoppelde lysgroepe soos die een hieronder, met behulp van flexbox-nutsprogramme .

Merkblokkies en radio's

Plaas Bootstrap se merkblokkies en radio's binne lys groepitems en pasmaak soos nodig. Jy kan hulle sonder <label>s gebruik, maar onthou asseblief om 'n aria-labelkenmerk en waarde vir toeganklikheid in te sluit.

<ul class="list-group">
  <li class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="" aria-label="...">
    First checkbox
  </li>
  <li class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="" aria-label="...">
    Second checkbox
  </li>
  <li class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="" aria-label="...">
    Third checkbox
  </li>
  <li class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="" aria-label="...">
    Fourth checkbox
  </li>
  <li class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="" aria-label="...">
    Fifth checkbox
  </li>
</ul>

En as jy <label>s wil hê as die .list-group-itemvir groot trefareas, kan jy dit ook doen.

<div class="list-group">
  <label class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="">
    First checkbox
  </label>
  <label class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="">
    Second checkbox
  </label>
  <label class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="">
    Third checkbox
  </label>
  <label class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="">
    Fourth checkbox
  </label>
  <label class="list-group-item">
    <input class="form-check-input me-1" type="checkbox" value="">
    Fifth checkbox
  </label>
</div>

Mengsels

Gebruik in kombinasie met $theme-colorsom die kontekstuele variantklasse vir .list-group-items te genereer.

@mixin list-group-item-variant($state, $background, $color) {
  .list-group-item-#{$state} {
    color: $color;
    background-color: $background;

    &.list-group-item-action {
      &:hover,
      &:focus {
        color: $color;
        background-color: shade-color($background, 10%);
      }

      &.active {
        color: $white;
        background-color: $color;
        border-color: $color;
      }
    }
  }
}

Lus

Lus wat die wysigerklasse genereer met die list-group-item-variant()mixin.

// List group contextual variants
//
// Add modifier classes to change text and background color on individual items.
// Organizationally, this must come after the `:hover` states.

@each $state, $value in $theme-colors {
  $list-group-variant-bg: shift-color($value, $list-group-item-bg-scale);
  $list-group-variant-color: shift-color($value, $list-group-item-color-scale);
  @if (contrast-ratio($list-group-variant-bg, $list-group-variant-color) < $min-contrast-ratio) {

}

JavaScript gedrag

Gebruik die oortjie JavaScript-inprop—sluit dit individueel of deur die saamgestelde bootstrap.jslêer in—om ons lysgroep uit te brei om oortjies van plaaslike inhoud te skep.

Tuis Profiel Boodskappe Instellings

Sommige plekhouer-inhoud in 'n paragraaf wat met "Tuis" verband hou. En nog 'n bietjie inhoud, wat hier net gebruik word om hierdie oortjiepaneel uit te vul en te vul. In produksie sou jy natuurlik meer werklike inhoud hier hê. En nie net teks nie. Dit kan enigiets wees, regtig. Teks, beelde, vorms.

Some placeholder content in a paragraph relating to "Profile". And some more content, used here just to pad out and fill this tab panel. In production, you would obviously have more real content here. And not just text. It could be anything, really. Text, images, forms.

Some placeholder content in a paragraph relating to "Messages". And some more content, used here just to pad out and fill this tab panel. In production, you would obviously have more real content here. And not just text. It could be anything, really. Text, images, forms.

Some placeholder content in a paragraph relating to "Settings". And some more content, used here just to pad out and fill this tab panel. In production, you would obviously have more real content here. And not just text. It could be anything, really. Text, images, forms.

    </div>
  </div>
</div>

Die gebruik van data-kenmerke

Jy kan 'n lysgroepnavigasie aktiveer sonder om enige JavaScript te skryf deur bloot 'n element te spesifiseer data-bs-toggle="list"of op 'n element. Gebruik hierdie data-kenmerke op .list-group-item.

<div role="tabpanel">
  <!-- List group -->
  <div class="list-group" id="myList" role="tablist">
    <a class="list-group-item list-group-item-action active" data-bs-toggle="list" href="#home" role="tab">Home</a>
    <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#profile" role="tab">Profile</a>
    <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#messages" role="tab">Messages</a>
    <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#settings" role="tab">Settings</a>
  </div>

  <!-- Tab panes -->
  <div class="tab-content">
    <div class="tab-pane active" id="home" role="tabpanel">...</div>
    <div class="tab-pane" id="profile" role="tabpanel">...</div>
    <div class="tab-pane" id="messages" role="tabpanel">...</div>
    <div class="tab-pane" id="settings" role="tabpanel">...</div>
  </div>
</div>

Via JavaScript

Aktiveer tabbare lysitem via JavaScript (elke lysitem moet individueel geaktiveer word):

var triggerTabList = [].slice.call(document.querySelectorAll('#myTab a'))
triggerTabList.forEach(function (triggerEl) {
  var tabTrigger = new bootstrap.Tab(triggerEl)

  triggerEl.addEventListener('click', function (event) {
    event.preventDefault()
    tabTrigger.show()
  })
})

Jy kan individuele lysitem op verskeie maniere aktiveer:

var triggerEl = document.querySelector('#myTab a[href="#profile"]')
bootstrap.Tab.getInstance(triggerEl).show() // Select tab by name

var triggerFirstTabEl = document.querySelector('#myTab li:first-child a')
bootstrap.Tab.getInstance(triggerFirstTabEl).show() // Select first tab

Vervaag effek

To make tabs panel fade in, add .fade to each .tab-pane. The first tab pane must also have .show to make the initial content visible.

<div class="tab-content">
  <div class="tab-pane fade show active" id="home" role="tabpanel">...</div>
  <div class="tab-pane fade" id="profile" role="tabpanel">...</div>
  <div class="tab-pane fade" id="messages" role="tabpanel">...</div>
  <div class="tab-pane fade" id="settings" role="tabpanel">...</div>
</div>

Methods

constructor

Activates a list item element and content container. Tab should have either a data-bs-target or an href targeting a container node in the DOM.

  <a class="list-group-item list-group-item-action active" data-bs-toggle="list" href="#home" role="tab">Home</a>
  <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#profile" role="tab">Profile</a>
  <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#messages" role="tab">Messages</a>
  <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#settings" role="tab">Settings</a>
</div>

<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel">...</div>
  <div class="tab-pane" id="profile" role="tabpanel">...</div>
  <div class="tab-pane" id="messages" role="tabpanel">...</div>
  <div class="tab-pane" id="settings" role="tabpanel">...</div>
</div>

<script>
  var firstTabEl = document.querySelector('#myTab a:last-child')
  var firstTab = new bootstrap.Tab(firstTabEl)

  firstTab.show()
</script>

show

Selects the given list item and shows its associated pane. Any other list item that was previously selected becomes unselected and its associated pane is hidden. Returns to the caller before the tab pane has actually been shown (for example, before the shown.bs.tab event occurs).

  var someListItemEl = document.querySelector('#someListItem')
  var tab = new bootstrap.Tab(someListItemEl)

  tab.show()

dispose

Destroys an element’s tab.

getInstance

Static method which allows you to get the tab instance associated with a DOM element

var triggerEl = document.querySelector('#trigger')
var tab = bootstrap.Tab.getInstance(triggerEl) // Returns a Bootstrap tab instance

getOrCreateInstance

Static method which allows you to get the tab instance associated with a DOM element, or create a new one in case it wasn’t initialized

var triggerEl = document.querySelector('#trigger')
var tab = bootstrap.Tab.getOrCreateInstance(triggerEl) // Returns a Bootstrap tab instance

Events

When showing a new tab, the events fire in the following order:

hide.bs.tab (on the current active tab)
show.bs.tab (on the to-be-shown tab)
hidden.bs.tab (on the previous active tab, the same one as for the hide.bs.tab event)
shown.bs.tab (on the newly-active just-shown tab, the same one as for the show.bs.tab event)

If no tab was already active, the hide.bs.tab and hidden.bs.tab events will not be fired.

Event type	Description
`show.bs.tab`	This event fires on tab show, but before the new tab has been shown. Use `event.target` and `event.relatedTarget` to target the active tab and the previous active tab (if available) respectively.
`shown.bs.tab`	This event fires on tab show after a tab has been shown. Use `event.target` and `event.relatedTarget` to target the active tab and the previous active tab (if available) respectively.
`hide.bs.tab`	This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use `event.target` and `event.relatedTarget` to target the current active tab and the new soon-to-be-active tab, respectively.
`hidden.bs.tab`	This event fires after a new tab is shown (and thus the previous active tab is hidden). Use `event.target` and `event.relatedTarget` to target the previous active tab and the new active tab, respectively.

var tabElms = document.querySelectorAll('a[data-bs-toggle="list"]')
tabElms.forEach(function(tabElm) {
  tabElm.addEventListener('shown.bs.tab', function (event) {
    event.target // newly activated tab
    event.relatedTarget // previous active tab
  })
}
