Tog ath-chòmhdach co-theacsail gus liostaichean de cheanglaichean agus barrachd a thaisbeanadh leis a’ plugan tuiteam-sìos Bootstrap.

Ro-shealladh

Tha dropdowns nan ath-chòmhdach co-theacsail toggle airson liostaichean de cheanglaichean agus barrachd a thaisbeanadh. Tha iad air an dèanamh eadar-ghnìomhach leis a’ plugan Bootstrap tuiteam-sìos JavaScript. Tha iad air an togail le cliogadh, chan ann le hovering; is e co-dhùnadh dealbhaidh a tha seo a dh’aona ghnothach .

Tha dropdowns air an togail air leabharlann treas pàrtaidh, Popper , a bheir seachad suidheachadh fiùghantach agus lorg sealladh. Dèan cinnteach gun cuir thu a-steach popper.min.js ro JavaScript Bootstrap no cleachd bootstrap.bundle.min.js/ bootstrap.bundle.jsanns a bheil Popper. Cha bhith Popper air a chleachdadh airson dropdowns a shuidheachadh ann am bàraichean seòlaidh ged nach eil feum air suidheachadh fiùghantach.

Ma tha thu a’ togail ar JavaScript bhon tùs, feumaidhutil.js e .

Ruigsinneachd

Tha inbhe WAI ARIA a’ mìneachadh fìor role="menu"widget , ach tha seo sònraichte do chlàran-bìdh coltach ri tagradh a bhrosnaicheas gnìomhan no gnìomhan. Chan fhaod a bhith ann an clàir-bìdh ARIA ach nithean clàr, nithean clàr bogsa-seic, nithean clàr putan rèidio, buidhnean putan rèidio, agus fo-chlàran.

Air an làimh eile, tha dropdowns Bootstrap air an dealbhadh gus a bhith coitcheann agus iomchaidh airson grunn shuidheachaidhean agus structaran comharrachaidh. Mar eisimpleir, tha e comasach dropdowns a chruthachadh anns a bheil cuir a-steach a bharrachd agus smachdan foirm, leithid raointean sgrùdaidh no foirmean logadh a-steach. Air an adhbhar seo, chan eil Bootstrap a’ dùileachadh (no a’ cur ris gu fèin-ghluasadach) gin de na roleagus na aria-buadhan a tha riatanach airson fìor chlàran ARIA . Feumaidh ùghdaran na buadhan nas sònraichte sin a ghabhail a-steach iad fhèin.

Ach, bidh Bootstrap a’ cur taic a-staigh airson a’ mhòr-chuid de eadar-obrachaidhean clàr meur-chlàr àbhaisteach, leithid an comas gluasad tro .dropdown-itemeileamaidean fa leth a’ cleachdadh iuchraichean a’ chursair agus an clàr a dhùnadh leis an ESCiuchair.

Eisimpleirean

Còmhdaich tog an tuiteam-sìos (am putan no an ceangal agad) agus an clàr a-nuas taobh a-staigh .dropdown, no eileamaid eile a dhearbhas position: relative;. Faodar dropdowns a bhrosnachadh bho <a>no <button>eileamaidean a fhreagras air na feumalachdan a dh’ fhaodadh a bhith agad.

Putan singilte

Faodar singilte sam bith .btna thionndadh gu bhith na tog sìos le beagan atharrachaidhean comharrachaidh. Seo mar as urrainn dhut an cur gu obair le gach <button>eileamaid:

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" data-toggle="dropdown" aria-expanded="false">
    Dropdown button
  </button>
  <div class="dropdown-menu">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
  </div>
</div>

Agus le <a>eileamaidean:

<div class="dropdown">
  <a class="btn btn-secondary dropdown-toggle" href="#" role="button" data-toggle="dropdown" aria-expanded="false">
    Dropdown link
  </a>

  <div class="dropdown-menu">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
  </div>
</div>

Is e am pàirt as fheàrr gun urrainn dhut seo a dhèanamh le tionndadh putan sam bith, cuideachd:

<!-- Example single danger button -->
<div class="btn-group">
  <button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
    Action
  </button>
  <div class="dropdown-menu">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
    <div class="dropdown-divider"></div>
    <a class="dropdown-item" href="#">Separated link</a>
  </div>
</div>

Putan sgoltadh

San aon dòigh, cruthaich dropdowns putan sgoltadh le cha mhòr an aon chomharra ri tuiteam sìos putan singilte, ach le bhith a’ cur a-steach .dropdown-toggle-splitfarsaingeachd cheart timcheall air a ’chùram tuiteam-sìos.

Bidh sinn a’ cleachdadh a’ chlas a bharrachd seo gus a’ chòmhnard paddingair gach taobh den chùram a lughdachadh 25% agus thoir air falbh an margin-leftfheadhainn a tha air a chur ris airson putanan sìos gu cunbhalach. Bidh na h-atharrachaidhean a bharrachd sin a’ cumail a’ chùram sa mheadhan anns a’ phutan sgoltadh agus a’ toirt seachad àite bualaidh nas freagarraiche ri taobh a’ phrìomh phutan.

<!-- Example split danger button -->
<div class="btn-group">
  <button type="button" class="btn btn-danger">Action</button>
  <button type="button" class="btn btn-danger dropdown-toggle dropdown-toggle-split" data-toggle="dropdown" aria-expanded="false">
    <span class="sr-only">Toggle Dropdown</span>
  </button>
  <div class="dropdown-menu">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
    <div class="dropdown-divider"></div>
    <a class="dropdown-item" href="#">Separated link</a>
  </div>
</div>

Gu gnàthach, tha clàr tuiteam-sìos air a shuidheachadh gu fèin-ghluasadach 100% bhon mhullach agus air taobh clì a phàrant. Cuir .dropdown-menu-rightri a .dropdown-menugu deas co-thaobhadh ris a’ chlàr tuiteam-sìos.

Cinn suas! Tha dropdowns air an suidheachadh le taing dha Popper (ach a-mhàin nuair a tha iad ann am bàr seòlaidh).

<div class="btn-group">
  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">

Cleachdadh

Tro bhuadhan dàta no JavaScript, bidh am plugan tuiteam-sìos a’ togail susbaint falaichte (clàran-taice sìos) le bhith a’ togail a’ .showchlas air a’ phàrant .dropdown-menu. Thathas data-toggle="dropdown"an urra ris a’ fheart airson clàran-bìdh a dhùnadh sìos aig ìre tagraidh, agus mar sin is e deagh bheachd a th’ ann a chleachdadh an-còmhnaidh.

On touch-enabled devices, opening a dropdown adds empty ( $.noop) mouseover handlers to the immediate children of the <body> element. This admittedly ugly hack is necessary to work around a quirk in iOS’ event delegation, which would otherwise prevent a tap anywhere outside of the dropdown from triggering the code that closes the dropdown. Once the dropdown is closed, these additional empty mouseover handlers are removed.

Via data attributes

Add data-toggle="dropdown" to a link or button to toggle a dropdown.

<div class="dropdown">
  <button type="button" data-toggle="dropdown" aria-expanded="false">
    Dropdown trigger
  </button>
  <div class="dropdown-menu">
    ...
  </div>
</div>

Via JavaScript

Call the dropdowns via JavaScript:

$('.dropdown-toggle').dropdown()

`data-toggle="dropdown"` still required

Regardless of whether you call your dropdown via JavaScript or instead use the data-api, data-toggle="dropdown" is always required to be present on the dropdown’s trigger element.

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset="".

Name	Type	Default	Description
offset	number \| string \| function	0	Offset of the dropdown relative to its target. When a function is used to determine the offset, it is called with an object containing the offset data as its first argument. The function must return an object with the same structure. The triggering element DOM node is passed as the second argument. For more information refer to Popper's offset docs.
flip	boolean	true	Allow Dropdown to flip in case of an overlapping on the reference element. For more information refer to Popper's flip docs.
boundary	string \| element	'scrollParent'	Overflow constraint boundary of the dropdown menu. Accepts the values of `'viewport'`, `'window'`, `'scrollParent'`, or an HTMLElement reference (JavaScript only). For more information refer to Popper's preventOverflow docs.
reference	string \| element	'toggle'	Reference element of the dropdown menu. Accepts the values of `'toggle'`, `'parent'`, or an HTMLElement reference. For more information refer to Popper's referenceObject docs.
display	string	'dynamic'	By default, we use Popper for dynamic positioning. Disable this with `static`.
popperConfig	null \| object	null	To change Bootstrap's default Popper config, see Popper's configuration

Note when boundary is set to any value other than 'scrollParent', the style position: static is applied to the .dropdown container.

Methods

Method	Description
`$().dropdown('toggle')`	Toggles the dropdown menu of a given navbar or tabbed navigation.
`$().dropdown('show')`	Shows the dropdown menu of a given navbar or tabbed navigation.
`$().dropdown('hide')`	Hides the dropdown menu of a given navbar or tabbed navigation.
`$().dropdown('update')`	Updates the position of an element’s dropdown.
`$().dropdown('dispose')`	Destroys an element’s dropdown.

Events

All dropdown events are fired at the .dropdown-menu’s parent element and have a relatedTarget property, whose value is the toggling anchor element. hide.bs.dropdown and hidden.bs.dropdown events have a clickEvent property (only when the original event type is click) that contains an Event Object for the click event.

Event	Description
`show.bs.dropdown`	This event fires immediately when the show instance method is called.
`shown.bs.dropdown`	Thèid an tachartas seo a losgadh nuair a bhios an tuiteam-sìos ri fhaicinn don neach-cleachdaidh (feitheamh ri eadar-ghluasadan CSS, gus a chrìochnachadh).
`hide.bs.dropdown`	Thèid an tachartas seo a losgadh sa bhad nuair a thèid an dòigh seiche seiche a ghairm.
`hidden.bs.dropdown`	Thèid an tachartas seo a losgadh nuair a tha an tuiteam-sìos deiseil a bhith falaichte bhon neach-cleachdaidh (feitheamh ri eadar-ghluasadan CSS, gus a chrìochnachadh).

$('#myDropdown').on('show.bs.dropdown', function () {
  // do something...
