Okwehliswayo

Guqula izimbondela zokuqukethwe ukuze ubonise izinhlu zezixhumanisi nokunye okwengeziwe nge-plugin eyehlayo ye-Bootstrap.

Uhlolojikelele

Okwehliswayo kuyaguquleka, imbondela yomongo yokubonisa izinhlu zezixhumanisi nokuningi. Enziwe asebenzisane ne-plugin ye-JavaScript eyehlayo ye-Bootstrap efakiwe. Aguqulwa ngokuchofoza, hhayi ngokuhambisa phezulu; lesi yisinqumo somklamo wamabomu .

Okwehliswayo kwakhelwe kulabhulali yezinkampani zangaphandle, i- Popper.js , ehlinzeka ngokuma okuguquguqukayo nokutholwa kwembobo yokubuka. Qiniseka ukuthi ufaka i- popper.min.js ngaphambi kwe-JavaScript ye-Bootstrap noma sebenzisa bootstrap.bundle.min.js/ bootstrap.bundle.jsequkethe i-Popper.js. I-Popper.js ayisetshenziselwa ukubeka okwehlayo kuma-navbar nakuba ukuma okuguquguqukayo kungadingeki.

Uma wakha i-JavaScript yethu ngomthombo, idingautil.js .

Ukufinyeleleka

Izinga le- WAI ARIA role="menu" lichaza iwijethi yangempela , kodwa lokhu kuqondiswe kumamenyu afana nohlelo lokusebenza aqalisa izenzo noma imisebenzi. Amamenyu e -ARIA angaqukatha kuphela izinto zemenyu, izinto zemenyu yebhokisi lokuhlola, izinto zemenyu yezinkinobho zomsakazo, amaqembu ezinkinobho zomsakazo, namamenyu amancane.

Okwehliswayo kwe-Bootstrap, ngakolunye uhlangothi, kuklanyelwe ukuthi kube yijenerikhi futhi kusebenze ezimeni ezahlukahlukene kanye nezakhiwo zokumaka. Isibonelo, kungenzeka ukudala okwehliswayo okuqukethe okokufaka okwengeziwe nezilawuli zefomu, njengezinkambu zokusesha noma amafomu okungena ngemvume. Ngalesi sizathu, i-Bootstrap ayilindele (noma yengeze ngokuzenzakalelayo) noma yiziphi roleizibaluli aria-ezidingekayo kumamenyu e -ARIA eqiniso. Ababhali kuyodingeka bafake lezi zibaluli eziqondile ngokwabo.

Kodwa-ke, i-Bootstrap iyengeza usekelo olwakhelwe ngaphakathi lokusebenzisana kwemenyu yekhibhodi ejwayelekile, njengokukwazi ukuhamba phakathi .dropdown-itemkwezakhi ngazinye usebenzisa okhiye bekhesa nokuvala imenyu ESCngokhiye.

Izibonelo

Goqa inguquko yokudonsela phansi (inkinobho noma isixhumanisi sakho) kanye nemenyu yokudonsela phansi ngaphakathi .dropdown, noma enye into ememezela position: relative;. Okwehliswayo kungase kuqaliswe kusuka <a>noma ama <button>-elementi ukuze kulingane kangcono nezidingo zakho ezingaba khona.

Inkinobho eyodwa

Noma iyiphi ingoma eyodwa .btningashintshwa ibe okokudonsela phansi ngezinye izinguquko zemakhaphu. Nansi indlela ongazisebenzisa ngayo noma yiziphi <button>izici:

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Dropdown button
  </button>
  <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <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>

Futhi ngama- <a>elementi:

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

  <div class="dropdown-menu" aria-labelledby="dropdownMenuLink">
    <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>

Ingxenye engcono kakhulu ukuthi ungakwenza lokhu nganoma yikuphi okuhlukile kwenkinobho, futhi:

<!-- Example single danger button -->
<div class="btn-group">
  <button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" 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>

Inkinobho yokuhlukanisa

Ngokufanayo, dala okwehliswayo kwenkinobho yokuhlukanisa okunophawu olufanayo nolwehlayo lwenkinobho eyodwa, kodwa ngokungezwa kwesikhala .dropdown-toggle-splitesifanele endaweni yokunakekela okwehlayo.

Sisebenzisa lesi sigaba esengeziwe ukuze sinciphise okuvundlile paddingnhlangothi zombili ze-caret ngo-25% futhi sisuse margin-leftlokho okwengezwe ekwehliseni phansi kwezinkinobho ezivamile. Lezo zinguquko ezengeziwe zigcina i-caret igxile enkinobheni yokuhlukanisa futhi inikeza indawo yokushaya enosayizi ofanele eduze kwenkinobho eyinhloko.

<!-- 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-haspopup="true" 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>

Ukulinganisa

Okwehliswayo kwezinkinobho kusebenza ngezinkinobho zabo bonke osayizi, okuhlanganisa nezinkinobho ezizenzakalelayo nezihlukanisayo ezidonsela phansi.

    <span class="sr-only">Toggle Dropdown</span>
  </button>
  <div class="dropdown-menu">
    <!-- Dropdown menu links -->
  </div>
</div>

I-Droright

Qalisa amamenyu okwehlayo kwesokudla sezakhi ngokwengeza .droprightkusici esingumzali.

<!-- Default dropright button -->
<div class="btn-group dropright">
  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

      <!-- Dropdown menu links -->
    </div>
  </div>
  <button type="button" class="btn btn-secondary">
    Split dropleft
  </button>
</div>

Ngokomlando okuqukethwe kwemenyu eyehlayo bekufanele kube izixhumanisi, kodwa akusenjalo nge-v4. Manje ungakhetha ukusebenzisa <button>izici kokwehliswayo kwakho esikhundleni sika- <a>s nje.

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenu2" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Dropdown
  </button>
  <div class="dropdown-menu" aria-labelledby="dropdownMenu2">
    <button class="dropdown-item" type="button">Action</button>
    <button class="dropdown-item" type="button">Another action</button>
    <button class="dropdown-item" type="button">Something else here</button>
  </div>
</div>

Ungakwazi futhi ukudala izinto ezidonsela phansi ezingasebenzisani nge- .dropdown-item-text. Zizwe ukhululekile ukwenza isitayela ngokuqhubekayo nge-CSS yangokwezifiso noma izinsiza zombhalo.

<div class="dropdown-menu">
  <span class="dropdown-item-text">Dropdown item text</span>
  <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>

Iyasebenza

Engeza .activeezintweni kokwehliswayo ukuze wenze isitayela njengezisebenzayo .

<div class="dropdown-menu">
  <a class="dropdown-item" href="#">Regular link</a>
  <a class="dropdown-item active" href="#">Active link</a>
  <a class="dropdown-item" href="#">Another link</a>
</div>

Ikhutshaziwe

Engeza .disabledezintweni kokwehliswayo ukuze wenze isitayela njengezikhutshaziwe .

<div class="dropdown-menu">
  <a class="dropdown-item" href="#">Regular link</a>
  <a class="dropdown-item disabled" href="#" tabindex="-1" aria-disabled="true">Disabled link</a>
  <a class="dropdown-item" href="#">Another link</a>
</div>

Ngokuzenzakalela, imenyu yokudonsela phansi imiswa ngokuzenzakalelayo ngo-100% ukusuka phezulu nangakwesokunxele somzali wayo. Engeza .dropdown-menu-rightkokuthi a .dropdown-menuukuze uqondanise kwesokudla imenyu eyehlayo.

Amakhanda phezulu! Okwehliswayo kubekwe ngenxa ye-Popper.js (ngaphandle uma kuqukethwe ku-navbar).

<div class="btn-group">
  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Right-aligned menu
  </button>
  <div class="dropdown-menu dropdown-menu-right">
    <button class="dropdown-item" type="button">Action</button>
    <button class="dropdown-item" type="button">Another action</button>
    <button class="dropdown-item" type="button">Something else here</button>
  </div>
</div>

Ukuqondanisa okusabelayo

Uma ufuna ukusebenzisa ukuqondanisa okusabelayo, khubaza ukuma okuguquguqukayo ngokungeza data-display="static"isibaluli futhi usebenzise izigaba ezisabelayo zokuhlukahluka.

Ukuze uqondanise kwesokudla imenyu eyehlayo nendawo ehlukanisiwe enikeziwe noma enkulu, engeza .dropdown-menu{-sm|-md|-lg|-xl}-right.

<div class="btn-group">
  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" data-display="static" aria-haspopup="true" aria-expanded="false">
    Left-aligned but right aligned when large screen
  </button>
  <div class="dropdown-menu dropdown-menu-lg-right">
    <button class="dropdown-item" type="button">Action</button>
    <button class="dropdown-item" type="button">Another action</button>
    <button class="dropdown-item" type="button">Something else here</button>
  </div>
</div>

Ukuze uqondanise kwesokunxele imenyu eyehlayo nendawo ehlukanisiwe enikeziwe noma enkulu, engeza .dropdown-menu-rightfuthi .dropdown-menu{-sm|-md|-lg|-xl}-left.

<div class="btn-group">
  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" data-display="static" aria-haspopup="true" aria-expanded="false">
    Right-aligned but left aligned when large screen
  </button>
  <div class="dropdown-menu dropdown-menu-right dropdown-menu-lg-left">
    <button class="dropdown-item" type="button">Action</button>
    <button class="dropdown-item" type="button">Another action</button>
    <button class="dropdown-item" type="button">Something else here</button>
  </div>
</div>

Qaphela ukuthi awudingi ukwengeza data-display="static"isibaluli kuzinkinobho ezidonsela phansi kuma-navbar, njengoba i-Popper.js ingasetshenziswa kuma-navbar.

Izihloko

Engeza unhlokweni kulebula izigaba zezenzo kunoma iyiphi imenyu eyehlayo.

<div class="dropdown-menu">
  <h6 class="dropdown-header">Dropdown header</h6>
  <a class="dropdown-item" href="#">Action</a>
  <a class="dropdown-item" href="#">Another action</a>
</div>

Abahlukanisi

Hlukanisa amaqembu ezinto zemenyu ezihlobene ngesihlukanisi.

<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>

Umbhalo

Beka noma imuphi umbhalo we-freeform ngaphakathi kwemenyu eyehlayo onombhalo futhi usebenzise izinsiza zokuhlukanisa isikhala . Qaphela ukuthi cishe uzodinga izitayela zokulinganisa ezengeziwe ukuze ucindezele ububanzi bemenyu.

<div class="dropdown-menu p-4 text-muted" style="max-width: 200px;">
  <p>
    Some example text that's free-flowing within the dropdown menu.
  </p>
  <p class="mb-0">
    And this is more example text.
  </p>
</div>

Amafomu

Faka ifomu kumenyu eyehlayo, noma ulenze libe yimenyu eyehlayo, futhi usebenzise imajini noma izinto zokunamathisela ukuze ulinikeze isikhala esingesihle osidingayo.

<div class="dropdown-menu">
  <form class="px-4 py-3">
    <div class="form-group">
      <label for="exampleDropdownFormEmail1">Email address</label>
      <input type="email" class="form-control" id="exampleDropdownFormEmail1" placeholder="[email protected]">

Ukusetshenziswa

Ngezibaluli zedatha noma i-JavaScript, i-plugin eyehlayo iguqula okuqukethwe okufihliwe (amamenyu okwehliswayo) ngokuguqula .showikilasi entweni yohlu lwabazali. Isibaluli data-toggle="dropdown"kuthenjelwe kuso ekuvaleni amamenyu okwehlayo ezingeni lesicelo, ngakho-ke kuwumqondo omuhle ukusisebenzisa njalo.

Kumadivayisi anikwe amandla ukuthinta, ukuvula okwehliswayo kwengeza izibambi ezingenalutho ( $.noop) mouseoverezinganeni eziseduze ze- <body>elementi. Lokhu kugebenga okuvunyiwe ukuthi kubi kuyadingeka ukuze kulungiswe okuthile ekuthunyelweni komcimbi we-iOS , okungavimbela ukuthepha noma yikuphi ngaphandle kokwehliswayo ukuthi kungacuphi ikhodi evala okwehliswayo. Uma okwehliswayo sekuvaliwe, lezi mouseoverzibambi ezengeziwe ezingenalutho ziyasuswa.

Ngezibaluli zedatha

Engeza data-toggle="dropdown"kusixhumanisi noma inkinobho ukuze uguqule okwehliswayo.

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

Nge-JavaScript

Shayela okwehliswayo nge-JavaScript:

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

`data-toggle="dropdown"`kusadingeka

Kungakhathaliseki ukuthi ushayela okwehliswayo ucingo nge-JavaScript noma esikhundleni salokho sebenzisa i-data-api, data-toggle="dropdown"kuyadingeka njalo ukuthi ube khona kusici sokuqala sokwehliswayo.

Izinketho

Izinketho zingadluliswa ngezibaluli zedatha noma i-JavaScript. Ukuze uthole izibaluli zedatha, faka igama lenketho kokuthi data-, njengaku data-offset="".

Igama	Uhlobo	Okuzenzakalelayo	Incazelo
offset	inombolo \| umucu \| umsebenzi	0	I-offset yokwehliswayo ihlobene nethagethi yakhona. Uma umsebenzi usetshenziselwa ukunquma i-offset, ubizwa ngento equkethe idatha ye-offset njenge-agumenti yayo yokuqala. Umsebenzi kufanele ubuyisele into enesakhiwo esifanayo. Into eqalisayo inodi ye-DOM idluliswa njengempikiswano yesibili. Ukuze uthole ulwazi olwengeziwe bheka ku-Popper.js's offset docs .
flip	boolean	iqiniso	Vumela Okwehlayo ukuthi kuphendulwe uma kwenzeka kugqagqana kusici sesithenjwa. Ukuze uthole ulwazi olwengeziwe bheka ku-Popper.js's flip docs .
umngcele	umucu \| isici	'scrollParent'	Umkhawulo womkhawulo wokuchichima wemenyu eyehlayo. Yamukela amanani we- `'viewport'`, `'window'`, `'scrollParent'`, noma ireferensi ye-HTMLElement (JavaScript kuphela). Ukuze uthole ulwazi olwengeziwe bheka ku-Popper.js's preventOverflow amadokhumenti .
ireferensi	umucu \| isici	'guqula'	Isici esiyisethenjwa semenyu eyehlayo. Yamukela amanani okuthi `'toggle'`, `'parent'`, noma ireferensi Yesici se-HTML. Ukuze uthole ulwazi olwengeziwe bheka ku-Popper.js's referenceObject docs .
isibonisi	umucu	'dynamic'	Ngokuzenzakalelayo, sisebenzisa i-Popper.js ukuze simise okuguquguqukayo. Khubaza lokhu nge- `static`.
popperConfig	null \| into	null	Ukuze uguqule ukucushwa kwe-Bootstrap okuzenzakalelayo kwe-Popper.js, bona ukucushwa kwe-Popper.js

Qaphela boundaryukuthi isethwe nini kunoma yiliphi inani ngaphandle kokuthi 'scrollParent', isitayela position: staticsisetshenziswa .dropdownesitsheni.
