Lokola eteni ya approche ya ba variables CSS oyo ezali ko évoluer ya Bootstrap, ba dropdowns esalela sikoyo ba variables CSS locales na .dropdown-menupona personnalisation ya temps réel oyo ematisami. Ba valeurs pona ba variables ya CSS etiamaki na nzela ya Sass, yango wana personnalisation ya Sass ezali kaka kosungama, pe.

Kosalela yango

Na nzela ya ba attributs ya ba données to JavaScript, plugin oyo ezali kokita ebalusaka makambo oyo ebombami (ba menu oyo ezali kokita) na kobongola .showkelasi na moboti .dropdown-menu. Attribut data-bs-toggle="dropdown"etie motema mpo na kokanga ba menu ya kokita na niveau ya application, yango wana ezali likanisi malamu kosalela yango ntango nyonso.

Na ba appareils oyo ekoki ko toucher, kofungola dropdown ebakisi ba mouseoverhandlers ya pamba na bana ya mbala moko ya <body>élément. This admittedly ugly hack is necessary to work around a quirk in iOS’ event delegation , oyo soki te elingaki kopekisa robinet esika nyonso libanda ya dropdown e déclencher code oyo ekanga dropdown. Soki kaka dropdown ekangami, ba mouseoverhandlers oyo ya pamba ya kobakisa elongolamaka.

Na nzela ya ba attributs ya ba données

Bakisa data-bs-toggle="dropdown"na lien to na bouton mpo na kobongola esika oyo ezali kokita.

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

Na nzela ya JavaScript

Benga ba dropdowns na nzela ya JavaScript:

const dropdownElementList = document.querySelectorAll('.dropdown-toggle')
const dropdownList = [...dropdownElementList].map(dropdownToggleEl => new bootstrap.Dropdown(dropdownToggleEl))

`data-bs-toggle="dropdown"`esɛngami naino

Indépendamment soki obengi dropdown na yo na nzela ya JavaScript to na esika na yango kosalela data-api, data-bs-toggle="dropdown"esengeli ntango nyonso kozala présent na élément déclencheur ya dropdown.

Makambo oyo okoki kopona

Lokola ba options ekoki koleka na nzela ya ba attributs ya ba données to JavaScript, okoki kobakisa kombo ya option na data-bs-, lokola na data-bs-animation="{value}". Sala makasi o changer type ya cas ya kombo ya option depuis “ camelCase ” na “ kebab-case ” tango ozali koleka ba options via ba attributs ya ba données. Na ndakisa, salelá data-bs-custom-class="beautifier"na esika ya data-bs-customClass="beautifier".

Kobanda na Bootstrap 5.2.0, ba composants nionso esungaka attribut ya ba données réservées expérimentalesdata-bs-config oyo ekoki ko louer configuration ya composant simple lokola chaîne JSON. Tango élément moko ezali data-bs-config='{"delay":0, "title":123}'na na ba data-bs-title="456"attributs, valeur ya suka titleekozala 456mpe ba attributs ya ba données separates eko overrider ba valeurs oyo epesami na data-bs-config. En plus, ba attributs ya ba données oyo ezali ezali capable ya ko louer ba valeurs JSON lokola data-bs-delay='{"show":0,"hide":150}'.

Nkombo	Lolenge	Mbeba	Ndimbola
`autoClose`	boolean, molongo	`true`	Configurer comportement ya auto close ya dropdown: `true`- esika ya kokita ekokangama na kofina libanda to na kati ya menu ya kokita. `false`- déroulant ekokangama na kofina bouton toggle mpe kobenga manuellement `hide`to `toggle`méthode. (Lisusu ekokangama te na kofina `esc`touche) `'inside'`- esika ya kokita ekokangama (kaka) na kofina na kati ya menu ya kokita. `'outside'`- esika ya kokita ekokangama (kaka) na kofina libanda ya menu ya kokita. Liyebisi: dropdown ekoki ntango nyonso kokangama na `ESC`fungola.
`boundary`	molongo, eloko	`'clippingParents'`	Frontière ya contrainte ya débordement ya menu ya kokita (etali kaka modificateur ya preventOverflow ya Popper). Na ndenge ya libela ezali `clippingParents`mpe ekoki kondima référence ya HTMLElement (na nzela ya JavaScript kaka). Mpo na koyeba makambo mingi tala Docs ya detectOverflow ya Popper .
`display`	shene	`'dynamic'`	Par défaut, tosalelaka Popper pona positionnement dynamique. Désactiver oyo na `static`.
`offset`	array, molongo, mosala	`[0, 2]`	Offset ya dropdown par rapport na cible na yango. Okoki koleka molongo na ba attributs ya ba données na ba valeurs oyo ekabwani na virgule lokola: `data-bs-offset="10,20"`. Tango fonction esalelami pona koyeba offset, ebengamaka na objet oyo ezali na placement ya popper, référence, na ba rects ya popper lokola argument na yango ya liboso. Node DOM ya élément déclencheur eleki lokola argument ya mibale. Fonction esengeli kozongisa array oyo ezali na ba nombres mibale: skidding , distance . Mpo na koyeba makambo mingi tala Docs ya offset ya Popper .
`popperConfig`	null, eloko, mosala	`null`	Mpo na kobongola configuration ya Popper ya liboso ya Bootstrap, tala configuration ya Popper . Tango fonction moko esalelami pona kosala configuration ya Popper, ebengami na objet oyo ezali na configuration ya Popper par défaut ya Bootstrap. Esalisaka yo osalela mpe osangisa oyo ya liboso na configuration na yo moko. Fonction esengeli kozongisa objet ya configuration pona Popper.
`reference`	molongo, eloko, eloko	`'toggle'`	Elemento ya référence ya menu oyo ezali kokita. Endimi motuya ya `'toggle'`, `'parent'`, référence HTMLElement to eloko oyo epesaka `getBoundingClientRect`. Mpo na koyeba makambo mingi tala ba docs ya constructeur ya Popper mpe ba docs ya élément virtuel .

Kosalela fonction na`popperConfig`

const dropdown = new bootstrap.Dropdown(element, {
  popperConfig(defaultBsPopperConfig) {
    // const newPopperConfig = {...}
    // use defaultBsPopperConfig if needed...
    // return newPopperConfig
  }
})

Ba méthodes ya kosala

Metode	Ndimbola
`dispose`	Ebebisaka dropdown ya élément moko. (Elongolaka ba données oyo ebombami na élément DOM)
`getInstance`	Méthode statique oyo e permettre yo ozua instance déroulante associée na élément DOM, okoki kosalela yango boye: `bootstrap.Dropdown.getInstance(element)`.
`getOrCreateInstance`	Méthode statique oyo ezongisaka instance ya kokita oyo ezo sangana na élément DOM to ezo sala ya sika au cas où ezalaki initialisé te. Okoki kosalela yango boye: `bootstrap.Dropdown.getOrCreateInstance(element)`.
`hide`	Ebombaka menu oyo ezali kokita ya navbar to navigation oyo ezali na onglet oyo epesami.
`show`	Ezali kolakisa menu oyo ezali kokita ya navbar to navigation oyo ezali na onglet oyo epesami.
`toggle`	Ezali kobongola menu oyo ezali kokita ya navbar to navigation oyo ezali na onglet oyo epesami.
`update`	Ezali kosala mikolo oyo position ya dropdown ya élément moko.

Makambo oyo esalemaki

Ba événements nionso ya dropdown ezo betama na élément toggling et puis ezo bubbler likolo. Donc okoki pe kobakisa ba auditeurs ya événement na .dropdown-menuélément parent ya '. hide.bs.dropdownmpe hidden.bs.dropdownmakambo ezali na clickEventpropriété (kaka tango lolenge ya Evenement ya ebandeli ezali click) oyo ezali na Objet ya Evenement mpo na événement ya cliquage.

Lolenge ya likambo	Ndimbola
`hide.bs.dropdown`	Epelisaka mbala moko tango `hide`méthode ya instance ebengami.
`hidden.bs.dropdown`	Ebetami tango dropdown esili kobombama na mosaleli mpe ba transitions ya CSS esili.
`show.bs.dropdown`	Ezo benga mbala moko tango `show`méthode ya instance ebengami.
`shown.bs.dropdown`	Elongolami tango dropdown esalemi komonana na mosaleli mpe ba transitions ya CSS esili.

const myDropdown = document.getElementById('myDropdown')
myDropdown.addEventListener('show.bs.dropdown', event => {
