Botali ya mozindo

Ba dropdowns ezali toggleable, ba overlays contextuels mpo na kolakisa ba liste ya ba liens mpe mingi mosusu. Bazali kosala interactif na plugin ya JavaScript oyo ezali kokita ya Bootstrap oyo ezali na kati. Bazali ko toggled na ko cliquer, na ko hover te; oyo ezali ekateli ya kosala na mokano .

Ba dropdowns etongami na bibliothèque ya troisième partie, Popper , oyo epesaka positionnement dynamique mpe détection ya port de vue. Sala makasi otia popper.min.js liboso ya JavaScript ya Bootstrap to salela bootstrap.bundle.min.js/ bootstrap.bundle.jsoyo ezali na Popper. Popper esalelamaka te mpo na ko positionner ba dropdowns na ba navbars atako lokola positionnement dynamique esengeli te.

Soki ozali kotonga JavaScript na biso uta na source, esengiutil.js .

Kozala na makoki ya kozwa yango

Norme WAI ARIA elimboli role="menu"widget ya solo , kasi oyo ezali ya sikisiki na ba menu lokola ya bosaleli oyo ebandisaka misala to misala. Ba menu ya ARIA ekoki kozala kaka na biloko ya menu, biloko ya menu ya case ya kotiya elembo, biloko ya menu ya bouton ya radio, bituluku ya bouton ya radio, mpe ba sous-menu.

Ba dropdowns ya Bootstrap, na ngambo mosusu, esalemi mpo na kozala générique mpe ekoki kosalelama na ba situations ndenge na ndenge mpe na ba structures ya marquage. Na ndakisa, ezali na nzela ya kosala ba dropdowns oyo ezali na ba entrées ya kobakisa mpe ba contrôles ya formulaire, lokola ba champs ya recherche to ba formulaires ya login. Mpo na ntina oyo, Bootstrap ezali kozela te (to kobakisa na ndenge ya automatique) moko ya rolempe aria-bizaleli oyo esengeli mpo na ba menu ya solosolo ya ARIA . Bakomi bakosengela kokɔtisa bango moko bizaleli wana ya sikisiki mingi.

Kasi, Bootstrap ebakisi lisungi oyo etongami na kati mpo na mingi ya boyokani ya menu ya klaviatware ya momesano, lokola makoki ya kotambola na kati ya .dropdown-itembiloko mokomoko na kosaleláká bafungola ya kursɛrɛ mpe kokanga menu na ESCfungola.

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-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 handlers ya pamba ( $.noop) na bana ya mbala moko ya 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.
