Witondere kongera aria-expandedkubintu bigenzura. Iyi miterere yerekana neza uko ibintu bimeze ubu ibintu byangirika bifitanye isano no kugenzura abasomyi hamwe na tekinoroji ifasha. Niba ikintu gishobora gusenyuka gifunzwe byanze bikunze, ikiranga kugenzura ikintu kigomba kugira agaciro ka aria-expanded="false". Niba washyizeho ikintu gishobora kugwa kugirango ufungure byanze bikunze ukoresheje urwego show, shyira aria-expanded="true"kugenzura aho. Gucomeka izahita ihindura iyi miterere kubigenzuzi ukurikije niba ikintu gishobora kugwa cyarafunguwe cyangwa kidafunzwe (binyuze kuri JavaScript, cyangwa kubera ko umukoresha yatangije ikindi kintu cyo kugenzura nacyo kijyanye nibintu bimwe bishobora kugwa).

Ikoreshwa

Gusenyuka plugin ikoresha ibyiciro bike kugirango ikemure ibintu biremereye:

  • .collapseahisha ibirimo
  • .collapse.showyerekana ibirimo
  • .collapsing is added when the transition starts, and removed when it finishes

These classes can be found in _transitions.scss.

Via data attributes

Just add data-toggle="collapse" and a data-target to the element to automatically assign control of one or more collapsible elements. The data-target attribute accepts a CSS selector to apply the collapse to. Be sure to add the class collapse to the collapsible element. If you’d like it to default open, add the additional class show.

To add accordion-like group management to a collapsible area, add the data attribute data-parent="#selector". Refer to the demo to see this in action.

Via JavaScript

Enable manually with:

$('.collapse').collapse()

Options

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

Name Type Default Description
parent selector | jQuery object | DOM element false If parent is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent on the card class). The attribute has to be set on the target collapsible area.
toggle boolean true Toggles the collapsible element on invocation

Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our JavaScript documentation for more information.

.collapse(options)

Activates your content as a collapsible element. Accepts an optional options object.

$('#myCollapsible').collapse({
  toggle: false
})

.collapse('toggle')

Toggles a collapsible element to shown or hidden. Returns to the caller before the collapsible element has actually been shown or hidden (i.e. before the shown.bs.collapse or hidden.bs.collapse event occurs).

.collapse('show')

Shows a collapsible element. Returns to the caller before the collapsible element has actually been shown (i.e. before the shown.bs.collapse event occurs).

.collapse('hide')

Hides a collapsible element. Returns to the caller before the collapsible element has actually been hidden (i.e. before the hidden.bs.collapse event occurs).

.collapse('dispose')

Destroys an element’s collapse.

Events

Bootstrap’s collapse class exposes a few events for hooking into collapse functionality.

Event Type Description
show.bs.collapse Ibirori birasa ako kanya mugihe showurugero rwitwa.
yerekanwe.bs.isenyuka Ibi birori birukanwa mugihe ikintu cyo gusenyuka cyakozwe kigaragara kubakoresha (bizategereza ko inzibacyuho ya CSS irangira).
guhisha.bs. gusenyuka Iki gikorwa kirahita gihita iyo hideuburyo bwahamagawe.
guhisha.bs.isenyuka Ibirori birukanwa mugihe ikintu cyo gusenyuka cyihishe kumukoresha (uzategereza ko inzibacyuho ya CSS irangira). 
$('#myCollapsible').on('hidden.bs.collapse', function () {
  // do something...
})
