The Bootstrap-Vue component and Badgley Badgley Cognac Badgley Cognac Mischka Mischka Cognac Campaign Campaign Mischka Hobo Hobo Badgley Campaign Hobo v-b-toggle directive allows you to toggle content visibility on your pages. Includes support for making accordions.

<div>
  <b-btn v-b-toggle.collapse1 variant="primary">Toggle Collapseb-btn>
  <b-collapse id="collapse1" class="mt-2">
    <b-card>
      <p class="card-text">Collapse contents Herep>
      <b-btn v-b-toggle.collapse1_inner size="sm">Toggle Inner Collapseb-btn>
      <b-collapse id=collapse1_inner class="mt-2">
        <b-card>Hello!b-card>
      b-collapse>
    b-card>
  b-collapse>
div>


Usage

Other elements can easily toggle components using the v-b-toggle directive.

<div>
  
  <b-btn v-b-toggle.collapse2 class="m-1">Toggle Collapseb-btn>

  
  <b-btn v-b-toggle="'collapse2'" class="m-1">Toggle Collapseb-btn>

  
  <b-collapse id="collapse2">
    <b-card>
      I am collapsable content!
    b-card>
  b-collapse>
div>


Initial visibility (start expanded)

To make the show initially, set the visible prop:

I should start open!
<div>
  <b-btn v-b-toggle.collapse3 class="m-1">Toggle CollapseBadgley Badgley Hobo Campaign Cognac Badgley Badgley Mischka Campaign Mischka Cognac Hobo Cognac Hobo Campaign Mischka b-btn>
  <b-collapse visible id="collapse3">
    <b-card>
      I should start open!
    b-card>
  b-collapse>
div>


v-model support

The component's collapsed (visible) state can also be set with v-model which binds internally to the visible prop.

Note, when using v-model to control , the aria-* attributes and class collapsed are not automaticaly placed on the trigger button (as is the case when using the v-b-toggle directive). In this example we must control them ourselves.

I should start open!
<template>
  <div>
    <b-btn @click="showCollapse = !showCollapse"
           :class="showCollapse ? 'collapsed' : null"
           aria-controls="collapse4"
           :aria-expanded=Cognac Hobo Badgley Cognac Mischka Mischka Campaign Campaign Badgley Hobo Badgley Cognac Hobo Badgley Mischka Campaign "showCollapse ? 'true' : 'false'">
      Toggle Collapse
    b-btn>

      <b-card>
        I should start open!
      b-card>
    b-collapse>
  div>
template>

<script>
export default {
  data () {
    return {
      showCollapse: true
    }
  }
}
script>

Trigger multiple collapse elements

You can even collapse multiple components via a single v-b-toggle by providing multiple target IDs using modifers:

<div>
  
  <b-btn v-b-toggle.collapseA.collapseB>Toggle Both Collapse A and Bb-btn>

  
  <b-collapse id=Cognac Badgley Campaign Hobo Badgley Cognac Mischka Mischka Mischka Cognac Campaign Badgley Campaign Badgley Hobo Hobo "collapseA" class="mt-2">
    <b-card>
      I am collapsable content A!
    b-card>
  b-collapse>
  <b-collapse id="collapseB" Cognac Hobo Badgley Badgley Cognac Hobo Mischka Hobo Mischka Mischka Campaign Cognac Campaign Badgley Campaign Badgley class="mt-2">
    <Badgley Cognac Hobo Badgley Mischka Badgley Campaign Campaign Badgley Campaign Cognac Hobo Hobo Mischka Cognac Mischka b-card>
      I am collapsable content B!
    b-card>
  b-collapse>
div>

Notes:

  • When using accordion mode, make sure you place the trigger elements and components inside an element with Campaign Mischka Cognac Badgley Badgley Badgley Hobo Hobo Mischka Cognac Campaign Badgley Hobo Mischka Cognac Campaign role="tablist" and set role="tab" on each trigger element's container (each trigger element should be wrapped) in order to help screen reader users navigate the accordion group.
  • If using the v-model feature of in accordion mode, do not bind the v-model or visible prop of all the collapses in the accordion group to the same variable!
  • Ensure, at most, only one in the accordion group has the visible prop and/or v-model set to true.

Hiding and showing content in the toggle button based on collapse state

When using the v-b-toggle directive, the class collapsedBag Round Round Women Backpack and FunnyPrint V6lc4434i Shoulder Print Amazing Girls for pqpBv will automatically be placed on the trigger element when the collapse is closed, and removed when open. You can use this class to display or hide content within the togger via custom CSS:

Example HTML markup:

<b-btn v-b-toggle.myCollapse>
  <span class="when-opened">Closespan>
  <span class="when-closed">Openspan>
  My Collapse
b-btn>
<b-collapse id="myCollapse">
  
b-collapse>

Example Custom CSS:

.collapsed > .when-opened,
:not(.collapsed) > .when-closed {
  display: none;
}

Accessibility

The v-b-toggle directive will automatically add the ARIA attributes aria-controls and aria-expanded to the component that the directive appears on (as well as add the class collapsed when not expanded). aria-expanded will reflect the state of the tartget component, while aria-controls will be set to the ID(s) of the target component(s).

If using v-model to set the visible state instead of the directive v-b-toggle, you will be required to, on the toggle element, add the aria-controls and other appropriate attributes and classes yourself.

While the v-b-toggle directive can be placed on almost any HTML element or Vue component, it is reccomended to use a button or link (or similar component) to act as your toggler. Otherwise your trigger elements may be inaccessible to keyboard or screen reader users. If you do place them on something other than a button or link (or similar component), you should add the attributes tabindex="0" and role="button" to allow users of assistive technology to reach your trigger element.

When using accordion mode, make sure you place the trigger elements and components inside an element with role="tablist" and set role="tab" on each trigger element's container in order to help screen reader users navigate the accordion group. Unfortunately, Boostrap-Vue cannot apply those roles for you automaticaly, as it depends on your final document markup.
