Vue Collapse Component

Vue collapse component toggles the visibility of content across your project with a few classes and some scripts. Useful for a large amount of content.

How it works #

The collapse component is used to show and hide content. Buttons or anchors are used as triggers that are mapped to specific elements you toggle. Collapsing an element will animate the height from its current value to 0. Given how CSS handles animations, you cannot use padding on a .collapse element. Instead, use the class as an independent wrapping element.

Example #

You can use a link or a button component.

Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.

<template>
  <CButton color="primary" href="#" @click="visible = !visible">Link</CButton>
  <CButton color="primary" @click="visible = !visible">Button</CButton>
  <CCollapse :visible="visible">
    <CCard class="mt-3">
      <CCardBody>
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson
        ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt
        sapiente ea proident.
      </CCardBody>
    </CCard>
  </CCollapse>
</template>
<script>
  export default {
    data() {
      return { 
        visible: false,
      }
    }
  }
</script> 

Horizontal #

The collapse plugin also supports horizontal collapsing. Add the horizontal property to transition the width instead of height and set a width on the immediate child element.

This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered.

<template>
  <CButton class="mb-3" color="primary" aria-expanded={visible} aria-controls="collapseWidthExample" @click="visibleHorizontal = !visibleHorizontal">Button</CButton>
  <div style="min-height: 120px">
    <CCollapse horizontal :visible="visibleHorizontal">
      <CCard style="width: 300px">
        <CCardBody>
          This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered.
        </CCardBody>
      </CCard>
    </CCollapse>
  </div>
</template>
<script>
  export default {
    data() {
      return { 
        visibleHorizontal: false,
      }
    }
  }
</script>

Multiple targets #

A <CButton> can show and hide multiple elements.
