Collapsible

A collapsible element to toggle visibility of its content.

Usage

Use a Button or any other component in the default slot of the Collapsible.

Then, use the #content slot to add the content displayed when the Collapsible is open.

<template>
  <UCollapsible class="flex flex-col gap-2 w-48">
    <UButton
      label="Open"
      color="neutral"
      variant="subtle"
      trailing-icon="i-lucide-chevron-down"
      block
    />

    <template #content>
      <Placeholder class="h-48" />
    </template>
  </UCollapsible>
</template>

Disabled

Use the disabled prop to disable the Collapsible.

disabled

<template>
  <UCollapsible class="flex flex-col gap-2 w-48" disabled>
    <UButton
      label="Open"
      color="neutral"
      variant="subtle"
      trailing-icon="i-lucide-chevron-down"
      block
    />

    <template #content>
      <Placeholder class="h-48" />
    </template>
  </UCollapsible>
</template>

Examples

Control open state

You can control the open state by using the default-open prop or the v-model:open directive.

<script setup lang="ts">
const open = ref(true)

defineShortcuts({
  o: () => open.value = !open.value
})
</script>

<template>
  <UCollapsible v-model:open="open" class="flex flex-col gap-2 w-48">
    <UButton
      label="Open"
      color="neutral"
      variant="subtle"
      trailing-icon="i-lucide-chevron-down"
      block
    />

    <template #content>
      <Placeholder class="h-48" />
    </template>
  </UCollapsible>
</template>

In this example, leveraging defineShortcuts, you can toggle the Collapsible by pressing O.

This allows you to move the trigger outside of the Collapsible or remove it entirely.

With rotating icon

Here is an example with a rotating icon in the Button that indicates the open state of the Collapsible.

<template>
  <UCollapsible class="flex flex-col gap-2 w-48">
    <UButton
      class="group"
      label="Open"
      color="neutral"
      variant="subtle"
      trailing-icon="i-lucide-chevron-down"
      :ui="{
        trailingIcon: 'group-data-[state=open]:rotate-180 transition-transform duration-200'
      }"
      block
    />

    <template #content>
      <Placeholder class="h-48" />
    </template>
  </UCollapsible>
</template>
