Tree

TreeGitHub
A tree view component to display and interact with hierarchical data structures.

Usage

Use the Tree component to display a hierarchical structure of items.

<script setup lang="ts">
const items = ref([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          {
            label: 'useAuth.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          },
          {
            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          {
            label: 'Card.vue',
            icon: 'i-vscode-icons-file-type-vue'
          },
          {
            label: 'Button.vue',
            icon: 'i-vscode-icons-file-type-vue'
          }
        ]
      }
    ]
  },
  {
    label: 'app.vue',
    icon: 'i-vscode-icons-file-type-vue'
  },
  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree :items="items" />
</template>

Items

Use the items prop as an array of objects with the following properties:

  • icon?: string
  • label?: string
  • trailingIcon?: string
  • defaultExpanded?: boolean
  • disabled?: boolean
  • slot?: string
  • children?: TreeItem[]
  • onToggle?(e: Event): void
  • onSelect?(e?: Event): void
  • class?: any
  • ui?: { item?: ClassNameValue, itemWithChildren?: ClassNameValue, link?: ClassNameValue, linkLeadingIcon?: ClassNameValue, linkLabel?: ClassNameValue, linkTrailing?: ClassNameValue, linkTrailingIcon?: ClassNameValue, listWithChildren?: ClassNameValue }
A unique identifier is required for each item. The component will use the label prop as identifier if no get-key is provided. Ideally you should provide a get-key function prop to return a unique identifier. Alternatively, you can use the labelKey prop to specify which property to use as the unique identifier.
<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          {
            label: 'useAuth.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          },
          {
            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          {
            label: 'Card.vue',
            icon: 'i-vscode-icons-file-type-vue'
          },
          {
            label: 'Button.vue',
            icon: 'i-vscode-icons-file-type-vue'
          }
        ]
      }
    ]
  },
  {
    label: 'app.vue',
    icon: 'i-vscode-icons-file-type-vue'
  },
  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree :items="items" />
</template>

Multiple

Use the multiple prop to allow multiple item selections.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          {
            label: 'useAuth.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          },
          {
            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          {
            label: 'Card.vue',
            icon: 'i-vscode-icons-file-type-vue'
          },
          {
            label: 'Button.vue',
            icon: 'i-vscode-icons-file-type-vue'
          }
        ]
      }
    ]
  },
  {
    label: 'app.vue',
    icon: 'i-vscode-icons-file-type-vue'
  },
  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree multiple :items="items" />
</template>

Nested Soon

Use the nested prop to control whether the Tree is rendered with nested structure or as a flat list. Defaults to true.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          {
            label: 'useAuth.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          },
          {
            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          {
            label: 'Card.vue',
            icon: 'i-vscode-icons-file-type-vue'
          },
          {
            label: 'Button.vue',
            icon: 'i-vscode-icons-file-type-vue'
          }
        ]
      }
    ]
  },
  {
    label: 'app.vue',
    icon: 'i-vscode-icons-file-type-vue'
  },
  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree :nested="false" :items="items" />
</template>
When nested is false, all items are rendered at the same level with indentation to indicate hierarchy. This is useful for virtualization or drag and drop functionality.

Color

Use the color prop to change the color of the Tree.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          {
            label: 'useAuth.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          },
          {
            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          {
            label: 'Card.vue',
            icon: 'i-vscode-icons-file-type-vue'
          },
          {
            label: 'Button.vue',
            icon: 'i-vscode-icons-file-type-vue'
          }
        ]
      }
    ]
  },
  {
    label: 'app.vue',
    icon: 'i-vscode-icons-file-type-vue'
  },
  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree color="neutral" :items="items" />
</template>

Size

Use the size prop to change the size of the Tree.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          {
            label: 'useAuth.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          },
          {
            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          {
            label: 'Card.vue',
            icon: 'i-vscode-icons-file-type-vue'
          },
          {
            label: 'Button.vue',
            icon: 'i-vscode-icons-file-type-vue'
          }
        ]
      }
    ]
  },
  {
    label: 'app.vue',
    icon: 'i-vscode-icons-file-type-vue'
  },
  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree size="xl" :items="items" />
</template>

Trailing Icon

Use the trailing-icon prop to customize the trailing Icon of a parent node. Defaults to i-lucide-chevron-down.

If an icon is specified for an item, it will always take precedence over these props.
<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        trailingIcon: 'i-lucide-chevron-down',
        children: [
          {
            label: 'useAuth.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          },
          {
            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },

            icon: 'i-vscode-icons-file-type-vue'
          },
          {
            label: 'Button.vue',
            icon: 'i-vscode-icons-file-type-vue'
          }
        ]
      }
    ]
  },
  {
    label: 'app.vue',
    icon: 'i-vscode-icons-file-type-vue'
  },
  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree trailing-icon="i-lucide-arrow-down" :items="items" />
</template>
You can customize this icon globally in your app.config.ts under ui.icons.chevronDown key.
You can customize this icon globally in your vite.config.ts under ui.icons.chevronDown key.

Expanded Icon

Use the expanded-icon and collapsed-icon props to customize the icons of a parent node when it is expanded or collapsed. Defaults to i-lucide-folder-open and i-lucide-folder respectively.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app/',
    defaultExpanded: true,
    children: [

  {
    label: 'nuxt.config.ts',
    icon: 'i-vscode-icons-file-type-nuxt'
  }
])
</script>

<template>
  <UTree expanded-icon="i-lucide-book-open" collapsed-icon="i-lucide-book" :items="items" />
</template>
You can customize these icons globally in your app.config.ts under ui.icons.folder and ui.icons.folderOpen keys.
You can customize these icons globally in your vite.config.ts under ui.icons.folder and ui.icons.folderOpen keys.

Disabled

Use the disabled prop to prevent any user interaction with the Tree.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = ref<TreeItem[]>([
  {
    label: 'app',
    icon: 'i-lucide-folder',

                icon: 'i-vscode-icons-file-type-vue'
              }
            ]
          }
        ]
      }
    ]
  },
  {

])
</script>

<template>
  <UTree disabled :items="items" />
</template>
You can also disable individual items using item.disabled.

Examples

Control selected item(s)

You can control the selected item(s) by using the default-value prop or the v-model directive.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items: TreeItem[] = [
  {
    label: 'app/',
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          { label: 'useAuth.ts', icon: 'i-vscode-icons-file-type-typescript' },
          { label: 'useUser.ts', icon: 'i-vscode-icons-file-type-typescript' }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          { label: 'Card.vue', icon: 'i-vscode-icons-file-type-vue' },
          { label: 'Button.vue', icon: 'i-vscode-icons-file-type-vue' }
        ]
      }
    ]
  },
  { label: 'app.vue', icon: 'i-vscode-icons-file-type-vue' },
  { label: 'nuxt.config.ts', icon: 'i-vscode-icons-file-type-nuxt' }
]

const value = ref()
</script>

<template>
  <UTree v-model="value" :items="items" />
</template>

If you want to prevent an item from being selected, you can use the item.onSelect() property:

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items: TreeItem[] = [
  {
    label: 'app/',
    defaultExpanded: true,
    onSelect: (e: Event) => {
      e.preventDefault()
    },
    children: [
      {
        label: 'composables/',
        children: [
          { label: 'useAuth.ts', icon: 'i-vscode-icons-file-type-typescript' },
          { label: 'useUser.ts', icon: 'i-vscode-icons-file-type-typescript' }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          { label: 'Card.vue', icon: 'i-vscode-icons-file-type-vue' },
          { label: 'Button.vue', icon: 'i-vscode-icons-file-type-vue' }
        ]
      }
    ]
  },
  { label: 'app.vue', icon: 'i-vscode-icons-file-type-vue' },
  { label: 'nuxt.config.ts', icon: 'i-vscode-icons-file-type-nuxt' }
]
</script>

<template>
  <UTree :items="items" />
</template>
This lets you expand or collapse a parent item without selecting it.

Control expanded items

You can control the expanded items by using the default-expanded prop or the v-model directive.

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = [
  {
    label: 'app/',
    id: 'app',
    children: [
      {

        id: 'app/composables',
        children: [
          { label: 'useAuth.ts', icon: 'i-vscode-icons-file-type-typescript' },
          { label: 'useUser.ts', icon: 'i-vscode-icons-file-type-typescript' }
        ]
      },
      {
        label: 'components/',
        id: 'app/components',
        children: [
          { label: 'Card.vue', icon: 'i-vscode-icons-file-type-vue' },
          { label: 'Button.vue', icon: 'i-vscode-icons-file-type-vue' }
        ]
      }
    ]
  },
  { label: 'app.vue', id: 'app.vue', icon: 'i-vscode-icons-file-type-vue' },
  { label: 'nuxt.config.ts', id: 'nuxt.config.ts', icon: 'i-vscode-icons-file-type-nuxt' }
] satisfies TreeItem[]

const expanded = ref(['app', 'app/composables'])
</script>

<template>
  <UTree v-model:expanded="expanded" :items="items" :get-key="i => i.id" />
</template>

If you want to prevent an item from being expanded, you can use the item.onToggle() property:

<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items: TreeItem[] = [
  {
    label: 'app/',
    defaultExpanded: true,
    onToggle: (e: Event) => {
      e.preventDefault()

        label: 'composables/',
        children: [

          { label: 'useUser.ts', icon: 'i-vscode-icons-file-type-typescript' }
        ]
      },
      {

        defaultExpanded: true,
        children: [

  { label: 'nuxt.config.ts', icon: 'i-vscode-icons-file-type-nuxt' }
]
</script>

<template>
  <UTree :items="items" />
</template>
This lets you select a parent item without expanding or collapsing its children.

With virtualization Soon

Use the virtualize prop to enable virtualization for large lists as a boolean or an object with options like { estimateSize: 32, overscan: 12 }.

When virtualization is enabled, the tree structure is flattened, similar to setting the nested prop to false.
<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items: TreeItem[] = Array(1000)
  .fill(0)
  .map((_, i) => ({
    label: `Item ${i + 1}`,
    children: [
      { label: `Child ${i + 1}-1`, icon: 'i-lucide-file' },
      { label: `Child ${i + 1}-2`, icon: 'i-lucide-file' }
    ]
  }))
</script>

<template>
  <UTree virtualize :items="items" class="h-80" />
</template>

With custom slot

Use the slot property to customize a specific item.

You will have access to the following slots:

  • #{{ item.slot }}-wrapper
  • #{{ item.slot }}
  • #{{ item.slot }}-leading
  • #{{ item.slot }}-label
  • #{{ item.slot }}-trailing
<script setup lang="ts">
import type { TreeItem } from '@nuxt/ui'

const items = [
  {
    label: 'app/',
    slot: 'app' as const,
    defaultExpanded: true,
    children: [
      {
        label: 'composables/',
        children: [
          { label: 'useAuth.ts', icon: 'i-vscode-icons-file-type-typescript' },
          { label: 'useUser.ts', icon: 'i-vscode-icons-file-type-typescript' }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          { label: 'Card.vue', icon: 'i-vscode-icons-file-type-vue' },
          { label: 'Button.vue', icon: 'i-vscode-icons-file-type-vue' }

  },
  { label: 'app.vue', icon: 'i-vscode-icons-file-type-vue' },

getKey

(val: TreeItem): string

This function is passed the index of each item and should return a unique key for that item

labelKey

'label'

string | number

The key used to get the label from the item.

trailingIcon
