Tree

TreeGitLab
Um componente de árvore para exibir e interagir com estruturas de dados hierárquicas.

Uso

Use o componente Tree para exibir uma estrutura hierárquica de itens.

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

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

Itens

Use a prop items como um array de objetos com as seguintes propriedades:

  • icon?: string
  • label?: string
  • trailingIcon?: string
  • defaultExpanded?: boolean
  • disabled?: boolean
  • slot?: string
  • children?: TreeItem[]
  • onToggle?: (e: TreeItemToggleEvent<TreeItem>) => void
  • onSelect?: (e: TreeItemSelectEvent<TreeItem>) => void
  • class?: any
  • ui?: { item?: ClassNameValue, itemWithChildren?: ClassNameValue, link?: ClassNameValue, linkLeadingIcon?: ClassNameValue, linkLabel?: ClassNameValue, linkTrailing?: ClassNameValue, linkTrailingIcon?: ClassNameValue, listWithChildren?: ClassNameValue }
É necessário um identificador único para cada item. O componente usará a prop label como identificador se nenhum get-key for fornecido. O ideal é fornecer uma prop de função get-key para retornar um identificador único. Alternativamente, você pode usar a prop labelKey para especificar qual propriedade usar como identificador único.

Aninhado 4.1+

Use a prop nested para controlar se a Tree é renderizada com estrutura aninhada ou como uma lista plana. O padrão é true.

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

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

        label: 'composables/',

            label: 'useUser.ts',
            icon: 'i-vscode-icons-file-type-typescript'
          }
        ]
      },
      {
        label: 'components/',
        defaultExpanded: true,
        children: [
          {
            label: 'Card.vue',

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

<template>
  <NTree :nested="false" :items="items" />
</template>

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

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

        label: 'components/',
        defaultExpanded: true,
        children: [

          }
        ]
      }
    ]
  },
  {

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

<template>
  <NTree :nested="false" :items="items" />
</template>
Quando nested é false, todos os itens são renderizados no mesmo nível com recuo para indicar a hierarquia. Isso é útil para virtualização ou para a funcionalidade de arrastar e soltar.

Cor

Use a prop color para alterar a cor do Tree.

<script setup lang="ts">

Você também pode desabilitar itens individuais usando item.disabled.

Exemplos

Controlar o(s) item(ns) selecionado(s)

Você pode controlar o(s) item(ns) selecionado(s) usando a prop default-value ou a diretiva v-model.

Use a prop get-key para alterar a função usada para obter a chave única de cada item quando um v-model ou default-value é fornecido.

Se você quiser evitar que um item seja selecionado, pode usar a propriedade item.onSelect() ou o evento global select:

Isso permite expandir ou recolher um item pai sem selecioná-lo.

Controlar os itens expandidos

Você pode controlar os itens expandidos usando a prop default-expanded ou a diretiva v-model.

Se você quiser evitar que um item seja expandido, pode usar a propriedade item.onToggle() ou o evento global toggle:

Isso permite selecionar um item pai sem expandir ou recolher seus filhos.

Com checkbox nos itens 4.1+

Você pode usar o slot item-leading para adicionar um Checkbox aos itens. Use as props multiple, propagate-select e bubble-select para habilitar a seleção múltipla com relação pai-filho e os eventos select e toggle para controlar o estado selecionado e expandido dos itens.

Este exemplo usa a prop as para mudar os itens de button para div, já que o Checkbox também é renderizado como um button.

Com arrastar e soltar 4.1+

Use o composable useSortable de @vueuse/integrations para habilitar a funcionalidade de arrastar e soltar na Tree. Essa integração envolve o Sortable.js para oferecer uma experiência de arrastar e soltar fluida.

Este exemplo define a prop nested como false para ter uma lista plana de itens, de modo que eles possam ser arrastados e soltos.

Com virtualização 4.1+

Use a prop virtualize para habilitar a virtualização em listas grandes, como um booleano ou um objeto com opções como { estimateSize: 32, overscan: 12 }.

Quando a virtualização está habilitada, a estrutura em árvore é achatada, de forma semelhante a definir a prop nested como false.

Com slot personalizado

Use a propriedade slot para personalizar um item específico.

Você terá acesso aos seguintes slots:

  • #{{ item.slot }}-wrapper
  • #{{ item.slot }}
  • #{{ item.slot }}-leading
  • #{{ item.slot }}-label
  • #{{ item.slot }}-trailing

API

Props

Prop Default Type
as'ul'any

The element or component this component should render as.

color'primary' "primary" | "secondary" | "accent" | "success" | "info" | "warning" | "error" | "neutral"
size'md' "md" | "xs" | "sm" | "lg" | "xl"
getKey (val: T[number]): string

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

labelKey'label' keyof Extract<NestedItem<T>, object> & string | DotPathKeys<Extract<NestedItem<T>, object>>

The key used to get the label from the item.

trailingIconappConfig.ui.icons.chevronDownany

The icon displayed on the right side of a parent node.

expandedIconappConfig.ui.icons.folderOpenany

The icon displayed when a parent node is expanded.

collapsedIconappConfig.ui.icons.folderany

The icon displayed when a parent node is collapsed.

items T
modelValue M extends true ? T[number][] : T[number]

The controlled value of the Tree. Can be bind as v-model.

defaultValue M extends true ? T[number][] : T[number]

The value of the Tree when initially rendered. Use when you do not need to control the state of the Tree.

multiple M

Whether multiple options can be selected or not.

nestedtrueboolean

Use nested DOM structure (children inside parents) vs flattened structure (all items at same level). When virtualize is enabled, this is automatically set to false.

virtualizefalseboolean | { overscan?: number ; estimateSize?: number | ((index: number) => number) | undefined; } | undefined

Enable virtualization for large lists. Note: when enabled, the tree structure is flattened like if nested was set to false.

onSelect (e: SelectEvent<T[number]>, item: T[number]): void
onToggle (e: ToggleEvent<T[number]>, item: T[number]): void
expanded string[]

The controlled value of the expanded item. Can be binded with v-model.

defaultExpanded string[]

The value of the expanded tree when initially rendered. Use when you do not need to control the state of the expanded tree

selectionBehavior "replace" | "toggle"

How multiple selection should behave in the collection.

propagateSelectboolean

When true, selecting parent will select the descendants. Requires multiple to be true.

disabledboolean

When true, prevents the user from interacting with tree

bubbleSelectboolean

When true, selecting children will update the parent state. Requires multiple to be true.
