Start Here

Start from the smallest working snippet, then move to interactive examples and the full API contract below.

Styled quick start

Copy this entrypoint first. It includes the imports required to get the component on screen.

svelte

<script lang="ts">
  import '@dryui/ui/themes/default.css';
  import '@dryui/ui/themes/dark.css';
  import { Tree } from '@dryui/ui';
</script>

<Tree.Root>
  <Tree.Item>...</Tree.Item>
  <Tree.ItemLabel>...</Tree.ItemLabel>
  <Tree.ItemChildren>...</Tree.ItemChildren>
</Tree.Root>

Import options

Root package

import { Tree } from '@dryui/ui'

Per-component subpath

import { Tree } from '@dryui/ui/tree'

Customize

Use the interactive examples to see common variants, states, and composition patterns before building your own.

Structure

Compound components always start with Tree.Root. Use this structure block to understand required wrappers before you wire state or styling.

Tree.Root
  Tree.Item
  Tree.ItemLabel
  Tree.ItemChildren

Compose

The full API contract lives here: props, CSS variables, and the public data attributes you can target when styling.
