PUI.Layout (pui v1.0.0-alpha.28)

Reusable application shell primitives for documentation sites, dashboards, and other two-pane LiveView layouts.

The layout API is split into small components so applications can compose their own shell without inheriting opinionated navigation data structures.

Basic Usage

<.app_layout id="docs-shell">
  <:sidebar>
    <.sidebar>
      <:header>
        <div class="px-4 py-3 font-semibold">PUI</div>
      </:header>

      <nav class="p-3">
        <.sidebar_menu_item title="Getting Started" icon="hero-rocket-launch" href="/docs" />
      </nav>
    </.sidebar>
  </:sidebar>

  <:header>
    <.content_header shell_id="docs-shell" breadcrumb_current="Getting Started" />
  </:header>

  Content goes here.
</.app_layout>

Collapsible Navigation

Use collapsible={true} on sidebar_menu_item/1 when an item owns nested links. The submenu state is handled by the bundled PUI.Sidebar hook.

<.sidebar_menu_item
  title="Components"
  icon="hero-squares-2x2"
  collapsible
  expanded
>
  <:subitem>
    <.link href="/docs/button" class="block rounded-md px-2 py-1.5 text-sm">Button</.link>
  </:subitem>
</.sidebar_menu_item>
