</div>Installation & markup
Include the local stylesheet and script once on the page, then place the component inside a data-xsh-ui root. The example above works without a build system.
<link rel="stylesheet" href="/dist/xshna-ui.css">
<div data-xsh-ui>
<!-- Add the HTML example above -->
</div>
<script defer src="/dist/xshna-ui.js"></script>Component API
Public classes, attributes and hooks used by this example. Keep the xsh- prefix intact.
| Identifier | Contract |
|---|---|
data-xsh-menu | Used by the example markup and component styles or behavior. |
data-xsh-menu-trigger | Used by the example markup and component styles or behavior. |
role=menu | Used by the example markup and component styles or behavior. |
role=menuitem | Used by the example markup and component styles or behavior. |
xsh:menu-open | Used by the example markup and component styles or behavior. |
xsh:menu-select | Used by the example markup and component styles or behavior. |
Accessibility & keyboard
Open with Enter, Space or Arrow Down; Arrow keys navigate items, Home/End jump, Escape returns focus to trigger.
Implementation note. Use a menu for commands, not for ordinary page navigation. Menu items must be actual buttons or links.
Interaction contract
Behavioral components use the shared delegated runtime; visual-only primitives rely on semantic HTML and CSS. Runtime controls emit bubbling xsh:* CustomEvents; bind application handlers to those events when server persistence, API data or navigation is required.
