Minimal Vanilla HTML + JS

For a minimal custom implementation, use the same BEM classes and toggle aria-expanded and menu visibility. Full keyboard navigation and submenus require the script used by the Astro Dropdown component.

html html 
<div class="dropdown" data-dropdown="my-menu">
  <button type="button" class="dropdown__trigger" id="my-menu-trigger"
    aria-expanded="false" aria-haspopup="true" aria-controls="my-menu-menu">
    <span class="dropdown__trigger-text">Menu</span>
    <span class="dropdown__icon" aria-hidden="true"><!-- chevron SVG --></span>
  </button>
  <div class="dropdown__menu" id="my-menu-menu" role="menu" aria-hidden="true" tabindex="-1">
    <div class="dropdown__item-wrapper">
      <div class="dropdown__item" role="menuitem" data-dropdown-value="a" data-dropdown-onclick="myHandler">Item A</div>
    </div>
  </div>
</div>
<!-- Use the same init script as in Dropdown.astro for full behavior -->
