Submenus

Nest <l-dropdown-item slot="submenu"> elements inside an item to create a submenu — at any depth. A parent item shows a chevron, opens on hover, click, Enter or ArrowRight, and closes with ArrowLeft or Escape. Selecting a nested item fires the same select event on the dropdown and closes the whole menu (checkbox items keep it open). Use <hr slot="submenu"> for separators inside a submenu.

Min width

Set min-width="trigger" to floor the panel at the trigger's width — useful for select-like triggers (a date-range or filter button). The panel still grows with its content and stays matched if the trigger resizes while open.

Examples

Account menu

Use the header slot for a profile row, the prefix slot on each <l-dropdown-item> for a leading icon, and <l-divider> between groups for section breaks — <l-dropdown> tightens slotted <l-divider> spacing automatically.
