Description

A trigger for a menu.

The ngMenuTrigger directive is used to open and close menus. It can be applied to any interactive element (e.g., a button) to associate it with a ngMenu instance. It also supports linking to sub-menus when applied to a ngMenuItem.

<button ngMenuTrigger [menu]="myMenu">Open Menu</button>

<div ngMenu #myMenu="ngMenu">
  <div ngMenuItem>Item 1</div>
  <div ngMenuItem>Item 2</div>
</div>
