    Class UIDropdownTool

    A toolbar tool that renders a trigger button and a dropdown panel.

    Items can be supplied via the items input (takes priority) or as projected content. Read the selected item id via the selectedItemId signal on the itemRef after a toolAction event fires.

    <ui-toolbar (toolAction)="onAction($event)">
      <ui-dropdown-tool id="insert" label="Insert"
        [items]="[{ id: 'table', label: 'Table' }, { id: 'image', label: 'Image' }]"
      />
    </ui-toolbar>
