Panel Tools Dropdown Menu

[JLKoszarek]

The Panel has Ext.Tools array which is great for adding button to the Panel's toolbar. Its added as a json array of objects as so:
<Panel title="Custom Tools w/ iconCls"
tools={[ {iconCls: 'x-fa fa-wrench', handler: toolHandler }, ... ]}/>

Is there a way to add a dropdown menu to this toolbar? E.g.
<Panel
tools={ [ { iconCls:'x-fa fa-wrench, children: [ {another menuitem}, {another menuItem},...]}} ] }
/>

Have the handler show a menu.

Entails coding.
