I have a situation where a rendering could use a set of customization buttons that are all related. Rather than filling up the rendering's edit frame, I'd like to add a button that can expand into a dropdown similar to how the datasource menu expands to show additional commands.
Is there anything built in that would allow custom buttons to open submenus of buttons?
Alternatively, is there a component that can be used in a custom command to open a custom dropdown that contain buttons to trigger different commands?
Note: I'm aware I can add buttons to the datasource and more dropdown menus, however this would be inappropriate for the buttons that I'd like to add.
