  <p>I think that to output the result used a list of AnAction or custom analog. I'm interested in how to add the text to the right (example: New, Goto Goto by Name Actions, File, Goto by Reference Actions).</p>
  
  <p>In my plugin I use ComboBoxAction with DefaultActionGroup which have list of AnAction.
  I want an element in this ComboBoxAction to look like as on screenshot above that is:
  Icon Text RightText.</p>
  
  <p>Here is my ComboboxAction and where highlighted in red I want to add some text</p>
