I am trying to create a floating toolbar (xtype: container) that has a small margin and is docked to the bottom of a main container. The main container would have a card layout, so I could place multiple views in it, all having the same floating toolbar. I want the contents of the main container to be visible behind the toolbar, and the toolbar and main container need to be interactive at the same time (i.e. not modal). Any ideas on how to implement this? I have tried quite a few solutions with no success. Thanks in advance for your help.
