collapsible panels with overlay in border layout extjs

Question

I am using border layout with two panels in east and center as its items and by default if i make the east panel collapsible then it will resize the center panel when expanded or collapsed. I want to know if this nature can be changed in such a way that when the east panel is expanded , it overlays on the center panel rather than sharing the total width it. Below image might give some idea what i want to achieve.

thanks !

Answer 1

By default the panel is floatable, so just need to hide the collapse tool to achieve it
