Foldable panels with overlay in extjs layout

Question

I use the border with two panels in the east and in the center as my elements, and by default, if I make the markup on the east panel, it will resize the center panel when it is expanded or reduced. I want to know whether it is possible to change this nature in such a way that when the east panel expands, it overlaps the center panel and does not share the total width. The image below may give some idea of ​​what I want to achieve.

thanks!

Answer 1

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