Can anybody suggest an approach to add grid panel to the last node/children of treepanel. I want to append gridpanel dynamically, for reference i am attaching a link. Jsfiddle
I also require to hide the gridpanel in collapse of the treepanel
Simplest way is to remember your grid somewhere in your node component and then hide it on itemcollapse event.
