Thanks for the response Jakub, just gave a couple of tests to understand the behavior liek you said.
i observed that what you said is true, but my exact requirement is to hide the interaction pane completely and show it on a button click or something.
But when i use toggle button it just pushes the new view half a way and it doesnt hide the Interaction window's case details completely until i click on Arrows to hide the interaction.
After i did hide the case details i relauched the view but its like the previous trail. Case details doesnt get minimized/hidden.
