Hiding layout cells

I would like to hide completely a cell when collapsing it (without any header to expand it).

I tried to hide header and to use setMinWidth and setMinHeight without success.
Is there a solution for this.

I answer to myself.
I found a solution using views on cells when loading page.
Content of cells (like form or tabbar structure) could not be loaded using JSON or XML to be sure content of a view is completely loaded before switching view.
If it helps someoneā€¦
