Re: StackPanel Toggle

@Rogelio, Thanks for your input. Please see attached animated gif.
It uses StackPanel. However, Stackpanel, by default opens-up the 1st panel. What I like to do is to be able to toggle and expand OR collapse (e.g. User Interface panel). 

So, what you are saying is that I need to overwrite the default behavior?

Ok, I forgot about the StackPanel, which already does what you want, except you have to click on the header of each "stacked" panel, so I assume what you want is to click on the "body" of the panel (?) or add the ability to open multiple panels at the same time (?). I don't think StackPanel (or better, you should use StackLayoutPanel), support either of these two capabilities. To create that behavior, see if you can extend and overwrite the default behavior of StackPanel, otherwise, you might want to consider other widget libraries such as DominoUI which already has a Collapse component that supports multiple subpanels to be opened at the same time for example. I don't know of any widget that supports clicking anywhere to collapse/expand:

Thanks for your response. Please see attached. How would I create that behavior myself? Any help would be appreciated.

Of course you can always create that behavior yourself, or you could simply put your panel inside a DisclosurePanel:

Is it possible to toggle the StackPanel; i.e. clicking will open; and consecutive click will collapse.
