StackPanel Toggle

[Hossein]

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

Thanks,
Hossein.

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

@Rogelio,

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

Thanks

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:

@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?

Thanks,

I took a look at StackLayoutPanel (StackPanel is similar), and it doesn't
have a "hideWidget" method, only a showWidget, which would have enabled us
to implement the toggle on the headers by adding a ClickHandler on the
Header widgets for instance.

So the only way I see to do what you want is to extend this class or
rewrite your own version so that it either has a "hideWidget" method that
hides any widget on demand (by its index for instance), or change the
private showWidget method so that it doesn't ignore when a header is
clicked and already selected, and instead hides it when selected/clicked
again. See line 668 here:
