I would like to modify the Jewelry Box theme so that the collapsible panel on the left can hold multiple widgets, but I'm having trouble getting started. Essentially the contents of the panel should look similar to those in the Dashboard theme with a little tab for each widget at the top of the panel, but also have the slide in/out properties of the Jewelry Box panel. I've looked at Dashboard and it has a gridlayoutmanager, but if I try to incorporate that, I lose the collapse mechanism. Am I going about this in the right way or perhaps there's another theme that will get me closer? Happy to take all suggestions! FYI, I'm using web appbuilder with an ArcGIS enterprise installation.
