I have a splitter with a listbox filling one of the panels. If I set the listbox to 100% height and margin-top of 5px, it looks correct… until I select an item in the listbox, where the listbox then jumps to fill the entire panel. Is this a bug within Splitter or ListBox? I have a jsfiddle that demonstrates the bug :
The jumping happens whether margin is set, padding is set, a spacer div is placed above the listbox; I’ve spent a full day trying to figure this out, and at this point, I’m convinced it’s a bug within either Splitter or ListBox
