I’ve been messing around a little with the Vertical Nav stack, and I think I’m seeing an issue with how it’s rendered with a border. If you draw a border around it, you end up with some extra space between the last item and the bottom of the border, as in this screenshot:
I know I can change the styling so that the lighter border around the items blends into the background. That still leaves an issue if a hover bgcolor is used on the items, though.
Here are the settings I changed on both stacks shown in the screenshot:
Border Width: 1px
Round Corners: 8px
Fill Mode: Flexible
Flexible Width: %50
I hope this is all good info.
