Equalize Height Stacks
You can only use Equalize Height with a total fo 4 stacks. One of them must be the columns stacks (2 or more columns, it does not work with the 1 column stack).
You must use this in conjunction with any of these 3 stacks:
Price Table Stack
Jack Stack (Non-Foundation Stack)
This setting must be checked on BOTH stacks for Equalize Height to work. We have had some reports of people checking this on only one of the stacks or using it with stacks that do not have this option added, and it can cause issues with the mobile menu.
Now go forth and make your websites great!!
