Although not recommended we could still have more than 1 sidebar on a page.

The issue here is we could have more than 1 sidebar open at the same time.

For example - open sidebar 1 and have a button inside sidebar 1 to open sidebar 2. This would open sidebar 2 without closing sidebar 2.

This needs to be fixed. The fix would be is to close all other sidebars on the page when any sidebar is opened.
