I am trying to configure widgets to go into a custom sidebar and show in sidebars that are on an archive i.e. all category archives. The problem I'm having is when I select the button labeled For Archives nothing happens. When I inspect the element in chrome browser I can see there is a class of "closed" applied to the hidden container. If I change the class to "open" then the panel is revealed so I can choose my options. There are no errors in the console. This behavior happens on any custom sidebars.
