I'm working on a custom drawbylist widget and I have trouble with loading the map on the center pane. I need my custom widget to go in the left pane and the map in the center, like shown in the example below. I'm following the example below, as my baseline.
I have two issue, the tab is not showing up and the map is not in the center. Could you please help .( I'm running on a Tomcat server to load templates and json files)
