So according to the WAB documentation widgets within widget pools are controlled by/displayed within controller widgets, both defined within the configuration files. What I am trying to do is use two controller widgets (sidebar and header), each displaying/controlling a separate set of widgets. I am trying to configure this at the theme layout config level but without much success.
What happens is the config file will only accept one widgetPool item and both widget controllers will each load all widgets within than widget pool. I can't seem to figure out how to separate sets of widgets to display separately in the header and sidebar controllers, and each with different panel styles. I have played a bit with groups within the widget pool but that doesn't seem to work either - everything in the widget pool will still display in both controllers.
