Is there any way to add a widget zone for the ajax filter? I will do the required css changes for my new placement.
EDIT: I found the file "SupportedWidgetZones.xml" in the folder SevenSpikes.Nop.Plugins.AjaxFilters. This worked fine after a rebuild of my solution.
Yes, this is the correct way to add a widget zone.
If you want to add a specific widget zone only for one of your themes, just go to the Ajax Filters plugin folder > Themes > YourTheme and add a file AdditionalSupportedWidgetZones.xml and inside it add the specific widget zone(s).
Once you change the working theme from the administration, you will see the widget zone in the drop-down with available widget zones.
