That's correct, "American" is the category, but "Burgers" is a subcategory, so the map does not appear on that view by default. Technically yes you could make this change through modification of the theme, but it is not a setting within the Vantage admin dashboard.
Regarding how the categories are displayed, in the
Vantage admin you can control whether or not to display the subcategories below the categories in the menu itself, however clicking the category will still display the results rather than show a list as you describe. Again, this could be changed through customization of the default theme, but is not an option.
At this time there are no additional controls for the advanced search functionality. Eventually we plan to allow more options like with our
ClassiPress theme, where you can determine which custom fields are searchable.
By default, the only controls for that particular widget at this time is related to how many recent listings are shown and which sidebar to place the widget in.
Although I have seen mention of OIO Publisher in the forums, there is no confirmation from any members of the community who specifically state this as been tested and definitely works. AppThemes does not officially support third party plugins so we cannot guaranatee that all plugins will be compatible.
The theme is not encrypted, so you are free to customize the layout as you wish. We recommend the use of a
child theme if you are looking to modify the default theme, as this will prevent you losing all of your changes in the process of an update. You may also like to check out the
AppThemes customer showcase to see the kinds of modifications other customers have made to the theme. Thanks.
