Custom Taxonomy

Hi,

I would like to filter listings by a second Custom Taxonomy that is separate from my regular Categories but I don’t think this is possible with the plugin. (let me know if it is).

As a secondary option I can create a custom field but it needs to be multi-select so the list owner can choose multiple values.

Problem is I want this custom field to be positioned in the main advanced search bar but since its multi-select it can’t go in – I know it can be added to advanced search but I wanted to treat it front and center as a dropdown next to the regular categories.

Possible?

Thanks
