Custom field on Location

You could do it like with events or categories, as explained in the tutorials (see plugin site docs section).

Hi Marcus,
Thanks for your reply. I have searched Docs and tutorials, but I could not find the way to add attributes to Locations (or categories), could you please provide the direct link to the documentation you have mentioned?
We are researching plugins for a project and we are delighted with your plugin, but we need to have this covered before we purchase the license.
Kind regards,

have you try looking at https://wp-events-plugin.com/tutorials/ OR https://wp-events-plugin.com/tutorials/creating-custom-event-search-attributes/
