Thank you – I have added this to the functions and plugin – I switched from post category search to a custom post type / taxonomy approach. I noticed that I don’t have a multi-select dropdown option though – only multi-select/search option. Is there a way to apply a multi-select dropdown? Also, will/can the default view be to show all assets initially?
I also noticed that the main category doesn’t seem to filter back after selecting the sub-category. I only have one item in place now, but I would expect that to show for both the parent and sub selected.
