Setup Multi-Select Custom Field for Listing

Hi there,

I’ve recently purchased the PremiumPress Responsive DirectoryPress Theme. When setting up the fields for my listings I stumbled over this issue that might be easy to solve – yet I couldn’t figure it out.

I’d like to display a multi-select box to users with my own values (just like the category selection one). I got it to work with the checkbox input type, but due to my very high number of values (100+) this looks really awkward within the user form.

Please, is there a way you could add the multi-select box input option to the custom field setup?

Thanks & a big wave from Berlin/Germany,
Piet
