Overriding plugin template files

Hi,

I’m quite new to wordpress and very new to geodirectory!

I would like to change the search bar (listing-filter-form.php file) without changing the core file which is of course is a bad idea.

In other CMSs I have worked with you can copy plugin template files across to your own template and override them. Can anything similar be done with Geodirectory?

Basically, my directory will only list businesses of one type and users will simply be looking for the nearest one to them. Therefore I want to completely remove the main search field so users are simply search for a location.

Thanks,

Jamie
