Hi,
hmm can you let me know where you would like to have this functionality? I am looking at the Add Items pages on your site and it already allows selecting multiple categories?
On the marketplace page for customers 🙂
Ohh ok i see :). The way you have it setup right now it is not really possible to select multiple categories i am afraid, as the category links in the left sidebar only link to taxonomy page.
To allow searching by multiple categories you would need to install a Search By Category snippet https://github.com/simpliko/wpadverts-snippets/blob/master/search-by-category/search-by-category.php it will add a multi-select dropdown to the search form. This will allow searching by multiple categories at once.
The snippet you can install by either pasting it in your theme functions.php file or by installing as a separate plugin (as explained here https://github.com/simpliko/wpadverts-snippets/ at the bottom of the page).
