Hi Christopher!
Thanks for reaching out to us! 🙂
You can achieve that by putting the following code snippet into your theme’s functions.php file:
function show_all_categories_community_add_form() {
return 999999;
}
add_filter( 'tribe_events_community_category_dropdown_shown_item_count', 'show_all_categories_community_add_form');
This will set the number of categories to show before the “Show all categories” link. So putting a really large number is, in practice, the same result as showing all categories.
Let me know how this works for you.
Best!
Victor
