Hey Max,
1. Any of your event categories will be accessible via: http://www.yoururl.com/{events_slug}/category/{category_slug}/ – you can create links to these from the WordPress custom menus pages or manually.
2. Unfortunately this is not easy to do. For now I would suggest trying to rewrite your URL’s via PHP, plugin or .htaccess if you need this…
3. If you need to echo all categories you could use something like:
$terms = get_terms("tribe_events_cat");
$count = count($terms);
if ( $count > 0 ){
echo "";
foreach ( $terms as $term ) {
echo "slug . "'>" . $term->name . "";
}
echo "";
}
I hope that helps but let me know if you need anything else.
Cheers,
Jonah
