Hi Linh,
Thanks for reaching out!
Yes, the limit is set to 200 by default. You can change this however by adding the following snippet to your functions.php file:
/* Tribe, set new limit to 300 organizers in filterbar */
function tribe_fb_change_organizer_limit ( $limit, $organizer_ids ) {
return 300;
}
add_filter( 'tribe_events_filter_bar_organizers_limit', 'tribe_fb_change_organizer_limit', 10, 2 );
Keep in mind that raising this limit may slow down the loading time. Let me know how that works for you!
Thanks,
Jennifer
