Hi Bradley,
Thanks for reaching out!
There isn’t an out of the box way to do this, but you can do it with a small customization. First, you can copy the template for that page into your child theme by following these instructions. The template can be found at wp-content/plugins/the-events-calendar-community-events/src/views/community/modules/taxonomy.php. You can then add the following code to the template in your child theme, just above the foreach block on line 42:
// set default category
if ( 'tribe_events_cat' === $taxonomy && 0 === get_the_ID() && empty( $value ) ) {
$value = array(16); // Default category term ID
}
You’ll need to replace the ’16’ with the ID for the category you want to set as the default. You can find the category ID by going to Events > Event Categories and clicking on the category – it will appear in the URL (see screenshot).
Let me know how that works for you!
Thanks,
Jennifer
