Hey Jordan,
Our Filter Bar add-on makes it easy for your site visitors to filter by Event Category (and many other ways).
You can also go to wp-admin > Events > Event Categories and then click “View” under each category to learn what each category’s link is. You can then direct your users to a specific category.
If you want to exclude one category, you’ll likely need to create a custom template. There is a guide here for that, and this thread should be particularly useful for your question. (note: you’ll want to add
'operator' => 'NOT IN'
To that query to exclude terms.
If you have any follow-up questions, don’t hesitate to ask!
Cheers,
Stephen
