Hey Paul,
Thank you for reaching out and using us for your calendar needs! There are a few ways you can go about hiding/removing certain fields. The first option is our Knowledgebase article titled ‘Required fields for events submission form’.
The second option would be via a template override as explained in our Themer’s Guide. The file you’ll need to overwrite is /the-events-calendar-community-events/src/views/community/edit-event.php.
I hope this answer helps and please let me know if you have any more questions or comments. Have a great rest of your weekend.
Cheers!
