Hello Gibson,
Thanks for reaching out with your questions. Let me help you with them.
The best way to change “Additional Fields” would be to create a template override. You can find more information about doing this in our Themer’s Guide. You will need to create a template override for this file:
wp-content\plugins\the-events-calendar-community-events\src\views\community\modules\custom.php
To hide that block from the front end you have 2 options:
Either create a template override for this file:
wp-content\plugins\events-calendar-pro\src\views\pro\modules\meta\additional-fields.php
(Possibly creating an empty file would be easiest.)
OR you can just hide that part with this css snippet:
.tribe-events-meta-group-other {
display: none !important;
}
Let me know if this helps of if you have any more questions.
Cheers,
Andras
