Hi, Peter.
Thanks for the screenshot. It’s helpful for whomever will do the customization for you. However, we cannot provide such in-depth customization help, per our Scope of Support / Terms.
We do provide documentation how to accomplish this via our Themer’s Guide and tribe_get_event_categories(), but because it’s theme-dependent sometimes and would need to be maintained over time as new versions are released, we do not provide it.
If there’s a code snippet you’d like me to put some eyes on or something else I can help you with, please update this ticket or create a new ticket if it’s a separate issue.
Thank you very much for your understanding.
If you need some coding help, you may want to ask your developer, your theme author, or reference our documentation and list of known customizers.
