Hey @ELOISA,
Thanks for reaching out.
We unfortunately can’t offer any assistance or guidelines on creating custom themes, templates, plugins, code, etc—we only provide technical support for our plugins as defined on this page ? https://theeventscalendar.com/knowledgebase/what-support-is-provided-for-license-holders/
The features you are trying to implement are possible, but would require many code customizations to implement.
So to implement the features you describe, you would have to write that custom code or hire a professional developer to do it for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
I hope this information is helpful—please let me know if there are any other issues or questions I can try to help with.
Sincerely,
George
