thank you very much for your advices!
tell me please, how exactly I need to modify event-editor.php to include option for adding the new category front-end?
Thanks for your answer. Yes I faced a problem of front-end creation a new event categories. Whether it is possible to modify somehow a code, that the registered user could create new category passing the WP admin-panel using Submission Form?
Thanks!
but how can I «add category» front-end via Submission Form?
users need to add their own categories to the events
