Hey Yann!
Thanks for stopping by โ funny enough, we actually just addressed another user who wanted to remove the State/Province field. I’d recommend checking out my reply in that ticket, which you can find hereย โ https://theeventscalendar.com/support/forums/topic/event-submission-form-remove-dropdown-list-of-us-states/#post-905401
Let me know if that ticket is useful, or even addresses what you’re trying to do.
To remove the currency symbol option, follow the same steps in that ticket I linked to above. The only difference is that instead of looking in /community/modules/venue.php, the file you’ll want to duplicate and then modify is /community/modules/cost.php
Best of luck with your customizations! Let us know if these instructions get you a good start with things.
