Hey Roland,
If you’re familiar with custom code, you can use our “Template override” system to make custom ticket forms and such, which is all described in our “Themer’s Guide” here → https://theeventscalendar.com/knowledgebase/themers-guide/
We can’t help with customizations, but that article is comprehensive and customizing the code is relatively easy if you’re familiar with it in any general sense.
Other than these methods, there are no default or options-panel-based ways to customize the ticket forms.
I hope this helps!
George
