@c1junk , Hi
You can customise your form if you use the Wix data forms. With Wix form, you are limited with the options(limited amount of forms you can create with ascend free plan). And you can create unlimited triggered emails for free if you use Wix Data form. So I do recommend using Wix Data forms. If you are good at coding, you could also create your form using code(no datasets). If you are going to use Wix data forms, I can help you here. But if you choose to use Wix forms, you will need to contact customer care as this forum is for Wix corvid topics only.
