Desperate to find solution that restricts users from typing anything other than letters, number as well as the following 3 special characters -_/ inside an input.
Actually, you cannot restrict the input other than what Bubble have, but you can use regex to validate the input value and avoir submitting for example.
I don’t know if there’s plugin that allow that actually. You may also consider using Toolbox plugin to add JS to input and validate the text entered by user
