Description - Any validation possibilites for entered values into custom fields would be great.
Why is this feature important to you - At the moment there is no possibility to validate any entered values into fields. We cannot validate, if e.g. a valid email address, or url was entered, also for date fields it is not possible to define, e.g. that the allowed choices have to be after a specific date,...
How would you like the feature to work - RegEx would be fine
Current Behaviour - no validation
