Hi! It would be super interesting (as well as necessary) to be able to create a property with field type "number" but that is only possible with positive numbers or to determine it from a number to another number. For example, in our case, we have a property called "number of courts" with the number of courts of a club, and right now it's possible to add negative numbers and numbers that are too high (unrealistic numbers for that property, and possible to fill in a form). In many cases there are problems, and it would be ideal to be able to limit that property so that they were, for example, only positive numbers or from 0 to 50. Thank you very much!
