- Allow the form builder to create fields that accepts only numbers.
- Form Builder
- Future calculations will be possible with fields that only accept numbers.
As a form builder, I would like to have a field that accepts only numbers, so that users can only fill it using natural numbers.
1. Provide a feedback for the form user warning that the field only accepts numbers (in case the user wants to use a non-numeric value);
2. Do not allow the user to type letters and strings
3. Show message: "This field does not accept letters, type just numbers".
