Changing fields

I would like to be able to change existing fields into drop-downs or into a field for entering phone numbers.  I do not see where it can be done.  Right now one of my fields is text and there is an advanced option that says "validation".  I set it to numeric to force users to enter numbers. I see a masking field there as well. However, on another field when I click on the field, there is no such option available.  I do not see any place to specify if the field is a phone number or if it is a date, no do I see an option to enter a drop-down field, etc.

ireI have checked your form and I can see that both the fields used in your form are different. That's the reason there is a difference in the options. Please find the screenshots below:

When I check the Dancer's Age field, I can see that this is a Short Text Entry form element.

On the other hand, if I check Contact Mobile No. it is already a Number form element. So that is the reason there is no validation in that form element as it is a number field.

For a drop-down field, please use the Dropdown form element.

Feel free to reach us in case you have any further questions.
