Is there a way on the phone number field to add a drop down or text box so folks can select what kind of number it is?

We would like to make mandatory at least entry for a phone number, but would like for folks to write in or let us know if that number is a Cell, Home, or Work.

I understand that you want to have an additional field to let you know the number entered is a Cell/Home/Work. To achieve this requirement, you may add a new dropdown box and position the field to align with phone number to the form in order to let the user to select the option as shown below.

I've also injected the following CSS code to the form to align the dropdown horizontally with Phone field.

#id_26, #id_27 {

padding-top: 33px;

}

Please see the demo form below :

You may also clone the form to your account to see how it works.

Hope this information helps. Let us know if you need any further assistance. We will be happy to help.
