How to require a DropDown selection

[llarge]

Hello, I have a form with 2 fields that users need to input some data. Those fields are required. The 3rd field is a drop-down. The issue is that I cannot select required unless I change that field to an editable field. Once it's an editable field, then the user can type and change the drop-down data. I know I could probably use my button program to prompt the user to fill in something there if it's empty, I just wish there was an easier way to enable this behavior on the front end. Is there an easier way? Maybe this is more of a feature request post, let me know what you all think.

Sorry, I am confused. Are you saying that the user is allowed to type in an option in the combo box that is not part of the results set of the combo?

Let me clarify.
The current form is the screenshot I added in the post. The first 2 fields are required. the dropdown is not required. I WANT it to be required. I can not select required as an option unless the field is "Editable" on the form. If I selected Editable, users can then edit the values which nullify the point of the drop-down.
How do a make a field required if it is not editable? that sounds like a silly question, but once a field is transformed to a dropdown in a form, it is technically editable but NAB is not letting me select the same options that an editable field would have.

Marking a field as required would not make sense if the field is not editable. I am still not clear why not mark the combo (CONDITION_INPUT) as a required field if you want it to be?
We may need to get on a quick call to discuss as I feel I am still not understanding the issue entirely. Send out an email to support@cnxcorp.com if you would like to discuss.

Solutions. Just click the editable option on a dropdown field. I was getting worried because once you do that, a user can type in whatever they want to the field. However, as soon as you click off the field, it snaps back to one of your values and clears whatever the user typed in.
