I would like to prevent users from being able to submit a form where the selection hasn't been changed from its original state.
In the wireframe above, when the user sees this form, the original selected option is Option 1. Since the user didn't change the option, I disabled the Save button. If the user selects Option 2, the Save button will be enabled.
I'm worried that users would be confused as to why the Save button is disabled, but this may be the best solution to prevent them from submitting a form that has no changes.
Came up with a design that I thought could potentially solve the problem, but a developer mentioned that the disabled-looking text doesn't really make sense. May be better to get input from UX-ers!
