My apologies for not making things very clear. here is the scenario:
I have got drop-down for field religion and i have entered few items and one of them is other so upon clicking other, it will change state of Text Input to Normal and user will be able to type in. Now form will take value from either drop-down or text input depending on user selection. At this point my question is: do i need to put drop down and text input in one group so form will take valur from either control for one field?
