APEX

What I'm trying to accomplish is to allow our users to be able to select common inputs from a select list and they need to make an input that is not common they would be able to enter it in on there own by typing it in.

Here is the set up… The user needs to tell the program how many months old a home mortgage is between 1 month and 360 months. Many times the number of months would be the same common choices (such as 24 months, 180 months, 360 months, etc.) but sometimes they would not be (such as 19 months). The select list would have about 8 of the most common ones but we would still need to have a way for the user to enter in their own if it was not one of these common ones.

Is there a way for the user to click in the box and enter text into when the value they want is not in the select list? If not, what would be the best alternative way to set this up?

I have seen some documentation on select lists where you can update them with an input dynamically but we do not to add more options to our select list as we could have just put all 360 months on the list in the first place however that would have been to large.

Any help would be greatly appreciated. Thanks Adam
