So I need help thinking of a way to solve a problem.
I have a drop down that I need to change the options of and I would like to keep backwards compatability.
As an example I have a drop down with options A, B, C, D. I need to change the options of this drop down to A and E. The problem is that for all past requests in my application that used the first set of options (A,B,C,D) the drop down should show with the old set of options and all requests that use the new set of options (A,E) the drop down should use those options.
Most of the time the old options (A,B,C,D) will be shown in a drop down that is read only. How can i acheive this?
If I need to explain more please let me know.
