Compare with current date

I need to modify a dropdown when the current date is less than the date of another field, I tried to workflow, but without success. Someone have some idea?


That is not achievable via workflow. If you have some basic knowledge of javascript and PHP. Then you can do it via CustomCode in editviewdefs by including external javascript into it.
You can find an example of how to include javascript at modules/Accounts/metadata/editviewdefs.php

Thanks for reply!! I already solved the problem, I created a workflow to compare the dates and am updating the value of the workflow compare date through a scheduled event on mysql!!
