F4 / Value Help on a Read-Only Field in a WD app

Hi friends,

I am struggling to put up a F4 help on an input field which has been set up as read-only. The idea is to have the field as read-only, and allow the user to select any value from the predefined values using F4/value help.

Now, I get the F4 help working if the field is NOT in a read only mode, However, the moment I set it to READ ONLY , the F4 help vanishes.

Is there a way to have the F4 help associated with the field even when the field is a read-only ?

Thanks.
