Select more than one data in a drop- down

[Adolfo_Enrique_]

Hi, I need help with the following.
In my application, I created a form where one of the data that I must select are colors. I need to be able to select more than one color from the data that can be seen in a drop-down. Can someone help me do it if possible?

Change the column type to EnumList to allow multiple values to be selected.
