I have a workflow that populates a Multi-Select Interface tool with field names available in the workflow. I want the user to select which fields they want to see on their output. How can I do this? In my example, if the user selects they want to see Red in the output, the second screen shot is what I'd like to see. I don't know how to tie the two together and from my mainstream workflow (simplified below) select a few required fields like Customer and Region and then only the fields the user wants to see which is Red. I've got a list of about 40 fields the user can select from to determine want end up on the output. ABSOLUTE BONUS if someone can tell me how a user can inform the workflow of the order they want the fields in on the output and I could work that into the workflow (which resides on our gallery).
