select widget with OptionList process variable
I want to display a OptionList text variable in a Select widget. It seems to be quite simple but I have a couple of questions. I found an example here but with a JSON object instead of an Option list variable.
Next things I did in Studio 7.1.5 community.
1) Create a Option list variable (process variable) with a list of text options. called: "cars". ie.
2) In a Form UI 7.1.5, I create a link to a process variable called "CarList:
3) In a select widget I configured:
3.1 Available values = CarList
Which values should I put in "Display Key" and "Returned key" ?
Thanks in advance
