With the new ListControl item in the screen design, how do I set the options?

When I add something to the String property it shows up in the dropdown, but I can't seem to figure out what the delimiter is for it to split the string into multiple dropdown options. I have tried using a , and ; with and without quotes around each options.

Which Screen are you playing with ?

I’ve created a screen from the blank template and added a list control component.

Try using a straight up and down bar  |        Between | your | options a space may or may not be needed. Hope this does it for ya! Fyi there is no scripting behind this screen unless you have created your own, you have use a default screen and modify from there.
