I've got a modern drop-down control that I'm using to navigate between screens on my app. I'm using a variable to store the items that are displayed in the drop-down menu.

formMenu = [Home, Screen1, Screen2]

I want to set the defaultSelectedItem on the drop-down menu for each screen so that it shows the title of the currently displayed screen OnVisible.

How can I reference a single value in my single-column table to use in the defaultSelectedItem property of my drop-down control?
