Drop down menu

I want to be able to jump to window 2 when I select window 2 here… window 3 for window 3… ect…
I cannot figure out how to set this up…
I looked through event handlers and custom properties.
What am I missing here?

heres how I accomplished this event handler script:

value = event.source.selectedStringValue
system.tag.writeToTag(‘WindowStatus’, value)

It threw me off that I could not access this directly in the navigation tab.
