@unleaded: Real nice snippet,
ddTree, to use in conjunction with a TV - just follow the instructions to get going (I quickly tested on Evo 1.0 as well and no issues found). The snippet just returns the ID of the page though, so bear that in mind - although a simple hack would get the output be like: [~1~]
Now, this would render the dropdown, but wouldn’t allow you to enter external URLs - so if you needed external URLs, you’d possibly need a second TV for entering an external URL and have a snippet on the frontend to detect which TV should be rendered.
