I have controls on my screen that I would like to update based off of choices made in a dropdown list.

I have found a lot of literature on indirect tag binding using buttons etc.

What is the best way to choose an option from a dropdown list, and it update the controls on the screen based off of my choice?

Here is my indirect tag binding

Monarch/Asset {1}/Measurement/CURTF

why not just bind the selected value of the dropdown to your indirect binding?

Monarch/Asset {1}/Measurement/CURTF  
{1} = event.source.selectedValue
