You can put the field on the Skuid layout twice and Mark one read only. Then you can put render conditions on each of the two duplicate fields so that only one of them shows at a time. The render conditions can be based on the value of another field.

Thanks, Raymond for the help! I just realized I left out that I was curious about routes that used snippets and custom field renderers. This also works, and was just looking for other options and miss a crucial part of my question! Thanks, Jeff

Jeff.  At the field level you conditionally enable a field (more than just rendering). Make it “disabled” for some status values, and “enabled” for others.  I believe this will get what you are after.  

This is better than mine… You win this time…

Thanks for the tip Rob! I hadn’t used those options before!
