Is there formula syntax for viewport width?

Is there formula syntax for viewport width?

Use case:

I load certain models after render using the Skuid Page: Rendered Event.

I would like to add a branch with an IF statement to load or not load specific models based on the viewport width so I can load specific models for mobile vs. desktop.

Sorry Duane - there is not Formula Syntax for returning the current viewport width. There have been a number of snippet based approaches published here through the years that collect viewport on page load and update a UI Only field - which you then can use for the sort of branching you describe.

See this one:
