Disable Input in String Widget Programmatically

Hi all,

I’m working in Knime Analytics Platform 5.5.1
Now String Widget doesn’t read/use the css in flow variables but it’s possible to customize look and feel of all Web Portal KNIME WebPortal Administration Guide

This is ok, but read css in a single node can be useful to disable the input element only when I want. (think about a form where you are only a viewer)

Is there another workaround that I can use?

Thanks,
Best
