@atidwel The previous post already provided the necessary answer, but I want to make you aware of a workaround that would work with the new widgets as well, until they get official suport for state-based formatting.
The state-based formatting modifies certain HTML attributes/css depending on the input value for a widget.
To achieve this you can use the CustomCSS mechanism and one expression. By using an expression with an input parameter (widget input value) that outputs a string (the custom CSS class name) you can set the CSS class for your widget depending on the input value. Hint: you can use multiple inputs, from other widgets, to set your Class.
