Conditional Formatting | WordPress.org

Hello @michaelrieder

You can use a calculated field as an auxiliary to modify other background fields at runtime.

Insert a calculated field in the form (you can hide it by ticking a checkbox in its settings) and enter an equation similar to the following one:

(function(){
let color = IF(fieldname1|r == '', 'red', 'white');
getField(fieldname1|n).jQueryRef().css('background', color);
})()

If you want to modify the background color of the input tag in the field instead of the field as a whole, the code would be:

(function(){
let color = IF(fieldname1|r == '', 'red', 'white');
getField(fieldname1|n).jQueryRef().find(':input').css('background', color);
})()

Best regards.
