Update disabled input to include readonly #552
Description
The disabled attribute in inputs is styled by Forge to appear greyed out. Would be useful to also include the readonly attribute with the same styling.
The benefit of the readonly attribute is that it still allows the form to submit the hardcoded value (say for example in a form which adds a value to an input based on IDs or something in the system; real-world example happens in Gladiator).
Whereas with the disabled attribute, any value in the input is not submitted via the browser as a value for the field.
