I want to highlight the text box after its filled Automatically? is it possible?

Ok Found it i want to highlight the text box after its filled Automatically?

is it possible?

Yes it is possible with a workaround.

First I have set the read-only text box to "hidden" and added 2 form calculation widgets (one to be shown when the text box is filled, and the other one to be shown when the text-box is empty):

Then I linked each form calculation with the read-only text box:

I set up a condition that if "text box" is filled then show "filled form calculation". Another condition that if "text box is empty" show "empty form calculation":

Finally I injected the following css code:

#input_6

{background: red;}

You can try and clone the test form:

Let us know if further support is needed.

Thank you

By the way you can change the "red" value in the css code for a hexadecimal code of your preference. You can see more details here.

#input_6

{background: #3b6ccd;}

Thank you
