It takes a few seconds after a user is done typing in the multiline input for the conditional to go into effect when the max number of characters has been exceeded, but it still works. Also, you could consider limiting the number of characters on the multiline input itself… there is a checkbox for that on the Appearance tab of the element editor.
Thank you this solution works!
However, I have a problem and it is not updating real time. I have to click on the multinline before the condition applies
For example, I put in 1000 characters on the multiline, however, before it deactivates the button, I still have to click somewher on the multiline first
What do you mean by click on the multiline? If a user is entering text into the field, then they have already clicked on it. Sorry, I’m not sure what’s not working here.
