Input – onchange event?

Should be, without having to do anything specific to the CMB2 code. Just enqueue your own js file and use jQuery.on() with it and a selector that targets the intended input field.

I didn’t even know this was possible without hardcoding! Saved me a lot of time.

Keep up the good work, CMB2 is excellent.

You’re welcome, and thank you ??
