Trying to use a Marketo form that would end up with non-selectable labels to help organize a longer picklist.
Functionality is similar to: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_optgroup
I did try to just put in a label like "DISPLAY|" but it still allows that to be selected.
Any advice is very much appreciated. Unfortunately (but not surprisingly), this was a request for a program that has to launch Monday so not a lot of time and I have a feeling this will end up being a custom form.
