I need to add a multi-select field within my incident and service request forms.  I searched these forums and found another person had asked for the same feature 2 years ago, but did not get much of a response other than "we'll add it to the feature enhancement list."

If a multi-select option is not available, is there an option to place custom code within a form? 

For example, could I add a button that launches a popup that is hosted outside of ServiceDesk Plus, one that includes the ability to select multiple options, then save those options as text into a field on the form?

Thanks in advance!
