Is there a way to append a drop down list with names from several forms

Is there a way to append a drop down list with names from several forms submitted over time? I need to populate a list of people that have complete a form using the first and last name element and signed the submission but then I want the first and last name from those forms to popular the array from the drop down menu.

To clarify, do you want to populate the dropdown option using the URL parameters?

Unfortunately, this is not possible. You may only populate the selected option in the Dropdown but it is not possible to populate the dropdown option list with values.

dropDown4={dropDown}

Hope this information helps.
