Easily add a choice to a drop-down list especially when this needs to be done alphabetically.
Need: Have a dropdown field that makes use of a single list of choices to maintain and no longer have to complete form by form.
The forms will make reference to this single list to be updated.
Objective: administrative gain in terms of maintenance / ease of updating
Example, in our case, every time we add a site we must review and update 80 forms.
