We are using Sharepoint 2010 and have a simple task list with the assigned to field. It's linked to active directory and right now the only way to assign a task is to type the users login and hit the check name button or use the search field to seach for a user in AD.
I want to change this to a drop down menu with only a select list of names or distribution groups from AD. How can this be done? The goal is to create a task, select who it's assigned to in the drop down box, and when the task is saved, an email will automatically be generated to the person or group that was assigned the task. I dont want to have to use the default AD/Exchagne lookup field.
