===Setting up Dynamic Dropdown Lists===
Custom lookups can be incorporated into dynamic dropdown lists using the parent and child relationship between data. After uploading a CSV for your custom data, you can set up a series of parent and child dropdown lists that can further filter user options based on previous selections. To set up a parent dropdown list, create a custom field of type '''Select One - Dropdown List'''. In the '''Pre-Defined Options''' field, map your dropdown options to the lookup keys you chose for your custom lookup. For example, a custom lookup for course registration may have a lookup key that uses 100 to denote freshman courses, 200 to denote sophomore courses, etc. When the user selects a course year from the parent dropdown, their options for the child dropdown will be filtered.
