====Configuring the Parent Dropdown====
# Create a custom field of type '''Select One - Dropdown List'''.
# In the '''Predefined Options''' field, map the various lookup keys of your custom lookup data to the options you want to surface in the dropdown. In our example, our lookup keys span a range of 100 to 600, which with each 100 increment corresponding to a different university. Mapping the lookup keys in this way will allow the child dropdown we set up later to be filtered by the selected lookup key. For example, if the user selects "Totally Totes College" (with a lookup key mapped to 100), the corresponding child dropdown options will filter the custom lookup data by this lookup key and only returns return the courses available to that university.
