SPCascading drop downs

Mar 21, 2015 at 11:55 AM
I created two drop downs: Location and Department and followed instruction provided. Location is parent and Department is child drop down. On New Form, Initially, Location show (None) and Department show blank. Is this an expected behavior? I expect Department also show (None). If blank is a expected behavior, is there a way for Department to show (None) on function $().SPService.SPCascadingDropDown()?

It depends if the columns are required or not. If you look at them without the call to SPCascadeDropdowns, you'll see that when the column is required, SharePoint doesn't give you the (None) option.
