ArcGIS API for Javascript dependent drop downs

[JacobTodd2]

I am currently working with ArcGIS API for Javascript 4.3 and I am having issues with creating dependent drop downs as a means of filtering multiple fields. For instance, in the following Feature Service: Layer: states (ID: 3) , I am wanting to have one drop down that is populated by SUB_REGION and then another dependent drop down that is populated by STATE_NAME based on the first drop down's selection. I am fairly new to this so any suggestions or samples would be greatly appreciated.

Jay,

  Nope you do have an issue with your requires. You have 

ScaleBar, Attribution,

in your require vars but not in your require array.
