Question : FM - Limiting a Second "Sub-Type" Drop-Down Box by Choice in "General Type" field

How do you limit the choices in a second "Sub-Type" drop-down box by your choice in the first "General Type" field.  For example, choosing "Utiility Companies" in the first general type field would only show Electric, Heating, etc in the second field whereas choosing "Retail" would show Nail Salon, Furniture Store, etc.  Looked it up in FM help, but the section on drop-down did not mention anything.  Thank you.

Answer : FM - Limiting a Second "Sub-Type" Drop-Down Box by Choice in "General Type" field

I put this sample together that might help.  It uses produce, fruits and vegetables.  The basic explanation is you have a self join to the produce table on the group and use the relationship to display the resulting of produce in that group.
