Example:
Field 1 drop down has 2 values
F1Value 1 = A
F1Value 2 = B
Field 2 drop down has 4 values
F2Value 1 = 1
F2Value 2 = 2
F2Value 3 = 3
F2Value 4 = 4
When I select A in Field 1 I want Field 2 to show only 2 of the 6 drop down values within the field (values 1 & 2)
How do I do this in a template ?
