Field appear based on Multiselect

Hi,


Is there a way to have a field appear based on value(s) selected in a multiselect field?

For example, I have multiselect "field 1" that has selections A,B,C,D

I want field 2 to appear if B is selected in field 1

I want field 3 to appear if C is selected in field 1

I want field 2 and 3 to appear if both B and C are selected

Thank you,

Andrew
