[Confiform] Compare 2 checkbox groups and change color if not matching

[Mike vD]

Hello all,

I started exploring Confiform today and ran into some desired functions that I have not been able to resolve myself, so I'm going to turn to the community for tips.

What I have:

• 2 field definitions with the same Checkbox group of 5 entries. Let's call them fields A and B, and the checkbox entries 1, 2, 3, 4, 5.
• A table with 2 fields based on the above definitions

What I want:

I would like to have the B field in the table change color if does not contain the same selected entries from the checkbox as in field A.

Example:

A   B

1   1

3   3

4   4

= no color change needed

A   B

1   1

2

4   4

= B field needs to change color

I have tried the Confiforms Rules for Fields (CSS) macro for field B where I configured it to -

!A:[entry._func.asEntryRef(entry.B)]

But this only works if B field is completely empty and the other is not. It also changes the color if B not empty but A is, which is an undesired side effect.

Is there a way to get it to function the way I want?
