I had this problem in previous versions. I thought it was fixed. Work around: Put multi pick list field in separate field editor. Put that field editor in a wrapper. Put a red boarder around wrapper.

Matt,

How is the multi-picklist set to required? Are you using a validation rule or some other way?

Thanks!

It’s set as required in the skuid pagebuilder. It’s not required in SFDC.

Matt,

Hmm, that’s odd, I’m able to see the typical red outline if I set a multi-picklist to required. Do you have any custom CSS that could be messing with it? 

Thanks!
Amy
