How to Handle List Property Breakdowns in Mixpanel with Multiple Values

·Jan 14, 2026 03:58 PM·

Hi! I am new to Mixpanel so when I try to add a breakdown with List property. My row is displayed as (not set) when my List.length is > 1. Example i have a property of items. The value can be ["puma"] , ["puma", "nike"], ["nike"]. Breakdown can only recognise either single value of puma or nike. How can i cast the multiple value List?

Hi Prakarang I tried to reproduce your case and as expected, when property is a list, it renders as elements of the list in breakdown. When list is recognized as string, there will be 3 values in breakdown: ["nike"] ["puma"] ["nike", "puma"] I tried to cast this list to other types and never end-up with (not set). When you look at event body, is this 2 element list available?
