You're right that list properties in Mixpanel user profiles can be truncated in the UI. Based on the knowledge sources, there isn't a direct way to view the complete list property directly in the user profile page interface.
However, you can validate and view your list properties through these methods:
1. Use the Events view - You can find the user in Events and inspect the complete JSON payload of events that contain the list property. In Events, you can toggle "JSON mode" to view the complete JSON object Mixpanel received, which would show the full list property values.
2. Use the Mixpanel API - Since the UI has limitations for displaying list properties, you can access the complete data through the Mixpanel API.
It's worth noting that according to the documentation, list properties have specific limits:
- Event Property lists: 8KB
- User Profile Property lists: 256KB
- Each string item in a list is limited to 255 bytes
Also, the documentation mentions that "Editing of list properties is not supported directly within the Mixpanel UI. To modify list properties, you must use the Mixpanel API or one of our SDKs." This suggests that the UI has limited support for displaying and interacting with list properties.
Debugging documentation recommends using Events to inspect the complete data that Mixpanel has received.
