Render complex attributes of entries. #86

Is your feature request related to a problem? Please describe.
Currently, complex attributes of entries (e.g. List, Dict) are not supported. "N/A" or "Complex Object" are being shown at the attribute slot.

Describe the solution you'd like
Since there is a limited and non-recursive type of complex object, it should be safe to implement a one level collapsable view for List and Dict. A user can expand the view to see the details of the List.

Describe alternatives you've considered
No
