ListView within a Listview

Hi,

I need to display multiple rows in each ListView ItemTemplate, for example I've database table with following records (FieldName: Value):

Config: 1, Colour: Blue
Config: 1, Size: M
Config: 2, Colour: Red
Config: 2, Size: L

And I want it to display like this (content between ______________ is ItemTemplate):

Colour - Blue
Size - M

Colour - Red
Size - L

It's almost like grouping (in this case by Config), but I don't want group headers and I also want ItemTeplate to be selectable. If I use grouping then I would get 4 rows instead of 2. I also don't need nested list to be scrollable.

Is this achievable in Xamarin Forms?
