Currently I am working an android tv application project and my navigation panel is showing text and icon when it is in expanded mode like - 

[![expanded](https://i.stack.imgur.com/gMjzk.jpg)](https://i.stack.imgur.com/gMjzk.jpg)

When navigation panel is collapsed it showing a vertical bar with just color and no icons or something is showing.

But I am trying to achieve this kind of design when navigation panel is collapsed -

Now my question is is this achievable using leanback and if possible how can I implement it?
Any kind of hints, tips or reference will be helpful.
Thanks in advance.
