How to set HeaderItem on the left side using VerticalGridView like Android TV Home Screen

问题

I am very new to Leanback Libraries. I want to develop Android TV home screen, where the CustomHeaderItem will be on left side and for each HeaderItem there will be one ListRow and instead of BrowseFragment, i want to render whole things on VerticalGridView. Like below picture.

To achiveving this, i tried to keep an ImageView inside HorizontalGridView and passing null value inside HeaderItem cunstructor. And the above things i rendered inside VerticalGridView. But while doing so, am not able to focus on ImageView.

How i will achieve the above scenario or where i am going wrong ? And also, How to stop header transition inside BrowseFragment ?

Thanks in advance :)
