How to solve this.
You can’t use ColinTreeListView in a card view component, you can either use it with a Vertical arrangement or a Vertical scroll arrangement instead. 
You can try to add a vertical scroll arrangement/ vertical arrangement inside your card view and use it with Colin tree list view initialize block.Ir enable the UsCard property with the vertical scroll arrangement/ vertical arrangement to look like a card view ( unfortunately, you won’t be able to scroll as satated here
P.S: you need to add more information about your problem to be easier for others to help
