Alignment alternatives
Left - All lists aligned to the left
Right - All lists aligned to the right (Sometimes works well with two selection bars combined on the top row. One right-aligned and one left-aligned)
Center - All lists as closed to the center as possible. (Leaves sides empty if space is available.)
Center Spread - All lists centered but with outermost lists pushed towards the edges. (Works well when you want to use the full screen width for one selection bar object with multiple lists.)
Stack - All lists on top of each other. (Works when using more than one grid height of the selection bar. Also good for smaller screens.)
