Rows in TTMSFMXScrollMenu

It would be nice, if TTMSFMXScrollMenu could be structured into more than one line.
If DefaultWidth is set, i can bult the horizontal selectionlist.
On scrolling, all lines have to scroll simultaneous.
An example for a two line structure
Item 1 | Item 2 | Item 3
Item 4 | Item 5 | Item 6
