The TileList class can be used to display a list of cells in a grid format.

When the list is set to scroll vertically, the columnCount property is used to layout the grid. You can use the rowHeight and columnWidth height properties to set the dimensions of each cell. You can use the cellPadding property to set the padding between each cell.

The following image shows a TileList instance.
