It would be very nice if multi selection works with drill down dimension.
1) I have field - City and field - Shop
2) I create drill down dimension with those fields with name "dFields"
3) I create treemap with dimension "dFields" and limit top 5 items
For now i see in this treemap visualization top 5 Cities, i can chose one City and it changes visualization to top 5 Shops for this City. But if i want that my treemap shows top 5 Shops for all Cities or for couple Cities, i cant do it with drill down dimension.
