Showing only slicer data that have facts in Power BI (and other fun tricks)

As of this month Power BI finally supports filtering slicers down to only show rows that have fact data. Before the only thing you could do to achieve this was some workaround like: I described here where you filter down the dimension using a calc table. The other approach was to use Bi Directional cross filtering which would filter down the dimension table appropriately. This leads to performance issues though.

Now you can use a measure to filter down the slicer. If you take a scenario like below where we have sales that can be driving by promotions.
