In my recent open data project, I created a single page report model with a sparse slicer. It’s a good trick for anyone who wants to make their slicer look a bit sleeker. Like any other visual in Power BI, Slicers also have many properties. By default, below is how slicer looks in Power BI, but I made few changes to make it look like the one on left, in a few steps.
Steps
Place the slicer on the report page
Go to Items in Properties, add a frame around items
Go to General in properties, update outline weight, I prefer anything more than 7 or 8
Change Outline color to your visual background or Report Page background.
