David Eldersveld builds out a Power BI accordion filter:
The Power BI custom accordion relies on Bookmarks and Buttons as key elements. I’ve only created two categories in my accordion. I’ll be honest–it’s probably more work than it’s worth to keep track of different buttons due to positions as well as what’s visible or hidden for each bookmark. The thought of expanding to three categories is a bit daunting. Why is that?
Read on to see why (hint: combinatorial explosion).
