New List Slicer lacks basic functionality the existing "old" slicer has?

[sasdfasdfsad]

The new List Slicer is not able to be reformatted to be a drop down list.

This limits its value as space is always at a subtantial premium.

Additionally, there does not appear to be a way to change the expand/collapse icons.  They are the carrots > and v instead of the boxes with the + and - in them.

One nice benefit is the new List Slicer does appear to hide additional blank columns in a hierarchy, which is unfortunate the existing Slicer does not support this feature.

Are there any plans to merge the two or update the features to have parity?

Hi @sasdfasdfsad ,

Thanks for raising this. You're correct that the new List Slicer currently does not support dropdown formatting or custom expand/collapse icons like the classic slicer. This is expected behavior, as the new visual is specifically designed as a "List" slicer and does not include dropdown functionality by design.

That said, the new List Slicer introduces several enhancements over the traditional slicer. These include the ability to restrict selection to only the last level (leaf nodes) in a hierarchy, which can help limit user selection to the most granular level. It also adds new formatting options like Label and Image, allowing for more visual customization. You can now format each field in a hierarchy separately using the Series dropdown, and an Advanced toggle has been added to fine-tune Selection, Expansion, and Interaction states.

As of now, there hasn’t been any official announcement about merging the new and traditional slicers. However, since updates are being rolled out in stages and more features are being added to the new slicer types, it's possible we’ll see additional improvements over time.

Hope this helps. Please reach out for further assistance.
