Dropdown Filter not Responsive

Hi Unity 

You may want to custom the width and length in drop-down option in slicer.

We can only custom the width of slicer without the length of drop down slicer.

Your demand is a good idea, while it is not supported to implement in Power BI currently.

You can vote up this idea for this function：Slicer auto adjust width
Or you can submit a new idea to improve the Power BI.
It is a place for customers provide feedback about Microsoft Office products . What’s more, if a feedback is high voted there by other customers, it will be promising that Microsoft Product Team will take it into consideration when designing the next version in the future.

Best Regards,
