how do you create a parameter list drop down in power bi?

Question

I have always been able to create drop-down list parameters within SSRS that allow the user to dynamically filter their reports based on one or more values selected from the drop-down list box of multiple values.

Translating now over to Power BI I cannot find any documentation to achieve the same functionality.

Answer 1

This is a completely different feature in POWER BI.  So for that First 

We have to create a slicer visual and, as you've already discovered, set it to Dropdown type using the upside-down carrot icon on the slicer header.

It is already by default (dropdown list is multi-select).  Hold down [ctrl] while making multiple selections. However, you can control Multi-Select behavior under the 'paintbrush.' When the visual is active, click the paintbrush icon under visualizations,

For managing your slicer we need to expand 'Selection Controls'.
