Slicers with Multiple Values Returning Distinct Lists

Hi , Anonymous 

According to your description, you have a sliver , and you need to return a list of all "Title" values associated with the selected name(s) in the slicer.

First , in the measure we can not return a list , but we can define the list in the "var" as a parameter.

For your need , we can use the :
var _list = VALUES('Table'[Title])

This will retrun the current filter context's [Title] list.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,
