Multi value parameter for Power BI desktop report

Hi everyone,

i am doing POC on Power BI report so quite new on this one. the problem i am getting is to create a multi value selection from drop down parameter for power bi report. 

I have created a data set from SQL query which is i am using as a parameter in the power bi report. When power bi opens, it prompt for the value from the drop down list which is populated with the data set. now here from that drop down i can choose only one value and my report runs perfectly fine based on that parameter but i want to enable this parameter drop down for multiple value selection similer in SSRS. please advice how can i do this.

In the snapshot below you can see in the drop down parameter list i can choose only one value.
