Selected value in accordion widget is not getting change the parent dashboard filter in Sisense Why?

hey MuznahM ,

The accordion Plugin design to Inherit filters from the Main Dashboard and not the Other way around. 
Below are the Objects which can be defined for the Accordion Plugin, according to the Technical Details in the Plugin page

Suggest to review several Alternative options such as:

• Use the filter from the Main dashboard and Inherit it for the Drill dashboard
• Using Widget filter in the main dashboard
• Include the widget in the main dashboard

Best Regards 

Assaf
