The URL Parameters window shows the parameter and its value passed from the user interaction with Open positions by department widget in the current dashboard.
The Allow URL Navigation checkbox lets you enable/disable the auto-navigation to the dashboard with the URL parameters in separate browser tab.
To explore the sample functionality, interact with the Pie Chart widget titled, Open positions by department. Now, the URL parameter will be framed with the department column and the selected value. If the Allow URL Navigation was enabled before interaction, it will let you navigate to the linked dashboard along with the URL parameter passed applied as filter.
