Interacting with a widget will bring the user to the configured dashboard based on settings.
'Pass-through Dashboard Filters' means that the current filters on the screen will be continued into the new dashboard.
Define Drilldown Settings:
You can define the drilldown option, When hovering over a widget with a drilldown enabled, the mouse cursor will switch from an arrow to a hand indicating that the widget has clickable functionality.
Note: If a drill down is configured, but a field is not specified under ‘When Clicked’, all clickable fields that would lead to a drilldown should have a pointer hand upon hover.
