Add hierarchy to drop-down list filters for a more custom interactivity.

Similar to a cascading filter set, except directly on the dashboard canvas.

Specific Example:

I have a dashboard that displays employee hours and it breaks down groups by different categories such as title (e.g. Associate, Senior Associate, Manager, etc.) and class years. The drop-down list filter allows business leads to filter down the timecard information based on the employee group they would like to see, but using one filter will affect the other. I would like to see some sort of hierarchy that essentially filters down class year based on the title selected, but choosing a class year does not filter titles.

Imagine a business lead selects a title group then a class year to look at a group of employees. Now they're interested in another title group. They would simply use the drop-down filter to choose another title group and the class year filter would just clear out. The business lead could then choose another relevant class year, or just look at employees of all class years in the specified title group.

More Generic Use Case:

Say you have 3 levels of logical hierarchy, 1-parent, 2-child and 3-sub-child, and, we are looking at camping equipment. The idea would be to have the ability to clear out the child filters based on what is selected in the parent. So, say filter 1 is camping equipment, and on the 2nd drop down it lists tents, pots, etc. If you choose tents, this reveals the list of kinds of tents on the 3rd list (1 man tents, 2 man, etc.). Now, if you choose something else in the parent, the expected behavior would be to clear the child filters then you can filter your next choice.

I think this could add more interactivity into dashboards and possibly be more intuitive for non-technical business users, who might get confused by filter behavior when there are more filtering options. My actual dashboard has four categories you can filter, and it could easily confuse a business user as to why they can't select more options in any one filter when others have been set. Clearing out all of the filters every time could be frustrating and discourage these users from interacting more with the dashboard.
