Best way to add a selectable parameter to dashboards?
My approach in my head is to create an HTML widget at the top of the page with a dropdown list, and have it add a querystring to the page for that param (refreshing the page, unless that can be avoided). So if they chose "1" from a list, the url of the current page would be appended with ?myParam=1.
Is there a simpler, more elegant way of doing this, perhaps?
The benefits of doing something like this include not re-creating the same dashboard with different variables, letting the user quickly switch between views, and not cluttering the menu up with 50+ versions of essentially the same dashboard. I would pursue this for any one of those reasons, let alone all of them.
