Here is an example that I had created that uses a parameter to select dashboards as well as the link that shows you how to set up a sheet selector.
Hope this helps,
Not dashboard. But sheet selector can be done. That will look like dashboard selector.
Can create soomething like button tabs in tableau. As shown in the screenshot below. The blue are thhe buttons, on which If I will click it will take to a dashboard.
Similarly on the Second Image, if buttons are inserted on the TOP , that will take to the particular Dashboard page.
Can we craete something like this?
