I have made a "master" dashboard linked to "slave" dashobard with a filter when clicking on an item of the "master" dashboard
This works fine when connected, but not when using the "master" dashboard from its public link.
Is this by design, or am I missing something when defining the link from the master to the slave dashboard.
Most of our user access the dashboard using a public link so that auth and rights management is not required.
Hey, that is by design. The data at a public link is "secure" and does not link to other things inside Metabase. But you can link them to OTHER public links
Try this:
Create a public link for the slave dashboard.
In the master dashboard, set up the click behaviour to go to the slave public link.
At the end of the slave public link, add a query parameter for the filter.
