How can we create user defined parameters in metabase as we can create in tableau??
Or can anyone suggest another approach though which we can create a user defined drill down....
Hi @pshrikha
That is currently not possible:

My workaround has been to create a view that replicates the data for each userID (this is for security). The dashboard is embedded and the userID hidden and passed with the embedding code. That then filters both the data and the parameter lists. Might work for you, depends what you're trying to do.
