Hi Metabase team,
I tried adding a categorical filter to a dashboard, but I ran into a problem.
When connecting the query directly to the dashboard and adding the filter, I can only select a single option instead of multiple choices.
How can I enable multi-select?
Hi,
To enable multi-select for a categorical filter in Metabase, you need to use a Field Filter instead of a standard variable filter in your SQL query.
Hi everyone, I’m having trouble setting up a multi-select filter for a text field. It seems like I can’t choose a categorical filter, and it’s not working. Could it be because of my Metabase version? Best, 
See the post above yours for your answer. Your question must be set up to accept multi-select filters.
If you need more help, tell us more about the question you’re having trouble attaching the filter to.
