Dynamic Filter Linking Issue in Metabase Dashboard

Question

We are facing an issue with dynamically updating filters on our Metabase dashboard.

Our Setup:

• We created filters based on questions to restrict users from viewing data from other states or districts.
• Filters include "District", "Block", "Cluster", and "Program", expecting them to work dynamically together.

Queries Used:

-- District filter query
SELECT DISTINCT(district) FROM projects WHERE state = 'Karnataka';

-- Block filter query
SELECT DISTINCT(block) FROM projects WHERE state = 'Karnataka';

-- Big number query (linked to filters)
SELECT DISTINCT(project_id) 
FROM projects 
WHERE 1 = 1 AND state = 'Karnataka' 
[[AND {{district_param}}]] 
[[AND {{block_param}}]];

Steps Followed to Set Filters:

1. Click "Add filter"
2. Select "Text" or "Category"
3. Map the filter to the big number query
4. In the filter settings, select "Dropdown box"
5. Link the District filter to the distict_filter_sql_query question
6. Select District as the column to supply values
7. Save the filter
8. Similarly, create a filter for Block

The Problem:

• When trying to link these filters, the option does not appear.
• We receive the message:
  "Limit this filter's choices: If the filter has values that are from another question or model, or a custom list, then this filter can't be limited by another dashboard filter."
• This means selecting a District does not dynamically update the Block, Cluster, and Program filters.
• This limitation makes it difficult for users to drill down or filter data correctly.

Question:

Is there a way to achieve dynamic linking between filters in Metabase?enter image description here

Answer 1

You should be able to achieve this using linked filters in Metabase. Without the full context, I’d recommend double-checking that your data has the necessary relationships (e.g., between 'District,' 'Block,' etc.).

Here’s the documentation, which might help: https://www.metabase.com/learn/metabase-basics/querying-and-dashboards/dashboards/linking-filters.
