Why is multi-select greyed out in my dropdown filter?

If your multi-select option is greyed out in a dropdown filter, this is because other panels or components in your dashboard are using operators that are not compatible with multi-selects such as the "contains" operator.

How to fix this issue

You have two options to resolve this:

1. Update the operators across all components: Change the filter operators from "contains" to a compatible operator (like "equals") in all panels that use this dropdown filter.

2. Set up filters in the dropdown config (recommended): Instead of configuring filters on individual components, configure the filters directly in the dropdown's settings. This approach provides better consistency and avoids operator conflicts.

We generally recommend the second approach as it centralizes your filter configuration and prevents similar issues from occurring in the future.
