Localization of filter names

is there a way to localize the custom filter names?

We’re currently on 6.10

Hi, do you mean the captions in the filter entities dropdown list? If so, then you need to create a filter entity with the code field filled. Then in the main message pack of the application for each language you’ll have to specify a message where the key equals the filter code. It is briefly mentioned here.

The code property cannot be edited in filter UI, so you’ll have to edit it using the Administration - Entity Inspector screen or create a filter entity by the database script.
