Hi, this is my filter config for Tedomir\Blog\Models\Post

`location:

    label: Location

    modelClass: Tedomir\Blog\Models\Post

    type: group

    nameFrom: location

    conditions: location in (select location from tedomir_blog_posts where id in (:filtered))

`

Basically what i want is filtering lists by available locations, but I can't find a solution for my problem - I want to filter out empty values and duplicates, how do i apply a scope for available values in the dropdown?

Thanks to your question I found a solution to filter with multiple categories.

// Table planetadeleste_catalog_product_categories
product_id
category_id

categories:
    label: Categories
    modelClass: PlanetaDelEste\Catalog\Models\Category
    nameFrom: name
    conditions: id in (select product_id from planetadeleste_catalog_product_categories where category_id in (:filtered))

Thanks
