# Decade Collections

The `decade` Default Collection File is used to dynamically create collections based on the decades available in your library, sorted by critic rating to create a "best of <decade>"

**This file works has a Show Library [Counterpart](../show/decade.md).**

## Requirements & Recommendations

Supported Library Types: Movie

## Collections Section 100

| Collection                                           | Key                               | Description                                                                    |
|:-----------------------------------------------------|:----------------------------------|:-------------------------------------------------------------------------------|
| `Decade Collections`                                 | `separator`                       | [Separator Collection](../separators.md) to denote the Section of Collections. |
| `Best of <<Decade>>`<br>**Example:** `Best of 2020s` | `<<Year>>`<br>**Example:** `2020` | Collection of Movies released in this Decade.                                  |

## Config

The below YAML in your config.yml will create the collections:

```yaml
libraries:
  Movies:
    collection_files:
      - pmm: decade
```

## Template Variable Default Values

Template Variables can be used to manipulate the file in various ways to slightly change how it works without having to make your own local copy.

This file contains a [Separator](../separators.md) so all [Shared Separator Variables](../separators.md#shared-separator-variables) are available as well.

| Variable                      | Description & Values                                                                                                                                                                                                      |

### Example Template Variable Amendments

The below is an example config.yml extract with some Template Variables added in to change how the file works.

???+ tip

    Anywhere you see this icon:
   
    > :fontawesome-solid-circle-plus:
   
    That's a tooltip, you can press them to get more information.

```yaml
libraries:
  Movies:
    collection_files:
      - pmm: year
        template_variables:
          sep_style: purple #(1)!
          sort_by: title.asc 
          sort_by_2020: release.desc #(2)!
```

1.  Use the purple [Separator Style](../separators.md#separator-styles)
2.  Set the sort order for "Best of 2020s" to release date descending
