# `PhoenixKit.Config.AdminDashboardCategories`
[🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v1.7.165/lib/phoenix_kit/config/admin_dashboard_categories.ex#L1)

Admin dashboard categories configuration and validation for PhoenixKit.

This module provides a comprehensive system for configuring custom admin dashboard
categories with subsections, including validation, type safety, and fallback to
built-in categories.

## Category Structure

Each category should have the following structure:

    %{
      title: "Category Title",
      icon: "hero-icon-name",          # Optional Heroicon name
      subsections: [
        %{
          title: "Subsection Title",
          url: "/admin/some-path",
          icon: "hero-icon-name",          # Optional Heroicon name
          description: "Brief description" # Optional
        }
      ]
    }

## Field Validation

- **title**: Required string, max 100 characters
- **icon**: Optional string, validated to be a reasonable Heroicon name
- **subsections**: Required list, can be empty
- **subsection.title**: Required string, max 100 characters
- **subsection.url**: Required string, must start with "/"
- **subsection.icon**: Optional Heroicon name validation
- **subsection.description**: Optional string, max 200 characters

## Usage

    # Get all configured categories with validation
    categories = PhoenixKit.Config.AdminDashboardCategories.get_categories()

    # Returns validated list like:
    [
      %{
        title: "User Management",
        icon: "hero-users",
        subsections: [
          %{
            title: "All Users",
            url: "/admin/users",
            icon: "hero-user-group",
            description: "Manage user accounts"
          }
        ]
      }
    ]

# `get_categories`

```elixir
@spec get_categories() :: list()
```

Gets admin dashboard categories with comprehensive validation and defaults.

This function provides a fully validated list of admin dashboard categories
with proper structure validation and fallback to built-in categories.

## Examples

    iex> PhoenixKit.Config.AdminDashboardCategories.get_categories()
    [
      %{
        title: "User Management",
        icon: "hero-users",
        subsections: [
          %{
            title: "Users",
            url: "/admin/users",
            icon: "hero-user-group",
            description: "Manage user accounts"
          }
        ]
      }
    ]

# `validate_categories`

```elixir
@spec validate_categories(list()) :: {:ok, list()} | {:error, String.t()}
```

Validates admin dashboard categories structure and content.

This function can be used to validate custom categories before setting them
in the configuration.

## Examples

    iex> categories = [
    ...>   %{
    ...>     title: "My Category",
    ...>     subsections: [
    ...>       %{
    ...>         title: "My Subsection",
    ...>         url: "/admin/my-path"
    ...>       }
    ...>     ]
    ...>   }
    ...> ]
    iex> PhoenixKit.Config.AdminDashboardCategories.validate_categories(categories)
    {:ok, validated_categories}
