# `Cinder.PageSize`
[🔗](https://github.com/sevenseacat/cinder/blob/v0.16.0/lib/cinder/page_size.ex#L1)

Page size configuration for Cinder table components.

## Configuration

Set a global default page size in your application configuration:

    # config/config.exs
    config :cinder, default_page_size: 50

    # Or with configurable options (shows dropdown selector)
    config :cinder, default_page_size: [default: 25, options: [10, 25, 50, 100]]

Individual tables can override the global default:

```heex
<Cinder.collection page_size={100} ...>
</Cinder.collection>
```

# `get_default_page_size`

Gets the raw default page size from application configuration.

Returns the configured value or 25 if not set.

# `parse`

Parses a page size value into a standardized config map.

Accepts an integer, keyword list with `:default` and `:options` keys,
or `nil` to use the global default.

# `validate`

```elixir
@spec validate(term(), map()) :: integer()
```

Validates a requested page size against the table's configuration.

Non-configurable tables (e.g. `page_size={100}`) ignore any requested value
and always return the developer's configured size — the user has no UI to
change it, so the URL must not be able to either.

Configurable tables accept only values present in `page_size_options`; any
other value falls back to `default_page_size`.
