# Trek::Sectionable

Organizes a record's content into ordered, typed sections (hero, features, testimonials…).

## What it adds

When the app has a `Section` model:

* `has_many :sections, -> { ordered }, as: :sectionable, dependent: :destroy`
* `sections_instances` — the unwrapped section objects, in order

## Requirements

Trek doesn't generate the `Section` model: the app provides it, with a polymorphic `belongs_to :sectionable`, an `ordered` scope, and a `section` method returning the section's own object. Without a `Section` model, the concern adds nothing.

## Usage

```ruby
class Page < ApplicationRecord
  include Trek::Sectionable
end

page.sections_instances.each do |section|
  render section_component_for(section)
end
```

Sections are opt-in per page via the `sectioned` boolean column.
