A Laravel/Lumen Package that extends Collection to handle unlimited nested items following adjacency list model.

Installation
------------

[](#installation)

Run `composer require typicms/nestablecollection`

Usage
-----

[](#usage)

The model must have a **parent\_id** attributes :

```
protected $fillable = array(
    'parent_id',
    // …
}
```

and must use the following trait:

```
use TypiCMS\NestableTrait;
```

Now each time you get a collection of that model, it will be an instance of **TypiCMS\\NestableCollection** in place of **Illuminate\\Database\\Eloquent\\Collection**.

If you want a tree of models, simply call the nest method on a collection ordered by parent\_id asc and pass the column on which you want the nesting to occurr :

```
Model::orderBy('parent_id')->get()->nest('parent_id');
```

Of course you will probably want a position column as well. So you will have to order first by parent\_id asc and then by position asc.

Indented and flattened list
---------------------------

[](#indented-and-flattened-list)

`listsFlattened()` method generate the tree as a flattened list with id as keys and title as values, perfect for select/option, for example :

```
[
    '22' => 'Item 1 Title',
    '10' => '    Child 1 Title',
    '17' => '    Child 2 Title',
    '14' => 'Item 2 Title',
]
```

To use it, first call the `nest()` method, followed by the `listsFlattened()` method:

```
Model::orderBy('parent_id')->get()->nest('parent_id')->listsFlattened();
```

By default it will look for a `title` column. You can send a custom column name as first parameter:

```
Model::orderBy('parent_id')->get()->nest('parent_id')->listsFlattened('name');
```

Four spaces are used to indent by default, to use your own use the `setIndent()` method, followed by the `listsFlattened()` method:

```
Model::orderBy('parent_id')->get()->nest('parent_id')->setIndent('> ')->listsFlattened();
```

Results:

```
[
    '22' => 'Item 1 Title',
    '10' => '> Child 1 Title',
    '17' => '> Child 2 Title',
    '14' => 'Item 2 Title',
]
```

Nesting a subtree
-----------------

[](#nesting-a-subtree)

This package remove items that have missing ancestor, this doesn’t allow you to nest a branch of a tree. To avoid this, you can use the `noCleaning()` method:

```
Model::orderBy('parent_id')->get()->noCleaning()->nest('parent_id');
```
