View

<div class="control-group">
	<?= Form::label('Items', 'item_id[]', array('class'=>'control-label')); ?>

	<div class="controls">

<?php
	foreach ( Model_Item::find('all') as $item)
	{
		$checked = in_array($item->id, array_merge(
			(array) Input::post('item_id', []),
			isset($parent) ? array_keys($parent->items) : []
		));
		echo Form::label(
			Form::checkbox(
				'item_id[]',
				$item->id,
				$checked,
				['id' => 'form_item_id_' . $item->id]
			) . $item->name,
			'item_id_' . $item->id,
			['class' => 'checkbox']
		);
	}
?>

	</div>
</div>

Controller

<?php

class Controller_Parent extends Controller_Template
{

	/* ... 中略 ... */

	protected function apply_item_ids($parent)
	{
		$item_ids = (array) Input::post('item_id', []);

		foreach ( $parent->items as $item )
		{
			unset($parent->items[$item->id]);
		}

		foreach ( $item_ids as $item_id )
		{
			$parent->items[] = Model_Item::find($item_id);
		}
	}
}

改行入れたけど読みにくい罠。

あまり数の多いものには使えない。
