// CGridView

/**

	Category('id','name'); // (pk)id

	Cats('cid','pid') // (pk,fk)cid, (pk)pid 

	Category [ 1 -> n ] Cats

        ///////////////////////////////////////////////////////////////////////////

	'filter'=>CHtml::listData($model->with('cats')->findAll(),'id','name'), // work for 'id' and 'name'

	'filter'=>CHtml::listData($model->with('cats')->findAll(),'cid','name'), // work for 'name', but dont work for 'cid'
