Add minItems to Stack field

[Adriano Faria]

Can you please add a minItems to the Stack field?

class _Stack extends FormAbstract
{
	/**
	 * @brief	Default Options
	 */
	protected $defaultOptions = array(
		'stackFieldType'	=> 'Text',
		'removeEmptyValues'	=> TRUE,
		'maxItems'		=> NULL
	);

Sometimes we need to limit  by a min entries too, not only max.

Thank you.

I'm able to make a validation:

$form->add( new \IPS\Helpers\Form\Stack( 'question_wrong', isset( $question['question_wrong']) ? json_decode( $question['question_wrong'], TRUE ) : array(), TRUE, array( 'maxItems' => $container->max_answers-1 ), function( $val ) use( $container ) {
				if( $val and is_array( $val ) AND count( $val ) < $container->min_answers-1 )
				{
					throw new \InvalidArgumentException( 'quizz_min_number_questions_required' );
				}
			}, NULL, NULL, 'question_wrong' ) );

But I'm also able to make it for max items, so for consistency sake,  minItems would save us time.

Good suggestion, I've raised it internally for further consideration
