I am using Zend Framework 2 Forms using array notion for a select (drop down box). Code snippet from MenuForm.php is below:
$options_for_select = $menuTable->GetParents();
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'name' => 'parent',
'attributes' => array(
'options' => $options_for_select,
),
'options' => array(
'label' => 'Select parent item',
),
)
);
When this drop down changes I would like to populate another drop down list on the form with a list of options that are related to the item selected in the parent drop down list.
How can I achieve this?
Thank you.
