MaterialChoiceTreeType

MaterialChoiceTreeType renders checkbox choices using choices tree layout. Requires Javascript component to work as expected.

Type options

Option Type Default value Description
choices_tree array [] The choices array to select from
choice_label string ‘name’ The key in options array to target when getting label for checkbox
choice_value string ‘id’ The key in options array to target when getting value for checkbox
choice_children string ‘children’ The key in options array to target when getting the child for checkbox
multiple bool true Whether to enable multiple checkboxes selection or no
disabled_values array [] Array of ids to disable in choices tree

Required Javascript components

Component Description
../admin-dev/themes/new-theme/js/components/form/choice-tree.js Manages UI interactions: expanding and collapsing tree, auto-checking child checkbox, enabling and disabling inputs.

Code example

<?php
// path/to/your/CustomType.php
    
use PrestaShopBundle\Form\Admin\Type\MaterialChoiceTreeType;
use Symfony\Component\Form\AbstractType;

class CustomType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('categories', MaterialChoiceTreeType::class, [
                'choices_tree' => [
                    'id' => 1, // choice_value option refers this key
                    'name' => 'Home', //choice_label option refers this key
                    'children' => [ // choice_children refers this key
                        'id' => 2,
                        'name' => 'Example',
                        'children' => [
                            'id' => 3,
                            'name' => 'Example child',
                        ],
                    ],
                ],
            ])
        ;
    }
}

Then in Javascript you have to enable ChoiceTree component.

import ChoiceTree from 'admin-dev/themes/new-theme/js/components/form/choice-tree';

// initiate the component by providing your tree selector
new ChoiceTree('.js-tree-selector-example');

// you can enable auto checking children elements
ChoiceTree.enableAutoCheckChildren();

// you can also enable or disable all inputs
ChoiceTree.enableAllInputs(); //enable
ChoiceTree.disableAllInputs(); //disable
