I have created a module which allows to add items dynamically from admin panel configuration. I have created form using ui component and want to add 3 fields dynamically on click of "Add More" button. I have no idea how to add dynamic fields using ui component.


Configure the container with XML

Just create a NameSpace/ModuleName/view/adminhtml/ui_component/product_form.xml file with this content:

<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">  
<fieldset name="my_fieldset" class="My\Module\Ui\Component\Form\Fieldset">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="label" xsi:type="string" translate="true">More Product Links</item>
            <item name="sortOrder" xsi:type="number">1000</item>

Dynamically create fields with PHP

This is where we will write our custom logic to inject fields into this fieldset.

So here is the NameSpace\ModuleName\Ui\Component\Form\Fieldset PHP class which.

 namespace My\Module\Ui\Component\Form;

 use Magento\Framework\View\Element\UiComponent\ContextInterface;  
 use Magento\Framework\View\Element\UiComponentInterface;  
 use Magento\Ui\Component\Form\FieldFactory;  
 use Magento\Ui\Component\Form\Fieldset as BaseFieldset;

 class Fieldset extends BaseFieldset  
 * @var FieldFactory
private $fieldFactory;

public function __construct(
    ContextInterface $context,
    array $components = [],
    array $data = [],
    FieldFactory $fieldFactory)
    parent::__construct($context, $components, $data);
    $this->fieldFactory = $fieldFactory;

 * Get components
 * @return UiComponentInterface[]
public function getChildComponents()
    $fields = [
            'label' => __('Field Label From Code'),
            'value' => __('Field Value From Code'),
            'formElement' => 'input',
            'label' => __('Another Field Label From Code'),
            'value' => __('Another Field Value From Code'),
            'formElement' => 'input',
            'label' => __('Yet Another Field Label From Code'),
            'value' => __('Yet Another Field Value From Code'),
            'formElement' => 'input',

    foreach ($fields as $k => $fieldConfig) {
        $fieldInstance = $this->fieldFactory->create();
        $name = 'my_dynamic_field_' . $k;

                'config' => $fieldConfig,
                'name' => $name

        $this->addComponent($name, $fieldInstance);

    return parent::getChildComponents();

NOTE : In above logic i added simple field. so you need to add logic for add more field using Jquery or Javascript or any other logic. i have give a siple logic how to add dynamic UI component field.

  • @ChiragPatel How would you save the data? – Anshu Mishra Oct 29 '18 at 9:34
  • @ChiragPatel can you suggest an approach to use a plugin instead of preference? – Radu Apr 10 at 9:26
