How to Add a Drop Down in Magento 2 Admin Form

In this code snippet, we will see how to add a dropdown with custom options in Magento 2 Admin Form. We assume that you have already created a Magento 2 admin module.

Add a Drop Down in Magento 2 Admin Form

In your form file codextblog_demo_form.xml inside app/code/Codextblog/Demo/view/adminhtml/ui_component add below code.

<form xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
	<fieldset name="general">
		<field name="category" formElement="select" sortOrder="20">
            <argument name="data" xsi:type="array">
                <item name="options" xsi:type="object">Codextblog\Demo\Model\Source\Category</item>
                <item name="config" xsi:type="array">
                    <item name="source" xsi:type="string">Demo</item>
                <label translate="true">Blog Category</label>
                    <rule name="required-entry" xsi:type="boolean">true</rule>

To render options, we have specified PHP class in line no 5. Now add a Category.php file under Codextblog/Demo/Model/Source directory. Add below code in that file.

namespace Codextblog\Demo\Model\Source;

use Magento\Catalog\Model\ResourceModel\Category\CollectionFactory;
use Magento\Framework\Data\OptionSourceInterface;

class Category implements OptionSourceInterface
     * @var CollectionFactory
    protected $collectionFactory;

    public function __construct(
        CollectionFactory $collectionFactory
    ) {
        $this->collectionFactory = $collectionFactory;

    public function toOptionArray()
        $options[] = ['label' => '-- Please Select --', 'value' => ''];
        $collection = $this->collectionFactory->create()
            ->addAttributeToFilter('is_active', '1');

        foreach ($collection as $category) {
            $options[] = [
                'label' => $category->getName(),
                'value' => $category->getId(),

        return $options;

If everything works well, then you will see a dropdown with categories name as an option. Cheers!!
