Create Dynamic Mass Action In Magento2 Grid

Create Dynamic Mass Action In Magento2 Grid : if you want to create dynamic mass action in any custom grid of magento2, to achieve this you have to follow some steps .

1. Write mass action code in your ui component phtml file

 <massaction name="listing_massaction">
      <argument name="data" xsi:type="array">
          <item name="config" xsi:type="array">
              <item name="selectProvider" xsi:type="string">dynamicmassaction_massaction_listing.dynamicmassaction_massaction_listing.dynamicmassaction_massaction_columns.ids</item>
              <item name="component" xsi:type="string">Magento_Ui/js/grid/tree-massactions</item>
              <item name="indexField" xsi:type="string">entity_id</item>
          </item>
      </argument>
      <action name="change_status">
         <settings>
            <type>change_status</type>
            <label translate="true">Change Status</label>
            <actions class="Webkul\DynamicMassaction\Ui\Component\MassAction\Badge\Assignoptions"/>
        </settings>
     </action>
</massaction>

Lets take chunk of the above code for better understanding

<action name="change_status">
   <settings>
      <type>change_status</type>
          <label translate="true">Change Status</label>
             <actions class="Webkul\DynamicMassaction\Ui\Component\MassAction\Badge\Assignoptions"/>
   </settings>
</action>

Here you will see a line, where you have to set the path for manipulation of the dynamic mass action

<actions class="Webkul\DynamicMassaction\Ui\Component\MassAction\Badge\Assignoptions"/>

2. Now we need to add few more lines in the etc/di.xml file as below.

<type name="Webkul\DynamicMassaction\Ui\Component\MassAction\Badge\Assignoptions">
    <arguments>
        <argument name="data" xsi:type="array">
            <item name="urlPath" xsi:type="string">dynamicmassaction/dynamic/changestatus</item>
            <item name="paramName" xsi:type="string">entity_id</item>
            <item name="confirm" xsi:type="array">
                <item name="title" xsi:type="string" translatable="true">Change Status</item>
                <item name="message" xsi:type="string" translatable="true">Are you sure to change the active status of selected gift card(s)?</item>
            </item>
        </argument>
    </arguments>
</type>

3. in this path Webkul\DynamicMassaction\Ui\Component\MassAction\Badge\Assignoptions you need to manipulate your massaction

<?php

namespace Webkul\DynamicMassaction\Ui\Component\MassAction\Badge;

use Magento\Framework\UrlInterface;
use Zend\Stdlib\JsonSerializable;
use Webkul\DynamicMassaction\Model\ResourceModel\Badge\CollectionFactory;

/**

 */
class Assignoptions implements JsonSerializable
{
    /**
     * @var array
     */
    protected $options;

    /**

     */
    protected $collectionFactory;

    /**

    protected $data;

    /**

     */
    protected $urlBuilder;

    /**

    protected $urlPath;

    /**

     * @var string

    protected $paramName;

    /**

     *
     * @var array
     */
    protected $additionalData = [];

     * Constructor
     *
     * @param UrlInterface $urlBuilder

     */
    public function __construct(
        UrlInterface $urlBuilder,
        array $data = []
    ) {
        $this->data = $data;
        $this->urlBuilder = $urlBuilder;
    }
 
    /**
     * Get action options
     *
     * @return array
     */
    public function jsonSerialize(): mixed
    {
        if ($this->options === null) {
            // get the massaction data from the database table
            //make a array of massaction
            $options[0]['value']='no';
            $options[0]['label']='Disable';
            $options[1]['value']='yes';
            $options[1]['label']='Enable';
            $this->prepareData();
            foreach ($options as $optionCode) {
                $this->options[$optionCode['value']] = [
                    'type' => 'change_' . $optionCode['value'],
                    'label' => $optionCode['label'],
                ];
 
                if ($this->urlPath && $this->paramName) {
                    $this->options[$optionCode['value']]['url'] = $this->urlBuilder->getUrl(
                        $this->urlPath,
                        [$this->paramName => $optionCode['value']]
                    );
                }
 
                $this->options[$optionCode['value']] = array_merge_recursive(
                    $this->options[$optionCode['value']],
                    $this->additionalData
                );
            }
             
            // return the massaction data
            $this->options = array_values($this->options);
        }
        return $this->options;
    }
 
    /**
     * Prepare addition data for subactions
     *
     * @return void
     */
    protected function prepareData()
    {
          
        foreach ($this->data as $key => $value) {
            switch ($key) {
                case 'urlPath':
                    $this->urlPath = $value;
                    break;
                case 'paramName':
                    $this->paramName = $value;
                    break;
                default:
                    $this->additionalData[$key] = $value;
                    break;
            }
        }
    }
}

3. Now you will see your dynamically added mass actions are displaying on grid.

So in this way, you can add dynamic massaction in your grid.Hope this blog will help you.
