How to Add Dynamic Row on Store Configuration in Magento 2

In this article, we’re going to show you how to add a Dynamic Row on backend configuration in Magento 2 with a two text fields.

Before we start I assume, you have already a created custom module. If you don't have it or don't know how to create it then check out our other article How To Create a Magento 2 Module.

Let's get started !!

We hope you already have a system.xml file in your module. If you don't have it then check the below steps and create it.

Step 1: Create system.xml at app/code/Vendor/MultiRowConfig/etc/adminhtml and paste the below code. You need to change code as per your requirement.

<?xml version="1.0"?> <config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd"> <system> ... <field id="test_multi_row" translate="label" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1"> <label>Multi Row</label> <frontend_model>Vendor\MultiRowConfig\Block\Adminhtml\MultiRow</frontend_model> <backend_model>Magento\Config\Model\Config\Backend\Serialized\ArraySerialized</backend_model> </field> ... </system> </config>

In the above code, you see we've used frontend model as a Vendor\MultiRowConfig\Block\Adminhtml\MultiRow block to manage the dynamic row in the store configuration. Also use magento 2 default backend_model for an array serialization.

Now, let's create a block file to add fields in a dynamic row.

Step 2: Create MultiRow.php file at app/code/Vendor/MultiRowConfig/Block/Adminhtml/ folder to create block file. And paste the below code.

<?php namespace Vendor\MultiRowConfig\Block\Adminhtml; use Magento\Config\Block\System\Config\Form\Field\FieldArray\AbstractFieldArray; class MultiRow extends AbstractFieldArray { protected function _prepareToRender() { $this->addColumn('label', ['label' => __('Label'), 'class' => 'required-entry']); $this->addColumn('value', ['label' => __('Value'), 'class' => 'required-entry']); $this->_addAfter = false; $this->_addButtonLabel = __('Add'); } }

In above code we've added 2 text fields Label and Value. You can see it on the below screenshot.

Now, open Command line in folder root of magento and run the below commands.

php bin/magento c:c

You will see Dynamic Row in a text field like the below screenshot.
