Hello Archers, most of the time it is often requires grabbing user attention on some particular section or content. For these types of requirements, a slide-out panel, modal view are efficient. Today, I came across a task where I need to open a sliding modal popup in Magento 2 on custom button. Although I already used Magento 2 default popup on the frontend but not on the backend. So, while completing my task, I created a short and efficient guide to add a sliding popup in Magento 2 with some custom content. You can also use this popup to post your request using ajax.

Problem: I am trying to add a custom button on Product edit page and on that button click I will open a popup with some field/content in it.

Note- I assume you already created a Custom module. Learn how to create a custom module in Magento 2. In my case, here is my directory structure.

Adding a custom button in magento 2 admin

As I mentioned earlier, I am adding a custom button in the Magento Product edit page to open a slide-out modal. For this purpose, I need to make some changes in product-form.xml file,

Add the following code at

<?xml version="1.0" encoding="UTF-8"?>

<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
            <button name="openModel" class="WebArchers\DirectUpload \Block\Adminhtml\Category\Edit\AddModelButton"/>
    <modal name="test_model">
                <option name="buttons" xsi:type="array">
                    <item name="0" xsi:type="array">
                        <item name="text" xsi:type="string">Done</item>
                        <item name="class" xsi:type="string">action-primary</item>
                        <item name="actions" xsi:type="array">
                            <item name="0" xsi:type="array">
                                <item name="targetName" xsi:type="string">${ $.name }</item>
                                <item name="actionName" xsi:type="string">actionDone</item>
                <option name="title" xsi:type="string">CUSTOM MODEL</option>
        <fieldset name="general" sortOrder="10">
            <field name="test1" sortOrder="10" formElement="input">
                    <label translate="true">Test 1</label>
                        <rule name="required-entry" xsi:type="boolean">true</rule>
            <field name="test2" sortOrder="20" formElement="textarea">
                    <label translate="true">Test 2</label>

As you can see, in the above code we have two main tags- settings and modal tag. While declaring the button, we defined a class to it. This class will be used to make that button functional. Let’s do that:

Add the below code at this location


namespace WebArchers\DirectUpload\Block\Adminhtml\Product\Edit;

use Magento\Framework\View\Element\UiComponent\Control\ButtonProviderInterface;

class AddModelButton implements ButtonProviderInterface
    public function getButtonData()
        return [
            'label' => __('custom button'),
            'class' => 'action-secondary',
            'data_attribute' => [
                'mage-init' => [
                    'Magento_Ui/js/form/button-adapter' => [
                        'actions' => [
                                'targetName' => 'product_form.product_form.test_model',
                                'actionName' => 'toggleModal'
            'on_click' => '',
            'sort_order' => 10

That’s it.

Run these command after:php bin/magento s:up
php bin/magento s:d:c
php bin/magento c:c

That’s all you need to do to make a sliding popup in Magento 2 admin section.

Let me know if you have any question or doubts. I am happy to help you.

If you able to add a button by this code, leave a comment says- “Completed” to appreciate your efforts and yourself.
