Vendor/Module/view/adminhtml/ui_component/category_form.xml

<?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">
<fieldset name="content">

    <field name="cat_short_description">

        </field>


</fieldset>
</form>

the code is okay but I don't have that Use Default Value checkbox when changing the Store View, what is wrong or how I can add Use Default Value checkbox?

Answer 1

I think you forgot to add the "SCOPE_STORE" while creating the custom category attribute.

You must need to add the

\Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE

For the global variable

Check the below code.

$eavSetup->addAttribute(
    \Magento\Catalog\Model\Category::ENTITY,
    'cat_short_description',
    [
        'type' => 'varchar',
        'label' => 'Category Short Description',
        'input' => 'textarea',
        'sort_order' => 100,
        'source' => '',
        'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
        'visible' => true,
        'required' => false,
        'user_defined' => false,
        'default' => null,
        'group' => 'General Information',
        'backend' => ''
    ]
);

Or you can change directly in the database by the below way (Not Tested).

Find your attribute code in "eav_attribute" and search it's attribute_id in "catalog_eav_attribute" and change the is_globle to 0 (Zero), Then reindex and check.

Hope this will help you.

Answer 2

Try to extend Magento\Catalog\Model\Category\DataProvider.

Example :

<?php

namespace Your\Namespace;

use Magento\Catalog\Model\Category\DataProvider as CategoryDataProvider;

class DataProvider extends CategoryDataProvider
{

    /**
     * Display "Use Default Value" checkbox
     *
     * @return array
     */
    protected function getFieldsMap()
    {
        $parentFieldMap = parent::getFieldsMap();
        array_push($parentFieldMap['display_settings'], 'your_attribute');

        return $parentFieldMap;
    }
}
