I want to add new tab in product edit page using controller_action_layout_render_before_adminhtml_catalog_product_edit event. Can anyone help.

1 Answer 1


In 2.1+ product edit page is built using UI Components and PHP modifiers. Not sure you can modify it using mentioned event. Even if you could it's incorrect.

Hope you are familiar with UI Components. If not, these pages can help you to start: UI Components Overview, UI Components Modifiers.

Product Edit Page base configuration file


defines root modifier


Looking into you can find that it is just iterates through number of more specific modifiers. Complete list you can find in


under node

<virtualType name="Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\Pool" type="Magento\Ui\DataProvider\Modifier\Pool">


Take a look into modifier for websites

<item name="websites" xsi:type="array">
    <item name="class" xsi:type="string">Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\Websites</item>
    <item name="sortOrder" xsi:type="number">30</item>

it is most relevant to your case. It defines new collapsible section(tab) Websites In your case you need create new modifier and configure it.

Hope this will help you to understand product edit form in Magento 2 (2.1+) a bit
