Magento 2. How to Add Custom Product Tab? — Advanced

This tutorial provides step-by-step instructions on how to add a custom tab to the Product Details Page of your Magento 2 store.

By default, there are three navigational tabs on all product pages and they are:

  • Details shows product description.
  • More Information displays data from product attributes.
  • Reviews. Product reviews by customers.

 

We will add “Ask a Question”  form as another tab to the Product Details Page.

Add an Attribute

The first thing we have to do is create an attribute and attribute set.

1. Switch to your Magento store Dashboard.

2. Navigate to Stores section and tab Products under the Attributes section.

3. Click the Add New Attribute button.

4. Specify the Default Label for the attribute.

5. Expand the Advanced Attribute Properties tab and move to the Attribute Code option.

Enter your own attribute code in lowercase characters and without spaces.

Make sure to remember the value from Attribute Code field.

In case you leave the field black the system will create the attribute code on the basis of Default Label.

So, if you enter the Ask a Question the attribute code will be ask_a_question after you save the Attribute.

6. Remember to Save the attribute.

You can see the Attribute Code indicated in the table on the Product Attributes Management page.
