If you would like to have the same tabs on several, many, or all product pages, it can be time-consuming to manually add the tabs HTML code to each product description.
Instead of manually adding the code, it is possible to customize the product template to automatically include the tabs on every product page using that template.
Add a Custom Liquid section
Each Online Store 2.0-compatible theme includes a Custom Liquid section to enhance pages. Confirm your theme is compatible with OS 2.0, then complete these steps.
Open template
In your theme editor (Customize), use the page selector to open Products, then Default product.
Add section
In the left sidebar, select (+) Add section, then Custom liquid.

Add code
Open the Custom liquid section, then add the tab code to the Custom liquid field.
