Hello,
01. To enable editing the product description with Elementor, you need to add the “Product Content” widget products tabs widget to your single product layout.
Simply go to Layouts > Edit Single Product Layout, and insert the Product Content widget. This will display the product description and allow you to edit it using Elementor.
02. For the products tabs, if you want to add more global tabs (that apply to all products), you can do that by navigating to:
Theme Settings > Single Product > Tabs — under Additional Tabs, you can add more custom tabs.
Additionally, Woodmart theme provides the option to create a custom tab for every product from Products > Edit Product > On the edit product page, check the Product Settings > Tabs tab and create a custom tab for each product separately and add the content: https://ibb.co/z53zhnm
