How to display structured child categories?

Question

WooCommerce

Good afternoon!
Faced the problem of displaying the titles of subcategories in the parent category.
For example, there is a parent category - Rolls, which displays all the products of the child subcategories (Hot rolls, Baked rolls, etc.) on the page.
I can't figure out how to display the subcategory headings and next to display the product from this subcategory.
The subheadings of subcategories, I can only display the type of breadcrumbs.
And you need the output on the page to be as follows:
Rolls
- Hot rolls
product product product
, etc.
- Baked rolls
product product product
, etc.
those. so that the title of the subcategory and immediately the products from this subcategory are displayed in the cycle, etc.
Now all products are displayed in the parent category. I would like to structure the output.
Tell me, please, the solution or in which direction to dig?) Thank you!

Look here There is a link to a page which is also organized. And in the comments a description of the method. Only this method will work correctly provided that you do not have pagination on the page.
