Laravel, designing EAV with attribute groups and sorting?

Question

MySQL

Tell me, did I design the database for the online store correctly? Link to
the DB diagram:
https://dbdesigner.page.link/uZzxx2DakuEeMrcN8

when opening a product card, I get the names of the attributes through their values.

The bottom line is that now I need to add "sorting attribute groups within a category" and "sorting attributes within a group" to this structure.

Tell me if the solution will be correct if I add the order fields to the table pivot?
