Treeview menu with checkbox and multiple selects

I have some categories with subcategories and need create a treeview menu in this menu, need have checkbox to check multiple categories and subcategories, when click in a subcategory the category need be checked too.

My database structure:
category_table (all categories)
subcategory_table (all subcategories)
product_category (checked categories in product page)
product_subcategory (checked subcategories in product page)

My site is Codeigniter and I need keet the pattern.

Likewise attachment but accept suggestions.
