Create a dynamic breadcrumb navigation for the GOODS4PAWS site that includes main categories and subcategories, with the active subcategory highlighted.

Requirements:

Breadcrumb Structure:

Show the full path to the current page, including all relevant subcategories, e.g., Home > Category > Subcategory > Current Page.

Subcategory Menu:

Each category should display its relevant subcategories, which automatically load from the database or data source.

Active State:

Highlight the active subcategory in the menu to show the user’s current location on the site.

Responsive Design:

Breadcrumbs should be mobile-friendly, showing a simplified view on smaller screens.
