Laravel - how can make dynamic content with layout?

I'm wanting to create a website with laravel framwork. I had made layout but now, have some zone i don't know how to set content for it. Ex: 2 zone of me are left-menu and cart (please view picture). My left-menu will get content from table: categories and cart will get content from package cart [Cart::content()]. It's on layout and of course, all page will have it. But i don't know how to give content of categories and cart() for it. Please help me
