Navigation
Peak includes basic unstyled responsive navigation with two levels. Open resources/views/navigation/_main.antlers.html to make changes. There's a desktop version that only shows on md screens and up as well as a mobile version that shows on smaller screens. AlpineJS takes care of the interactivity. The state of the mobile navigation toggle is defined on the <body> tag in resources/views/layout.antlers.html.
Peak also includes an installable breadcrumbs preset.
