This is a neat navigation menu that looks like accordion tabs and has a slider like an animation for the tabs, it will look great for the hero section of a web page. It was designed by Ettrics.
You have multiple tabs that act as the menu for a section or even as the navigation menu for a website. When you click on them each section slides into view like a typical slider. On smaller devices, the title of each tab is reduced to just the first character.
