Custom side-nav for a specific section

Hello! I am working on a section within a page that will require a "side-nav" type of feature. The content on the right side of the section will change based on the side-nav link that's selected (design screenshotted below). 

How should this be set up? I'm assuming it will require a bit of custom work, but I'm not really sure where to start. 

@chymer Hi! To implement the feature, you need to create four sections: the first one for the side navigation, and the next three sections associated with side navigation items. After that, you'll need quite a bit of custom code to adjust the layout based on the screenshot you shared and ensure that each of the last three sections is visible only when a corresponding navigation item from the sidebar is selected.

Thanks @Lesum

I actually found this plugin that made this much easier to implement: https://www.will-myers.com/products/p/tabs-plugin-for-squarespace
