I've set up a codepen that illustrates what I'm trying to do. I have a menu that uses

<details>

tags for submenu folding. I want to be able to maintain the state of each details tag (open/closed) when a user clicks a link, while also swapping in each individual menu item that has changed from active to non-active and vice-versa. https://codepen.io/36864-the-styleful/pen/jOxGwVr?editors=1001
