Theming
On large+ screen, the menu can either be displayed as “collapsed” or “expanded”. Default being “expanded”.
A particular mode can be defined by setting a corresponding attribute menu on the root html element.
<!doctype html>
<html lang="en" menu="expanded"></html>Usage
To init the menu as fast as possible, and therefore to avoid FOUC, we advise to add the following code snippet in your HTML pages.
<!-- Init menu as fast as possible as well -->
<script>
try {
const currentMenu = !localStorage.nnsMenu
? undefined
: JSON.parse(localStorage.nnsMenu);
document.documentElement.setAttribute(
"menu",
currentMenu ?? "expanded",
);
} catch (error) {
console.error("Error initializing menu", error);
}
</script>
