What can I do to my JavaScript code so that "treeview-menu menu-open" is hidden when I click on any part of the body?

One way to do this is by adding an event listener to the body that listens for a click event, and then removes the "menu-open" class from any elements with the "treeview-menu" class.

Here's an example of how this can be done:

document.body.addEventListener('click', function() {
  var menuOpen = document.querySelectorAll('.treeview-menu.menu-open');
  menuOpen.forEach(function(menu) {
    menu.classList.remove('menu-open');
  });
});

This code adds a click event listener to the body and uses the querySelectorAll method to find all elements that have the "treeview-menu" and "menu-open" classes. Then, it removes the "menu-open" class from each element found.

By doing this, any time the body is clicked, any open menus will be closed.
