better handling of classic menu and neomenu

[kaguy4]

both menu types being generated into the page by a file or simply be defined in globalconfig.php file

neomenu having a class that makes it have "display: hidden", then JS toggles the class between them when u check/uncheck the setting. So an improved version of this (copying from Heyuri's source), CTRL+F for "hide":

<div class="boardlist">
		<small class="toplinks"><style>
.neomenu>li {
  float:left;
}
.neomenu li {
  width:13em;
}
.neomenu * {
  z-index:100;
}
.neomenu .menutitle {
  width:auto;
  padding-right:3em;
}
.neomenu .menutitle a:hover {
  background-color:transparent;
}
.boardNav,
.boardlist,
#boardmenu li a {
  color:inherit;
}
.neomenu li a:visited,
.neomenu li a {
  display:block;
  color:inherit;
  text-decoration:none;
}
.neomenu li a:hover {
  background-color:rgba(0,0,0,0.1);
}
.neomenu .reply {
  padding:0;
  margin:0;
}
.neomenu .menulist {
  position:absolute;
  list-style:none;
  display:none;
  border-style:solid;
  border-width:1px;
}
.neomenu>li:hover .menulist {
  display:initial;
}
.neomenu {
  list-style:none;
  margin:0;
  padding:0;
  font-size:10pt;
}
.logo {
  clear:both;
}
.boardNav.reply {
  padding:0!important;
}
</style>

  <style>
    .hide {
      display: none;
    }
  </style>

<script>
window.onload = function() {
  // Get references to both menus
  var classicMenu = document.querySelector('.classicmenu');
  var neoMenu = document.querySelector('.neomenu');

  // Check if 'neomenu' is set to 'true' in localStorage
  if (localStorage.getItem("neomenu") === "true") {
    // Show neomenu and hide classicmenu
    neoMenu.classList.remove('hide');
    classicMenu.classList.add('hide');
  } else {
    // Show classicmenu and hide neomenu (default behavior)
    neoMenu.classList.add('hide');
    classicMenu.classList.remove('hide');
  }
}
</script>
