Time:01-01

I have use this default menu in my blogger template but I have noticed the library used on it affacting the Web speed. So please anyone help me to make this menu without jquery library. Thank you.

<script rel='preload' src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js' type='text/javascript'></script>
<div class='main-nav-main'>
  <div class='mobile-menu' />
  <div class='ct-wrapper'>
    <span class='slide-menu-toggle'>Menu</span>
    <!-- Main menu -->
    <ul class='sf-menu'>
      <li><a href='/'>Home</a></li>
      <li><a href='/p/sample-page_12.html'>sample page</a></li>
      <li><a href='#'>drop down</a>
    </ul>
  </div>
</div>

<script type='text/javascript'>
  //<![CDATA[
  $(document).ready(function() {
    $('ul.sf-menu').clone().appendTo('.mobile-menu');
    $('.slide-menu-toggle').on('click', function() {
      $('body').toggleClass('nav-active');
    });

  });
  //]]>
</script>

Here's a remake in pure JavaScript.
Basically what it uses is:

const EL = (sel, el) => (el || document).querySelector(sel);

const EL_body = EL("body");
const EL_menu_sf = EL(".sf-menu");
const EL_menu_sf_cln = EL_menu_sf.cloneNode(true);
const EL_menu_mobile = EL(".mobile-menu");
const EL_menu_toggle = EL(".slide-menu-toggle");

EL_menu_mobile.append(EL_menu_sf_cln);

EL_menu_toggle.addEventListener("click", () => {
  EL_body.classList.toggle("nav-active");
});
.mobile-menu                 { display: none; }
body.nav-active .mobile-menu { display: block; }
<div class='main-nav-main'>
  <div class='mobile-menu'></div>
  <div class='ct-wrapper'>
    <span class='slide-menu-toggle'>Menu (click me)</span>
    <!-- Main menu -->
    <ul class='sf-menu'>
      <li><a href='/'>Home</a></li>
      <li><a href='/p/sample-page_12.html'>sample page</a></li>
      <li><a href='#'>drop down</a>
    </ul>
  </div>
</div>

And just to spice your imagination, here's one without JS at all:

#menu {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  pointer-events: none;
  visibility: hidden;
  opacity: 0;
  background: #ddd;
  color: #fff;
  display: flex;
  flex-direction: column;
  transition: 0.4s;
}

#menu nav {
  margin: auto;
  display: flex;
  gap: 1em;
  flex-direction: column;
}

.menu-icon {
  position: fixed;
  top: 1em;
  right: 2em;
  font-size: 2em;
  cursor: pointer;
}

#menu-toggle:checked~#menu {
  visibility: visible;
  opacity: 1;
  pointer-events: auto;
}
<input id="menu-toggle" type="checkbox" hidden />

<label  for="menu-toggle" aria-label="Toggle menu">☰</label>

<div id="menu">

  <label  for="menu-toggle" aria-label="Toggle menu">✖</label>

  <nav>
    <a href="#!">HOME</a>
    <a href="#!">ABOUT</a>
    <a href="#!">PRODUCTS</a>
    <a href="#!">CONTACT</a>
  </nav>

</div>
