Menu dropdown responsive com HTML e CSS

Menu dropdown responsive com HTML e CSS

Veja neste tutorial como criar um Menu dropdown responsive com html e css e jquery para dar o efeito mobile.

Nesta seção, projetaremos uma estrutura simples na tag <div>, <nav>, <ul> ,<li> , <span> e a <a> para inserirmos o link de destino. 

Essas são as tags que usaremos para criar o nosso Menu dropdown.

Vamos Adicionar o HTML

        <div class="menu">

            <nav class="main-nav">
            
              <ul>
                
                <li><a href="#" title="Home">Home</a></li>
                
                <li><a href="">Front-end</a>
                 
                    <ul>
                        
                        <li><a href="#" title="Html">Html</a></li>
                        <li><a href="#" title="Css">Css</a></li>
                        <li><a href="#" title="Jquery">Jquery</a></li>

                    </ul>

                </li>
                
                <li><a href="">Back-end</a>
                
                    <ul>

                        <li><a href="#" title="PHP">PHP</a></li>

                          </ul>
                        
                        </li>
                        
                      
                    </ul>

                </li>

                <li><a href="#" title="Blog">Blog</a></li>
                <li><a href="#" title="Fale Conosco">Fale Conosco</a></li>
              
              </ul>
            
            </nav>

            <div class="mob-btn">
              <span></span>
              <span></span>
              <span></span>
            </div>

            <div class="overlay"></div>
          
        </div><!-- menu -->

Vamos Adicionar o CSS

Vamos Adicionar o script para dar o efeito mobile

<script src="js/jquery.js"></script>
<script>
    
    //Menu
    $(".main-nav ul li:has(ul)").addClass("submenu");
    $(".main-nav ul li:has(ul)").append("<i></i>");
    $(".main-nav ul i").click(function() {
      $(this)
        .parent("li")
        .toggleClass("open");
      $(this)
        .parent("li")
        .children("ul")
        .slideToggle();
    });

    //Menu Mobile
    $(".mob-btn").click(function() {
      if (!$("html").hasClass("show-menu")) {
        $("html").addClass("show-menu");
      } else {
        $("html").removeClass("show-menu");
      }
    });

    $(".overlay").click(function() {
      if ($("html").hasClass("show-menu")) {
        $("html").removeClass("show-menu");
      }
    });

    //Aparecer addClass
    $(".first ul")
      .clone()
      .prependTo(".main-nav")
      .addClass("desk-hide");
    $(".last ul")
      .clone()
      .appendTo(".main-nav")
      .addClass("desk-hide");

</script>
