    Comment on it


    Hello reader's in this blog we are making a css3 dropdown menu with custom html. We dont use <select> element for creating it. I have used list <li> element for making the dropdown of the menu.

     

    HTML:-

    In the html file i have created a nested element of list. One is the parent element <li> and other is the child <li> of that parent element. By making a nested element we got the structure of the menu. For the headings i have used <h2> element if you like you can use any other element for making heading.

     

    <ul class="hList">
      <li>
        <a href="#click" class="menu">
          <h2 class="menu-title">animals</h2>
          <ul class="menu-dropdown">
            <li>cat</li>
            <li>dog</li>
            <li>horse</li>
            <li>cow</li>
            <li>pig</li>
          </ul>
        </a>
      </li>
      <li>
        <a href="#click" class="menu">
          <h2 class="menu-title menu-title_2nd">names</h2>
          <ul class="menu-dropdown">
            <li>Kevin</li>
            <li>Jim</li>
            <li>Andy</li>
          </ul>
        </a>
      </li>
      <li>
        <a href="#click" class="menu">
          <h2 class="menu-title menu-title_3rd">things</h2>
          <ul class="menu-dropdown">
            <li>bench</li>
            <li>pizza</li>
            <li>Honda CB125</li>
            <li>space</li>
            <li>black matter</li>
            <li>apple</li>
            <li>philodendron</li>
            <li>liver</li>
            <li>brass</li>
          </ul>
        </a>
      </li>
      <li>
        <a href="#click" class="menu">
          <h2 class="menu-title menu-title_4th">Movies</h2>
          <ul class="menu-dropdown">
            <li>Godzilla</li>
            <li>Man on Wire</li>
            <li>Spirited Away</li>
            <li>Interstellar</li>
          </ul>
        </a>
      </li>
    </ul>  


    CSS:-
    Inside the css first i have imported the font from google API for the text. After that i have created the style for the other elements. By default all the child element <li> is hidden and the heading is visible only. When we hover on the heading the list will appear with a dropping animation. For the dropping animation  i have used the transition property If you need you can use CSS3 animation for making the same effect of dropping menu.
