How do I add a dropdown menu in a navbar that doesn't move the rest of the content-CodePudding

I am trying to add a dropdown menu to my navbar but if I specify position:absolute in CSS, it detaches itself from the navbar and if i leave it as position:relative, it moves the rest of the content on the page. How do I avoid this?

CodePudding user response：

you should put dropdown links inside a div


<li>
       <ul  style="position:relative">View Standings
           <div >
            <li >
              <a  href="one.html">one</a>
            </li>
             <li >
              <a  href="two.html">two</a>
            </li>
            <li >
              <a  href="etc.html">etc</a>
            </li>
          </ul>
</li>

Now you have to style the new division you created with css for example :

.inside{
        height:max-content;
        position:absolute;
        width:100%;
 }
