Menu moves other objects on hover.

When I hover "sites" link in the meny it moves everything to the side. How to prevent it?

#nav li {
  list-style: none;
  margin-left: 1em;
  float: left;  
}

/* Hidden menu */
#nav ul { 
  overflow: hidden
  position: absolute; */
  display: none;
  padding:0;

}

#nav ul li {    
  float: none;
  margin: 0;
  padding: 0;
}

#nav a {
  padding: 5px;
  display: block;
  text-decoration: none;
}

#nav a:hover {
    background: #f8f8f8;
}

#nav li:hover > ul {
    display: block; /* show dropdown on hover */
}

    <ul id="nav">
      <li><a href="#">Home</a></li>
          <li><a href="#">Sites
            </a>
            <ul>
              <li><a href="http://webdesignerwall.com">Web Designer Wall</a></li>
              <li><a href="http://themify.me">Themify</a></li>

              <li><a href="http://bestwebgallery.com">Best Web Gallery</a></li>
            </ul>
          </li>
          <li><a href="#">About</a></li>
          <li><a href="#">Contact</a></li>
          <li><a href="#">Another Button</a></li>
    </ul>

Don't know if this will help but I have edited the above CSS a bit. Let me know :)

#nav li {
  list-style: none;
  margin-left: 1em;
  float: left;  
}

/* Hidden menu */
#nav ul { 
  overflow: hidden;
  position: absolute; */
  display: none;
  padding:0;

}

#nav ul li {    
  float: none;
  margin: 0;
  padding: 0;
}

#nav li > ul {
  display: none;
}

#nav a {
  padding: 5px;
  display: block;
  text-decoration: none;
}

#nav a:hover {
    background: #f8f8f8;
}

#nav li:hover > ul {
    display: block; /* show dropdown on hover */
}

Oh! and try this and see if it makes a difference

* {
box-sizing: border-box;
}

It will stop minus any padding to the total width of the element, rather than adding it to the total width. That piece of code should be at the top of every project :)

I've put your code in a CodePen and it looks to be behaving as required:

(Added a semi-colon, and removed the comment closing tag in #nav ul )
