How to add second level to a submenu in a dropdown navigation css in Blogger

问题

I am really struggling with my template. Here is my current css for the navigation menu. I have tried several things but nothing gives me a second submenu that will pop out to the right of the dropdown im already on. Can anyone help me insert code to allow for a second pop out? Thanks!!!

回答1:

Okay, if you edit the HTML & the CSS, here is how you could do it:

HTML

One of the HTML Dropdown menus look like this:

<li><a class='ai' href='#'>Dropmenu</a>
  <ul class='menus'>
    <li><a href='#'>Dropmenu 1</a></li>
    <li><a href='#'>Dropmenu 2</a></li>
    <li><a href='#'>Dropmenu 3</a></li>
    <li><a href='#'>Dropmenu 4</a></li>
    <li><a href='#'>Dropmenu 5</a></li>
  </ul>
</li>

Add this code after the Dropmenu </a> tag:

  <ul class='menus'>
    <li><a href='#'>Dropmenu 1</a></li>
    <li><a href='#'>Dropmenu 2</a></li>
    <li><a href='#'>Dropmenu 3</a></li>
    <li><a href='#'>Dropmenu 4</a></li>
    <li><a href='#'>Dropmenu 5</a></li>
  </ul>

So it to look like this:

<li><a class='ai' href='#'>Dropmenu</a>
  <ul class='menus'>
    <li><a href='#'>Dropmenu 1</a>
      <ul class='menus'>
        <li><a href='#'>Dropmenu 1</a></li>
        <li><a href='#'>Dropmenu 2</a></li>
        <li><a href='#'>Dropmenu 3</a></li>
        <li><a href='#'>Dropmenu 4</a></li>
        <li><a href='#'>Dropmenu 5</a></li>
      </ul>
    </li>
    <li><a href='#'>Dropmenu 2</a></li>
    <li><a href='#'>Dropmenu 3</a></li>
    <li><a href='#'>Dropmenu 4</a></li>
    <li><a href='#'>Dropmenu 5</a></li>
  </ul>
</li>

CSS

Then, add this CSS:

#menu .menus li > ul.menus {
  transform: translateX(100%) scale(1.0);
  top: 0;
}

#menu ul.menus {
  overflow: visible !important;
}

Final Result

It should look like this when you're done:

/* CSS Main Menu */

#menu .menus li > ul.menus {
   transform: translateX(100%) scale(1.0);
   top: 0;
}

#menu ul.menus {

  </div>
</div>
<div class='clear' />

Note: instead of:

#menu ul.menus {
  overflow: visible !important;
}

You could just remove overflow: hidden on #menu ul.menus.
