How To Display Submenu On Dropdown Using Positioning And Css?

June 22, 2024 Post a Comment

I have this simple navigation menu for my design. But the problem is I can't display the sub menu when hovered. Is there any way to solve this? Or does my CSS has some missing styl

Solution 1:

There are quite a few errors in your code. The most critical one is the top: 100% on the submenu container, which moves it out of the visible area.

Apart from that it's important to define the submenu header li as position: relative and the submenu ul itself by default display: none and on hover display: block. And put the submenu container into the li that serves as its header. See my code below:

navul {
  list-style-type: none;
  background: #000;
}

navli {
  display: inline-block;
  position: relative;
}

navli>a {
  padding: 15px15px;
  display: inline-block;
  text-decoration: none;
  color: white;
  text-align: center;
}

navli>a:hover {
  background: violet;
}
navulliul {
  display: none;
  position: absolute;
  top: 45px;
  left: 0px;
  width: 100px;
  overflow: visible;
  padding: 0;
}
navulli:hoverul {
  display: block;
}
navululli {
  background: green;
  display: block;
}
navululli>a:hover {
  color: red;
}

Solution 2:

navul {
            list-style-type: none;
            overflow: hidden;
            background: #000;
            position: relative;
        }

        navli {
            float: left;
        }

        navli > a {
            padding: 15px15px;
            display: inline-block;
            text-decoration: none;
            color: white;
            text-align: center;
        }

        navli > a:hover {
            background: violet;
        }

        navulul {
            background: green;
            top: 100%;
        }

        navullia + ul {
            display: none;
        }

        navullia:hover + ul {
            display: block;
        }
        
        .sub-menu:hover {
            display: block;
        }

Just try this one. You could learn from it.

<!DOCTYPE html><html><head><style>ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    background-color: #333;
}

li {
    float: left;
}

lia, .dropbtn {
    display: inline-block;
    color: white;
    text-align: center;
    padding: 14px16px;
    text-decoration: none;
}

lia:hover, .dropdown:hover.dropbtn {
    background-color: red;
}

li.dropdown {
    display: inline-block;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px8px16px0pxrgba(0,0,0,0.2);
    z-index: 1;
}

.dropdown-contenta {
    color: black;
    padding: 12px16px;
    text-decoration: none;
    display: block;
    text-align: left;
}

.dropdown-contenta:hover {background-color: #f1f1f1}

.dropdown:hover.dropdown-content {
    display: block;
}
</style></head><body><ul><li><ahref="#home">Home</a></li><li><ahref="#news">News</a></li><liclass="dropdown"><ahref="javascript:void(0)"class="dropbtn">Dropdown</a><divclass="dropdown-content"><ahref="#">Link 1</a><ahref="#">Link 2</a><ahref="#">Link 3</a></div></li></ul><h3>Dropdown Menu inside a Navigation Bar</h3><p>Hover over the "Dropdown" link to see the dropdown menu.</p></body></html>
