Displaying a submenu upon hovering within its designated CSS region

I'm encountering an issue with my submenu. It's supposed to appear when hovering over the parent menu li, but it also shows up when the mouse hovers over its area. Let's take a look at some images.

First screenshot below shows that it works properly: https://i.stack.imgur.com/3Xn6T.png

Second screenshot below shows the submenu appearing when hovering over a list item in the submenu:

https://i.stack.imgur.com/de3nZ.png

Now let's review the HTML code:

<nav class="header-navigation">
    <ul>
        <li><a href="">Home</a></li>
        <li>
            <a href="">Blog Styles</a>
            <ul>
                <li><a href="">Image Post</a></li>
                <li><a href="">Audio Post</a></li>
            </ul>
        </li>
        <li>
            <a href="">Level 1</a>
        </li>
    </ul>
</nav>

And here is the CSS:

nav.header-navigation ul > li > ul{
    background: #fff;
    box-shadow: 0px 2px 15px rgba(0,0,0,0.1);
    position: absolute;
    z-index: 999;
    width: auto;
    top: 21px;
    white-space: nowrap;
    padding: 15px 17px 13px;
    margin-top: 18px;
    left: 0;
    visibility: hidden;
    opacity: 0;
    transform: translateY(10px);
    -webkit-transform: translateY(10px);
    -moz-transform: translateY(10px);
    -ms-transform: translateY(10px);
    -o-transform: translateY(10px);
    transition: all .3s ease;
    -moz-transition: all .3s ease;
    -webkit-transition: all .3s ease;
    -o-transition: all .3s ease;
    -ms-transition: all .3s ease;

}
nav.header-navigation > ul > li:hover > ul{
    visibility: visible;
    opacity: 1;
    transform: rotate(0deg) translateY(0px);
    -webkit-transform: rotate(0deg) translateY(0px);
    -moz-transform: rotate(0deg) translateY(0px);
    -ms-transform: rotate(0deg) translateY(0px);
    -o-transform: rotate(0deg) translateY(0px);
}
nav.header-navigation > ul > li > ul > li:hover > ul{
    visibility: visible;
    opacity: 1;
    transform: rotate(0deg) translateY(0px);
    -webkit-transform: rotate(0deg) translateY(0px);
    -moz-transform: rotate(0deg) translateY(0px);
    -ms-transform: rotate(0deg) translateY(0px);
    -o-transform: rotate(0deg) translateY(0px);
}

Answer №1

If my understanding is correct, you are encountering difficulties when hovering outside the link labeled "Blog Styles" with the same y-coordinate but different x-coordinate. This issue arises because the current width of the "li" element covers your entire screen, allowing for hover interactions at any x-coordinate as long as the y-coordinate remains constant.

To resolve this problem, adjust the width of the "li" element to specify a smaller area for hovering. For instance -

    <ul>
    <li><a href="">Home</a></li>
    <li class = "test">
        <a href="">Blog Styles</a>
        <ul>
            <li><a href="">Image Post</a></li>
            <li><a href="">audio post</a></li>
        </ul>
    </li>
    <li>
        <a href="">Level 1</a>
    </li>
</ul>

By applying the same CSS rules and introducing the class ".test" with a specific width - 

.test {
   width: 100px;
}

The class will now have a width of 100 pixels, restricting hover actions within the designated list area only.
