Navigation menu experiencing issues with dropdown functionality

My issue arises when attempting to display the child level menus upon hovering over the top level navigation menu.

The structure of my nested navigation menu, as seen in the browser view source, is outlined below:

<div id="topmenu-position"> 
    <nav class="sort-pages modify-pages" id="navigation" role="navigation">
        <ul aria-label="Site Pages" role="menubar">
            ...
        </ul>
    </nav>
</div>

The freemarker template responsible for generating this HTML is shown here:

<nav class="${nav_css_class}" id="navigation" role="navigation">
    <ul aria-label="<@liferay.language key="site-pages" />" role="menubar">
        ...
    </ul>
</nav>

As for the CSS styling, some rules are not being applied correctly, specifically

div#topmenu-position ul li:hover ul li a
. I have checked the Styles tab in Chrome Developer Tools but cannot pinpoint the issue. Could it be a problem within my CSS code?

This problem occurs within an environment using Alloy UI with Liferay, which generates additional dynamic CSS styles.

Answer №1

To implement this style, simply include the following CSS:

div#topmenu-position ul li:hover ul {
    display: block;
}

Alternatively, you can try:

div#topmenu-position ul li:hover ul {
    display: block !important;
}

For a working example, check out this JSFiddle.

Answer №2

Upon a recommendation, I included the following section:

div#topmenu-position ul li:hover ul {
            display: block;
}

Unfortunately, this solution did not resolve the issue for me.

Subsequently, within the css segment:

div#topmenu-position ul li{
    border-right:1px solid #0a6aa7;
    border-left:1px solid #199fd1;
    display:table-cell;
    width:0%;
    overflow:hidden;
    margin-bottom:0;
}

After removing the overflow:hidden; and performing a cleaning of the Liferay theme project followed by recompilation, the problem was resolved.

Interestingly, the same property functioned correctly in a standalone HTML/CSS demonstration akin to what was presented by @Love Trivedi in their fiddle. However, it proved ineffective within the context of the Liferay theme project.
