The transition effect does not seem to be functioning correctly when adding a class

It seems like a common issue, but none of the solutions I've come across so far have helped. Everything appears to be standard and simple code, yet I can't seem to get it to work properly. I'm trying to create a dropdown menu where a hidden ul element appears slowly when hovered over.

Here is the HTML code:

<div class="main-nav">
  <ul>
    <li>
      <a href="wtvr">Title</a>
      <ul class="dropedmainnav t50 ">
        <li class="subnavli" style="position:relative;">
          <div class="superimage" style="position:absolute;  right:-100%;">
            <img src="" alt="{{link.handle}}">
          </div>
        </li>
        <li class="t50 subnavli">
          <a href="wtvr">Subnav link</a>
        </li>
        <div class="subnavsides"></div>
      </ul>
    </li>        
  </ul>
</div>   

And here is the JavaScript code:

$(".main-nav ul li").each(function(){
    $(this).mouseover(function(){$(this).find("ul").addClass("dropedunderul");});
    $(this).mouseleave(function(){$(this).find("ul").removeClass("dropedunderul"); });
    $(this).find("ul").mouseover(function(){$(this).addClass("dropedunderul");});
    $(this).find("ul").mouseleave(function(){$(this).removeClass("dropedunderul");});

And the CSS code:

.t50 {-webkit-transition: all 0.5s; -moz-transition: all 0.5s; -ms-transition: all 0.5s; -o-transition: all 0.5s; transition: all 0.5s;}
.dropedmainnav {display:none; padding:15px 0 10px 0; overflow:hidden;width:500px; }
.dropedunderul {display:table !important; min-height:150px; border-top:2px solid transparent; z-index:2; }
.main-nav ul li {position:relative;}
.main-nav ul li ul {position:absolute;background-color:rgba(255,255,255,0); overflow:visible;}
.main-nav ul li ul li {float:none !important; text-align:left !important;}

I believe these are all the relevant styles. I have also attempted to add transitions specifically to .dropedmainnav and .dropedunderul, as well as using inline styles.

Answer №1

Have you considered using a function for each mouse enter/leave event instead of using $.each() in this scenario? It may be simpler and more efficient:

$(".main-nav ul li").mouseenter(function() {
      $(this).children('dropedmainnav').fadeIn(500);
     }
 }).mouseleave(function() {
      $(this).children('dropedmainnav').fadeOut(500);  
     }
 });

Answer №2

Unsure of the specific goal you're aiming for, but it's possible to eliminate the use of jQuery entirely. All animations and mouse-over effects can be achieved using just CSS (utilizing :hover). Feel free to try out the code snippet provided below and let me know if it aligns with your needs.

body { font-family: arial; }

.onhover {-webkit-transition: all 0.5s; -moz-transition: all 0.5s; -ms-transition: all 0.5s; -o-transition: all 0.5s; transition: all 0.5s;}

li       .onhover { height: 0; width: 200px; overflow: hidden; border: 1px solid transparent; }
li:hover .onhover { height: 20px; border-color: #ccc; }
<div>
  <ul>
    <li>
      <div>Item 1</div>
      <div class="onhover">You are hovering item 1</div>
    </li>
    
    <li>
      <div>Item 2</div>
      <div class="onhover">You are hovering item 2</div>
    </li>
  </ul>
</div>
