Question

The slideToggle() function appears to be malfunctioning when sliding up or down, as it

Currently, I am in the process of creating a dropdown menu. However, I am facing an issue where the menu does not slide down or up smoothly when clicked. The animations seem to be delayed or non-existent.

$('.menu-vertical .nav-menu > li').on('click', function(e) {
  e.preventDefault();
  $(this).find('ul').slideToggle('2000', 'swing');
});

.menu-vertical .nav-menu li ul {
  position: relative;
  background: #f5f5f5 !important;
  top: 0;
  display: none;
  transition: all .4s ease;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<nav class="menu-vertical">
  <ul class="nav-menu">
    <li>this is head
      <ul>
        <li>this is one</li>
        <li>this is one</li>
        <li>this is one</li>
        <li>this is one</li>
      </ul>
    </li>
    <li>head is head</li>
    <li>head is head</li>
  </ul>
</nav>

Answer №1

It seems like there might be an issue with conflicting transitions in your CSS.

Additionally, make sure that the timing value for the slide is a number and not a string. Using a string will default to 400ms instead of the specified 2000ms.

$('.menu-vertical .nav-menu > li').on('click', function(e) {
  e.preventDefault();
  $(this).find('ul').slideToggle(2000, 'swing'); // change '2000' to 2000
});

.menu-vertical .nav-menu li ul {
  position: relative;
  background: #f5f5f5 !important;
  top: 0;
  display: none;
  /*transition: all .4s ease; <- remove this bit*/
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<nav class="menu-vertical">
  <ul class="nav-menu">
    <li>this is head
      <ul>
        <li>this is one</li>
        <li>this is one</li>
        <li>this is one</li>
        <li>this is one</li>
      </ul>
    </li>
    <li>head is head</li>
    <li>head is head</li>
  </ul>

The issue stems from the absence of the crucial $(document).ready() event handler.

$(document).ready(function() { //forgot this very important
  $('.menu-vertical .nav-menu > li').click(function(e) {
    e.preventDefault();
    $(this).find('ul').slideToggle(2000, 'swing');
  });
});

.menu-vertical .nav-menu li ul {
  position: relative;
  background: #f5f5f5 !important;
  top: 0;
  display: none;
}

menu-vertical .nav-menu li ul {
  position: relative;
  background: #f5f5f5 !important;
  top: 0;
  display: none;
  transition: **background** .1s ease-in;
}

I have updated the CSS code for your solution to only include specific properties for transition effects.

Instead of using "all" in the transition property, it's better to specify individual properties that you want to target for transitions.

Remember: The first parameter in the transition property should be a specific CSS property you want to animate.

For more information on the transition property, you can refer to this link:
