Accordian Expandable It Can Slide Down, But Wont Slide Up

here is the code, can someone help to modify? (function($){ $(document).ready(function() { // Categories menu opening // Categories menu opening $('.woocommerce.widget_product_cat

Solution 1:

To "toggle" element's visibility with sliding effect, you could use slideToggle.

Note that you need to remove :not(.opened) from the selector, because the handler won't work when this parent element has this class.

$(document).on("click", ".woocommerce.widget_product_categories .product-categories li.cat-parent > .cat-menu-close", function(e) {
  var $catParent = $(this).closest('li.cat-parent');
  var state = $catParent.hasClass('close');

  $catParent.toggleClass('opened', !state);

  $(this).nextAll('ul.children:first').slideToggle(state);
});

.cat-menu-close {
  cursor: pointer;
}

ul {
  list-style: none;
}

ul.children {
  display: none;
}

<div class="woocommerce widget_product_categories">
  <div class="product-categories">
    <ul>
      <li class="cat-parent">
        <span class="cat-menu-close">
          <button>Expand/collapse</button>
        </span>
        
        <div>Random sibling element</div>
        
        <ul class="children">
          <li>Child item</li>
          <li>Child item</li>
          <li>Child item</li>
        </ul>
      </li>
    </ul>
  </div>
