Exploring Alternative Methods to Navigate Through Elements Using JQuery UI Autocomplete

After testing two different approaches:

<div id = "team-search-container">
    <label for="team-search" class = "text-center">
         <input type = "text" id = "team-search">
    </label>
</div>

With the following code snippet:

$( "#team-search" ).catcomplete({
    delay: 0,
    source: teamdata,
    appendTo: '#team-search-container'
});

The div expands to display the elements, creating a layout similar to this: (Link to image) (The text ComboBox elements should read Autocomplete elements instead)

However, omitting the appendTo option as shown below:

$( "#team-search" ).catcomplete({
    delay: 0,
    source: teamdata
});

The functionality remains intact, but it generates empty space at the end of the page equal to the height of the autocomplete feature. The CSS utilized is:

.ui-autocomplete{
    position: relative;
    max-height: 300px;
    overflow-y: auto;
    overflow-x: hidden;
    padding-right: 20px;
}

.ui-autocomplete-category{
    font-size: 18px;
    list-style: none;
    width: 200px;
}

.ui-menu-item{
    list-style: none;
    width: 200px;
    cursor: default;
    background-color: #565656;
}

.ui-helper-hidden-accessible {
    display: none;
}

Due to the specified max-height being set as 600px, not appending anything will result in a surplus of 600px blank space at the page bottom, despite displaying the autocomplete directly beneath the search bar.

Answer №1

After examining the example you shared, I have not encountered the issue as described by you. Here is a snippet of the code:

$(function() {
  $.widget("custom.catcomplete", $.ui.autocomplete, {
    _create: function() {
      this._super();
      this.widget().menu("option", "items", "> :not(.ui-autocomplete-category)");
    },
    _renderMenu: function(ul, items) {
      var that = this,
        currentCategory = "";
      $.each(items, function(index, item) {
        var li;
        if (item.category != currentCategory) {
          ul.append("<li class='ui-autocomplete-category'>" + item.category + "</li>");
          currentCategory = item.category;
        }
        li = that._renderItemData(ul, item);
        if (item.category) {
          li.attr("aria-label", item.category + " : " + item.label);
        }
      });
    }
  });
  
  var data = [{
      label: "anders",
      category: ""
    },
    {
      label: "andreas",
      category: ""
    },
    {
      label: "antal",
      category: ""
    },
    {
      label: "annhhx10",
      category: "Products"
    },
    {
      label: "annk K12",
      category: "Products"
    },
    {
      label: "annttop C13",
      category: "Products"
    },
    {
      label: "anders andersson",
      category: "People"
    },
    {
      label: "andreas andersson",
      category: "People"
    },
    {
      label: "andreas johnson",
      category: "People"
    }
  ];

  $("#team-search").catcomplete({
    delay: 0,
    source: data,
    appendTo: '#team-search-container'
  });
});
.ui-autocomplete {
  position: relative;
  max-height: 300px;
  overflow-y: auto;
  overflow-x: hidden;
  padding-right: 20px;
}

.ui-autocomplete-category {
  font-size: 18px;
  list-style: none;
  width: 200px;
}

.ui-menu-item {
  list-style: none;
  width: 200px;
  cursor: default;
  background-color: #565656;
}

.ui-helper-hidden-accessible {
  display: none;
}
