显示 jquery UI 自动完成功能，其中类别水平而不是垂直

Question

我正在尝试水平显示自动完成结果，而不是默认(垂直(。我能够做到这一点，但问题是我无法再从下拉列表中选择该项目。我想是因为我用了div 而不是 ul。如果我使用 ul jquery 会内联附加一些不需要的类。这扰乱了水平行为

.HTML

  <label for="search">Search: </label>
<input id="search">

.CSS

#search {
    width: 500px;
  }
 .ui-autocomplete {
    display: flex;
    width: auto !important;
}
.ui-autocomplete-category {
    font-weight: bold;
    padding: .2em .4em;
    margin: .8em 0 .2em;
    line-height: 1.5;
  }
  .ui-autocomplete-category ul{
    padding:0;
  }
  .submenu {
    font-weight: normal;
  }

.JS

$.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, submenuUl;
        if ( item.category != currentCategory ) {
             var elt = $("<li class='ui-autocomplete-category'>" + item.category + "</li>");
             var submenu = $("<div class='submenu "+ item.category +"'></div>");
             elt.append(submenu);
             ul.append(elt);
             currentCategory = item.category;
          }
          submenuUl = ul.find("."+item.category+"");
          li = that._renderItemData(submenuUl, item );
          if ( item.category ) {
            li.attr( "aria-label", item.category + " : " + item.label );
          }
      });
    }
  });

这就是我喜欢的小部件！

主要错误是没有ul作为自定义li的直接父级。
然后，那些自定义li需要ui-menu-item类才能被选中......

最后，您必须使用 !important ">覆盖">嵌套ul的样式。因此，它们将显示为具有relative位置的block。顺便说一句，没有边界...

我删除了一个奇怪显示的图标...

它在CodePen中工作正常。它需要一个额外的 CSS 规则才能在下面的代码片段中工作。(不要问我为什么！

$.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, submenuUl;
      if ( item.category != currentCategory ) {
        var elt = $("<li class='ui-autocomplete-category'>" + item.category + "</li>");
        var submenu = $("<div class='submenu "+ item.category +"'><ul></ul></div>");  // Added <ul></ul>
        elt.append(submenu);
        ul.append(elt);
        currentCategory = item.category;
      }
      submenuUl = ul.find("."+item.category+" ul"); // added +" ul"
      li = that._renderItemData(submenuUl, item );
      if ( item.category ) {
        li.attr( "aria-label", item.category + " : " + item.label ).addClass("ui-menu-item"); // Added the addClass()
      }
    });
  }
});
// Actual Code
$(function() {
  var data = [
    { 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" }
  ];
  $( "#search" ).catcomplete({
    delay: 0,
    source: data,
    select: function(item, ui){ // Added item, ui --- Arguments were missing.
      console.log(ui.item.value);
      $( "#search" ).val( ui.item.value );
      return false;
    }
  });	
});
