Question

我试图水平显示自动完成结果，而不是默认值（垂直）。我能够做到，但问题是我无法从下拉列表中选择项目。我认为是因为我使用div而不是ul。如果我使用ul，jquery将内联一些不需要的类。弄乱了水平行为

HTML

    function preload() {
      this.load.image('sky', 'file:///home/chronos/u-fc7808c01e889e74148d1013b69f0a2241def976/Downloads/testprogram-atom.js/assets/sky.png');
      this.load.image('ground', 'assets/platform.png');
      this.load.spritesheet('dude', 'assets/dude.png');
      this.load.image('star', '/home/jojobinks/Desktop/testprogram-atom.js/star.png');
    }
    function create() {
      this.add.image(0, 0, 'sky');
    }
    function update() {

    }




    var config = {
      type: Phaser.AUTO,
      width: 800,
      height: 600,
      backgroundColor: '#FF0000',
      physics: {
        default: 'arcade',
        arcade: {
          gravity: {y:200},
          debug: false
        }
      },
    scene: {
      preload,
      create,
      update
    },

    }

    var game = new Phaser.Game(config);

那是我喜欢的小部件tweeking！

主要错误是没有<=作为自定义ul的直接父代。
然后，那些自定义li需要li类才能被选中...

最后，您必须使用ui-menu-item “覆盖” 嵌套ul的样式。因此它们将显示为!important，位置为block。顺便说一句，没有边界...

我删除了一个奇怪地显示...的图标

它在CodePen中工作正常。它需要附加的CSS规则才能在以下代码段中运行。 （不要问我为什么！）

relative

$.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;
    }
  });	
});

#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;
}

/* ADDED STYLE */
.ui-autocomplete>li>div>ul{
  display: block !important;
  position: relative !important;
  border: 0 !important;
}
span.ui-menu-icon{
  display:none !important;
}

/* ADDED for the SO snippet only !! Not needed on CodePen */
.ui-autocomplete>li{
  display: inline-block !important;
}
