JQuery自动填充 - 限制选择数量

Question

我正在使用JQUERY自动填充功能，并尝试将选项数限制为10。我不确定如何限制用户看到的内容。任何人都可以帮忙吗？

下拉列表最多只能显示10个名字......我不知道如何实现这一目标。在输入1个字符后激活自动完成功能。

$(function() {


     $( "#search" ).autocomplete({
        source:[
               {"label":"ALEX - A111","movie_id":"A111","name":"ALEX"},
               {"label":"AL - A112","movie_id":"A112","name":"AL"},
               {"label":"JON - A113","movie_id":"A113","name":"JON"},
               {"label":"JOE - A114","movie_id":"A114","name":"JOE"},
               {"label":"TOM - A115","movie_id":"A115","name":"TOM"},
               {"label":"TED - A116","movie_id":"A116","name":"TED"},

               ],


        minLength: 1, //search after one characters


        focus: function(event, ui) {
            $("#search").val(ui.item.label);
            return false;
        },

        change: function(event, ui) {
                if (!ui.item) {
                     alert("You must select a 'Member' from the drop-down list.");
                     $("#search").val('');
                     $("#search").focus();
                     $("#name").val('');
                return false;
                }
         },

        select: function( event, ui ) {
                    event.preventDefault();
                    $('#search').val(ui.item.label);
                    this.value = ui.item.label;

                    $('#name').val(ui.item.movie_id);

        }
    });
});
