如何在angularJS中将自动完成下拉列表作为网格？

Question

在这里,我创建了自动完成的示例,它工作正常,我需要对此进行一些修改.目前它的工作方式是这样的

但我真正需要的是我需要将下拉列表显示为网格视图.有些像这样

任何人都可以帮忙吗？谢谢

var app = angular.module('app', ['ui.bootstrap']);

正如我评论的那样,由于模板会针对suggestion.name您的示例数据集中的每一个重复,因此它将在每个列出的名称上方包含列标题.

更新:在之前的SO答案中找到的陪审团操作解决方案是注入angular的filterFilter,而不是使用$scope.sample_data重复的集合,而是基于$ viewValue创建预过滤的组.为了将数据集中的所有人员组合在一起,我向每个人添加了公司属性(在此处做出假设).然后,您可以initial = true在筛选数据集的第一个元素上设置指标属性(在本例中).

最后,在您的模板中,除了将typeahead属性值更改为之外suggestion.name for suggestion in filtered_sample_data($viewValue) | filter: $viewValue">,您ng-if还将在表头上设置一个仅在`match.model.initial'为true时显示的内容.

只要数据集中的每个人都具有一些与该集合中所有其他人具有相同值的通用属性,并且您按该属性进行分组,这将起作用.

[注意,过滤器使用lodash的隐式链接,所以我也为lodash.js添加了一个脚本标记.]

感谢@runTarm的解决方法.
