Is there a way to show the "searching" message option using a single select element

一丶页面中的指令　　1.ng-if=“” 指令可根据true或者false来决定显示不现实该标签体内容　　2.ng-repeat 当循环的集合中的元素为map对象时,应当书写为 (key,value) in “angular变量集合名” 　　3.ng-true-value="1" ng-false-value="0" 一般用于复选框，选中值为1否则为0 ，搭配ng-model=“”使用，可将其复制0或1 　　4.ng-options=“item.id as item.name for item in list”性可以在表达式中使用数组或对象来自动生成一个select中的option列表。ng-options与ng-repeat很相似，很多时候可以用ng-repeat来代替ng-options。　　　　但是ng-options提供了一些好处，例如减少内存提高速度，以及提供选择框的选项来让用户选择。一般用于select中　　5.ng-bind-html指令用于显示html内容例如：<div class="attr" ng-bind-html="item.title | trustHtml"></div> ，搭配$sce服务，写出的过滤器trustHtml进行使用　　6. ng-checked=“” 指令控制复选框的勾选状态
