angular.js - I want to use angular to simulate the select drop-down box effect, as shown below, but I don't know how to achieve it?

Question

When the user clicks on the p (A) of "Wuhan", a drop-down box p (B) will appear. The content in B is dynamically generated. Then click on any content in B, and then assign it to A. area, and then B is hidden.

Answer 2

controller：

$scope.names = [{
    name: 'tom'
},{
    name: 'jack'
},{
    name: 'xiaoming'
}];

html

<p>
    <select ng-options="names.name for names in names">
        <option value="">请选择</option>  <!-- 直接用模型值第一个会为空，所以这里填充第一个 -->
    </select>
</p>
