问题
I am using angular.js and bootstarp - angular-ui-bootstarp. and I found a problem that when using the select, even the option is not empty, the select in the page always show nothing until you click the option list. The first thing I tried is directly put options in the select, and make one option with ng-selected="selected", but no working
<select class=" input-sm pull-right" style="margin-right: 5px;" ng-change="selectUserFilter()" ng-model="user_filter_key" >
<option >All</option>
<option ng-selected="selected">Active</option>
</select>
The second thing I tried is to embedded a model with options list into the select, still not working
$scope.user_options = ['All','Active'];
<select class=" input-sm pull-right" style="margin-right: 5px;" ng-change="selectUserFilter()" ng-model="user_filter_key" ng-options="opt for opt in user_options">
</select>

Please see here http://jsbin.com/tifur/1/edit
just set user_filter_key in yyour controler by :
$scope.user_filter_key = $scope.user_options[0]
html:
<body ng-app="app">
<div ng-controller="firstCtrl">
<select class=" input-sm pull-right" style="margin-right: 5px;" ng-change="selectUserFilter()" ng-model="user_filter_key" ng-options="opt for opt in user_options">
</select>
</div>
</body>
JS:
var app = angular.module('app', []);
app.controller('firstCtrl', function($scope) {
$scope.user_options = ['All', 'Active'];
//add this
$scope.user_filter_key = $scope.user_options[0]
});
