我正在尝试创建一个显示所有 Twitter Bootstrap 图标及其文本的选择框。因此我使用的是Bootstrap-Select Plugin。其中一张图像显示在列表中，但其余图像以某种方式隐藏。
为了获得所有列出的图标及其文本的列表，我必须进行哪些更改？
JS：
<script src="source/bootstrap_select/bootstrap-select.js" type="text/javascript"></script>
<script type="text/javascript">
$( document ).ready(function() {
$('.selectpicker').selectpicker('');
});
</script>
HTML：
<select class="selectpicker">
<option data-icon="icon-search">icon-search</option>
<option data-icon="icon-envelope">icon-envelope</option>
<option data-icon="icon-heart" selected="selected">icon-heart</option>
