这里要注意jquery要放在select2的前面。
2、一些实例
Document
.select2-dropdown {
margin-left: 8px !important;
margin-top: 20px !important;
}
这是单选例子

duplicate
$(document).ready(function() {
$(".js-example-basic-single").select2(); //单选
$(".js-example-basic-multiple").select2(); //多选
$(".js-example-placeholder-single").select2({ //允许清除
placeholder: "Select a state", //默认提示语
allowClear: true
});
$(".js-example-placeholder-multiple").select2({
placeholder: "Select a state" //默认提示语
});
var data = [{
id: 0,
text: 'enhancement'
}, {
id: 1,
text: 'bug'
}, {
id: 2,
text: 'duplicate'
}, {
id: 3,
text: 'invalid'
}, {
id: 4,
text: 'wontfix'
}];
$(".js-example-data-array").select2({
data: data
})
$(".js-example-data-array-selected").select2({
data: data
})
});
