具有100%宽度的引导格式的SelectBoxIt输入

Question

我使用SelectBoxIt输入(http://gregfranko.com/jquery.selectBoxIt.js/)在引导3水平形式。我希望输入随着表单的宽度而增长和折叠，但是当将宽度设置为100%时，它们最终会崩溃。

我创建了一个JSFiddle来展示我的问题，并想知道是否有人擅长CSS，可以提出解决方案或建议吗？

CSS

.selectboxit-container .selectboxit-options,
.selectboxit-container .selectboxit
{
    width: 100%;
}

.col-xs-8,
.col.sm-8,
.col-md-8,
.col-lg-8
{
    border: 1px solid black;
}

Javascript

$("select").selectBoxIt({
    autoWidth: false
});

将容器包含在第一条规则中：

.selectboxit-container .selectboxit-options,
.selectboxit-container .selectboxit,
.selectboxit-container {
    width: 100%;
}
