semanticUI侧边栏加下拉列表

Question

当我按下拉图标时，我的项目有问题，我的下拉项目被白色区域隐藏，图片更清晰。所以我想知道是否有人能达到我的期望，我将不胜感激。

以下是代码的一部分：

<div class="ui sidebar inverte top five item menu">

    <div class="item">
        <div class="ui dropdown item" id="hideden-dropdown">
            类目
            <i class="dropdown icon"></i>
            <div class="menu">
                <a href="#" class="item">Electronics</a>
                <a href="#" class="item">Electronics</a>
                <a href="#" class="item">Electronics</a>
            </div>
        </div>
    </div>

    <a class="item">
        2
    </a>
    <a class="item">
        3
    </a>
    <a href="#" class="item">4</a>
    <a href="#" class="item">5</a>
</div>

<div class="pusher">
    <div class="ui button" id="menu">
        menu
    </div>

    <button type="button" name="button" class="ui red button" id="tran-bun">TestDimmer</button>

    <div class="ui segment" id="test-tran" style="margin:10%;">

<script>
    $('#menu').click(function () {
