我正在采用dashboard來自https://getbootstrap.com/docs/5.0/examples/dashboard/的示例作為自定義頁面。我現在正在嘗試添加一個li元素（或第二個ul），它貼在側邊欄的底部。li應包含一個在側邊欄的整個寬度上延伸的按鈕。我已經嘗試添加fixed-bottom用于將li元素放置在底部的元素，但按鈕 ( width: 100%) 現在延伸到整個頁面。所以我不確定是否fixed-buttom是正確的方法。
<div class="row">
<nav id="sidebarMenu" class="col-md-3 col-lg-2 d-md-block bg-light sidebar collapse">
<div class="position-sticky pt-3">
<ul class="nav flex-column mb-2">
<li class="nav-item">1</li>
<li class="nav-item">2</li>
<li class="nav-item">3</li>
</ul>
<!-- this shall be sticky at the bottom of the sidebar -->
<ul class="nav flex-column mb-2 fixed-bottom">
<li>
<div class="btn-group dropup" style="width:100%">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">my button</button>
<ul class="dropdown-menu">
<li class="nav-item">1</li>
<li class="nav-item">2</li>
</ul>
</div>

</ul>

uj5u.com熱心網友回復：
干得好...
基本上，制作兩個div元素 (upper_part和lower_part)。添加以下 CSS：
#upper_part {
height: 80%; /* 80% 20% = 100% */
}
#lower_part {
height: 20%; /* 80% 20% = 100% */
padding: 3%;
padding-bottom: 10%;
}
.my_button {
width: 100%; /* Make the button full-width. */
}
請參閱下面的片段。

font-size: .875rem;
