我正在尝试使用子菜单和搜索框进行下拉菜单。到目前为止,搜索字符串仅适用于第一级菜单,而不会查看第二级菜单项。有没有办法在第一级之外执行搜索? 最小的例子:
HTML:
<div class="ui segment">
<div class="ui search selection dropdown" id="test">
<span class="text">Search Selection</span>
<i class="dropdown icon"></i>
<div class="menu">
<div class="item">
<span class="text">Category 1</span>
</div>
<div class="item">
<i class="dropdown icon"></i>
<span class="text">Category 2</span>
<div class="menu">
<div class="item">Item 2A</div>
<div class="item">Item 2B</div>
<div class="item">Item 2C</div>
</div>
</div>
<div class="item">
<i class="dropdown icon"></i>
<span class="text">Category 3</span>
<div class="menu">
<div class="item">Item 3A</div>
<div class="item">Item 3B</div>
<div class="item">Item 3C</div>
</div>
</div>
</div>
</div>
</div>
JS:
$('#test')
.dropdown();
CSS:
.ui.selection.dropdown .menu {
overflow: visible !important;
}
