您只需将FontAwesome图标添加到选择下拉列表中即可。你只需要CSS中的一些东西，FontAwesome CSS和unicode。例如：
select {
font-family: 'FontAwesome', 'Second Font name'
}<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css" rel="stylesheet"/>
<select>
<option>Hi, </option>
<option>Hi, </option>
<option>Hi, </option>
<option>Hi, </option>
<option>Hi, </option>
</select>
单击图标时可以找到unicodes：Fontawesome
根据以下评论和issue on Github，select元素中的unicode将无法在OSX上运行。
更新：从Github issue开始，将multiple属性添加到select元素即可使其运行：
OSX El Capitan 10.11.4
- Chrome版本50.0.2661.75（64位）
- Sarafi 9.1版
- Firefox版本45.0.2
select{
font-family: FontAwesome, sans-serif;
}<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css" rel="stylesheet"/>
<select multiple>
<option> 500px</option>
<option> Adjust</option>
<option> Adn</option>
<option> Align-center</option>
<option> Align-justify</option>
<option> Align-left</option>
<option> Align-right</option>
</select>

我使用了此解决方案，并且可以与Font Awesome 5配合使用：https://stackoverflow.com/a/50973559/3813846
在我的案例中与众不同的是在课程中添加了font-weight: 900;。请记住，要“珍惜”价值。
我的代码示例：
<select class="text-primary fa-select" name="class_logo" required>
<option value="fa address-book"> address-book</option>
<option value="fa adjust"> adjust</option>
<option value="fa air-freshener"> air-freshener</option>
</select>
CSS：
.fa-select {
font-family: 'Lato', 'Font Awesome 5 Free';
font-weight: 900;
}

答案 5 :(得分：0)
我建议您使用Jquery插件selectBoxIt selectBoxIt
这很简单，你可以改变下拉菜单的箭头。
答案 6 :(得分：0)
使用显示所有选项的return redirect(url_for("result", the_final_value=predicted_output))
@app.route("/result")
def result(the_final_value):
return render_template("result.html", the_final_value=the_final_value)
标记时，可以使用<select>代替：
HTML
<div>支持JS
<div id='sectionOptionsSelect' size='5' class='block1'
style='visibility: hidden; border: 1px solid gray; padding: 5px; '>
<span class='addPageBreakAbove'>Add Page Break Above</span>
<span class='addPageBreakBelow'>Add Page Break Below</span>
<span class='removeSection'>
<label class='fa fa-window-close'
style='font-size: 25px; color: red; background: white; '></label>
Remove Section</span>
</div>
CSS
$('#sectionOptionsSelect span').hover(function () {
$(this).css('background', '#c0ec67');
}, function () {
$(this).css('background', 'transparent');
});
$('.removeSection').click(function () {
alert('removeSection');
});

另一种解决方案是在选择框上设置 size 属性。
从而从Apple样式中恢复对下拉菜单样式的控制，并正确显示Font Awesome Icons。
答案 8 :(得分：-1)
如果你想要插入符号，请删除＆＃34; appearence：none＆＃34;它意味着删除webkit和moz-以及css中的select。
