只有少数样式属性可以应用于 <option> 元素。

有些替换插件/库看起来像 <select> 但实际上是由常规的HTML元素组成可以

不,这是不可能的,因为这些元素的样式是由用户的操作系统处理的。 MSDN will answer your question here :

background-color 和 color

可以在某种程度上设置选项元素的样式。

使用 * CSS选择器您可以在系统绘制的框中设置选项的样式。

例子:

#ddlProducts *
{
 border-radius: 15px;
 background-color: red;
}

这里有一些风格的方法 <option> 以及 <select>

您仍然可以实现为每个 < 但可能需要对 < 也。我最喜欢的是下面提到的“Bootstrap Select”库。

如果您已经在使用引导,可以尝试 Bootstrap Select 图书馆

请注意,您可以设置整个 select 元素,或 option 元素分开。

示例 :

依赖项 jQuery查询 引导

兼容性 :不确定,但bootstrap说它“支持所有主要浏览器和平台的最新稳定版本”

演示 : https://developer.snapappointments.com/bootstrap-select/examples/

.special {
  font-weight: bold !important;
  color: #fff !important;
  background: #bc0000 !important;
  text-transform: uppercase;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<script src="https://cdn.jsdelivr.net/npm/bootstrap-select@1.13.9/dist/js/bootstrap-select.min.js"></script>

<select class="selectpicker">
  <option>Mustard</option>
  <option class="special">Ketchup</option>
  <option style="background: #5cb85c; color: #fff;">Relish</option>
</select>

选择2(JS lib)

有一个图书馆你可以用,叫做 Select2

依赖项

兼容性 :IE 8+、Chrome 8+、Firefox 10+、Safari 3+、Opera 10.6+

演示 https://select2.org/getting-started/basic-usage

还有一个 bootstrap theme 可用。

无引导示例:

$(function() {
  var $select = $('.select2');
  
  $select.select2({
    theme: 'paper'
  });
});

<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.7/css/select2.min.css" rel="stylesheet"/>

<select class="select2 form-control" placeholder="Country">

    <option value="HI">Hawaii</option>
  </optgroup>

    <option value="NV">Nevada</option>
    <option value="OR">Oregon</option>
    <option value="WA">Washington</option>
  </optgroup>
</select>

var$select=$('.select2');

$select.select2选择({

好像我可以为 select 直接在铬中。CSS和HTML代码如下:

.boldoption {
	font-weight: bold;
}

<select>
	<option>Some normal-font option</option>
	<option>Another normal-font option</option>
	<option class="boldoption">Some bold option</option>
</select>

如前所述,唯一的方法是使用一个插件 <select>

dy_ 10 年前

可以为某些属性设置样式 <option>

font-family
color
font-*
background-color

<选项> 标签,例如任何 google font , Material Icons 或其他图标字体 icomoon 或者类似的(对于字体选择器等来说可能很方便。)

考虑到这一点,您可以创建字体系列堆栈并在其中插入图标 <选项> 标签,例如。

    <select>
        <option style="font-family: 'Icons', 'Roboto', sans-serif;">a    âââ</option>
        <option style="font-family: 'Icons', 'Roboto', sans-serif;">b    ââââ</option>
    </select>

哪里 â 是从 Icons 其余的是从 Roboto .

请注意,尽管自定义字体不适用于mobile select。

实际上,您可以添加:before和:after并设置它们的样式。至少它是个东西

option {
  font-size: 18px;
  background-color: #ffffff;
}

option:before {
  content: ">";
  font-size: 20px;
  display: none;
  padding-right: 10px;
  padding-left: 5px;
  color: #fff;
}

option:hover:before {
  display: inline;
}

<select id="ddlProducts" name="ddProducts">
  <option>Product1 : Electronics </option>
  <option>Product2 : Sports </option>

现在是2017年,有可能针对特定的选择选项。在我的项目中,我有一个带有 ,选择选项位于表格单元格中 ,并且select具有一个ID 选择#pa#U颜色 . option=“附加” (在其他类标记中)。如果用户以批发客户身份登录,则可以看到所有颜色选项。但是零售客户不允许购买2种颜色,所以我禁用了它们

<option class="attached" disabled>color 1</option>
<option class="attached" disabled>color 2</option>

CSS格式

table.variations td.value select#pa_color option.attached:disabled {
display: none !important;
}

因此,我的颜色选择只有批发客户才能看到。

可以使用内联样式将自定义样式添加到 <option> 标签。

<option style="font-weight:bold;color:#09C;">Option 1</option> 这会将样式应用于此特定 <

然后您可以使用一点javascript魔术将内联样式应用到所有 < 内部元素 <select> 这样标记:

var select = $(document).getElementById('#select-element-id')

var option = select.children('#option-element-id')

option.css('font-weight', 'bold')

option.css('font-size', '24px')

你也可以使用 <option value="" disabled> <br> </option> 在选项之间添加换行符。

这肯定有用。不是通过html。这就是为什么CSS样式不起作用,。。通常地 option{font-size : value ; background-color:colorCode; border-radius:value; }
这将工作,但我们不能自定义的填充,边距等。。

下面的代码100%的工作,以自定义选择标签采取从 this example

var x, i, j, selElmnt, a, b, c;
/*look for any elements with the class "custom-select":*/
x = document.getElementsByClassName("custom-select");
for (i = 0; i < x.length; i++) {
  selElmnt = x[i].getElementsByTagName("select")[0];
  /*for each element, create a new DIV that will act as the selected item:*/
  a = document.createElement("DIV");
  a.setAttribute("class", "select-selected");
  a.innerHTML = selElmnt.options[selElmnt.selectedIndex].innerHTML;
  x[i].appendChild(a);
  /*for each element, create a new DIV that will contain the option list:*/
  b = document.createElement("DIV");
  b.setAttribute("class", "select-items select-hide");
  for (j = 1; j < selElmnt.length; j++) {
    /*for each option in the original select element,
    create a new DIV that will act as an option item:*/
    c = document.createElement("DIV");
    c.innerHTML = selElmnt.options[j].innerHTML;
    c.addEventListener("click", function(e) {
        /*when an item is clicked, update the original select box,
        and the selected item:*/
        var y, i, k, s, h;
        s = this.parentNode.parentNode.getElementsByTagName("select")[0];
        h = this.parentNode.previousSibling;
        for (i = 0; i < s.length; i++) {
          if (s.options[i].innerHTML == this.innerHTML) {
            s.selectedIndex = i;
            h.innerHTML = this.innerHTML;
            y = this.parentNode.getElementsByClassName("same-as-selected");
            for (k = 0; k < y.length; k++) {
              y[k].removeAttribute("class");
            }
            this.setAttribute("class", "same-as-selected");
            break;
          }

此元素由操作系统呈现,而不是由HTML呈现。它不能通过CSS设置样式。

	$(function() {
    var clicky;
    var t=0;
    $(document).mousedown(function(e) {
        clicky = $(e.target);
    });
    $(document).mouseup(function(e) {
        clicky = null;
    });

    $("select").focusout(function(e) {
        if (typeof clicky.attr('id') !== typeof undefined && clicky.attr('id') !== false) {
        	$(this).parents().children("span.selected").html(clicky.html());
        	$(this).children('option[value="'+clicky.attr('id')+'"]').prop('selected', true);
		}
        
        $(this).parents().children("span.lists").html('');
        

    });
    $('select > option').text(function(i, text) {
				var attr = $(this).attr('selected');
				if (typeof attr !== typeof undefined && attr !== false) {
        				$(this).parents().parents().children("span.selected").html(text);
				}
	});

		$("select").focusin(function(){
			$(this).children('option').text(function(i, text) {
    			$(this).parents().children("span.lists").append("<span class='item' id='"+$(this).attr('value')+"'>"+text+"</span>");
				});
		});

	});

select {
  width: 0px;
  height: 0px;

您可以添加一个类并给出字体-weight:700; 在选项中。但通过使用这个,所有的文字都会变得粗体。

有没有办法不使用代码来更改<select>所选项目的文本颜色[[副本]

选择2(JS lib)

MDBootstrap($&引导和;(JQuery)
