blocks|key|382635|text|您需要将工具提示添加到每个生成的li元素中，而不是option元素(在初始化bootstrap-select之后)。您可以使用li访问生成的data('selectpicker')元素。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|382636|$('#selectID').data('selectpicker').$lis.attr('title',+'New+Title').tooltip();|code-block|syntax|javascript|382637|entityMap^0|G|2|P|6|12|G|1R|2|1Y|K|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|L|$]]

You will need to add the tooltip to each generated <code>li</code> element, rather than the <code>option</code> elements (after <code>bootstrap-select</code> is initialized). You can access the generated <code>li</code> elements using <code>data('selectpicker')</code>.

<pre><code>$('#selectID').data('selectpicker').$lis.attr('title', 'New Title').tooltip();
</code></pre>

blocks|key|382644|text|这是一种稍微不同的方法，它将工具提示属性从选项中泵出，并将它们放到引导行中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|382645|var+tips+=+[];
$('#selectID+option').each(function(){
++++tips.push($(this).attr('tooltip'));

This is a little different way to do it that will pump the tooltip attribute off the options and put them on to the bootstrap rows

<pre><code>var tips = [];
$('#selectID option').each(function(){
 tips.push($(this).attr('tooltip'));
});

$('#selectID').data('selectpicker').$lis.each(function(i){
 $(this).attr('title',tips[i]).tooltip() 
});
</code></pre>

blocks|key|397434|text|工具提示在bs+select中不动态工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|397435|它给所有的选择项相同的值“测试”，但当移动鼠标应该改变。|397436|$('#id').on('shown.bs.select',+function+()+{

Tooltip does not work dynamically with bs select.

It gives all select item same value "test", but when move the mouse should be changed.

<pre><code>$('#id').on('shown.bs.select', function () {
 var test = $('selectpicker').selectpicker.current.elements.text();
 $($(this).data('selectpicker').selectpicker.current.elements).attr('title', test ).tooltip();
});
</code></pre>

blocks|key|1552990|text|我对Sovtek的答案进行了一些修改，这次使用选项中定义的title属性，并将其设置为生成的Bootstrap-select元素的标题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1552991|var+tips+=+[];

++++tips.push($(this).attr('title'));

I got Sovtek's answer working with some modification, this time taking the title attribute defined in the option(s) and setting it to the title of the generated Bootstrap-select
element:
<pre><code>var tips = [];
$('#mySelectPickerID option').each(function () {
 tips.push($(this).attr('title'));
});

$('.bootstrap-select .dropdown-menu li a span.text').each(function (i) {
 $(this).attr('title', tips[i]);
});
</code></pre>

blocks|key|1553017|text|RBILLC的答案对我有效，但是对于那些不想使用js解决方案的人，您可以使用data-content+(参考)属性将引导title插入到元素div/span中|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1553018|前任：|1553019|++<select+class="selectpicker">

++</select>|code-block|syntax|javascript|1553020|注意事项：data-content输入将通过引导选择进行清理，因此在上面的示例中，您需要在div标记(参考)上添加title属性。|BOLD|1553021|var+extendBootstrapSelectSanitizer+=+$.fn.selectpicker.Constructor.DEFAULTS.whiteList;

RBILLC's answer worked for me but for those who doesn't want to use js solution, you can use <code>data-content</code> (<a href="https://developer.snapappointments.com/bootstrap-select/examples/#custom-content" rel="nofollow noreferrer">ref</a>) attribute to insert bootstrap <code>title</code> into your element <code>div</code>/<code>span</code>
For ex:
<pre><code> &lt;select class=&quot;selectpicker&quot;&gt;
 &lt;option title=&quot;Option with tooltip&quot; data-content=&quot;&lt;div title='I am your tooltip'&gt;&lt;span&gt;Option with tooltip&lt;/span&gt;&lt;small class='text-muted'&gt;subtext 1...&lt;/small&gt;&lt;/div&gt;&quot;&gt;&lt;/option&gt;
 &lt;option data-subtext=&quot;subtext 1...&quot;&gt;Option with tooltip&lt;/option&gt;
 &lt;/select&gt;
</code></pre>
Note: <code>data-content</code> input will be sanitized by bootstrap-select, so in above example, you will need to whitelist <code>title</code> attribute on <code>div</code> tag (<a href="https://developer.snapappointments.com/bootstrap-select/options/#sanitizer" rel="nofollow noreferrer">ref</a>)
<pre><code>var extendBootstrapSelectSanitizer = $.fn.selectpicker.Constructor.DEFAULTS.whiteList;
// To allow div elements and title attributes on td elements
extendBootstrapSelectSanitizer.div = ['title'];
</code></pre>

Silviomoreto bootstrap-select add to select <code>"display:none"</code>: 

<img src="https://i.stack.imgur.com/ufHJ1.jpg" alt="enter image description here"> 
and it make visible 'ul' like this:

<img src="https://i.stack.imgur.com/PBv16.jpg" alt="enter image description here">

I change this select dynamically:

<pre><code>for(var key in value) {
 $(this)
 .append($("&lt;option&gt;&lt;/option&gt;")
 .attr("value", key)
 .text(value[key])); 
} 
$(this).selectpicker('refresh');
</code></pre>

How can I dynamically add a tooltip to each option?
