Tooltip on select box options

I have a select box in which the options have policy name. I need to display the description of policies in tool tip of the options. I tried tipr plugin where data-tip option is used for this. It works fine for div, span etc but not for select box option. I also tried normal method that I attached in the above link. This works only when the drop down is open by default .

<div>
    <h4>Default behaviours</h4>
    <select>
        <option title=""></option>
        <option title="1">1</option>
        <option title="2">2</option>
        <option title="3">3</option>
        <option title="4">4</option>
    </select>

    <select multiple>
        <option title=""></option>
        <option title="1">1</option>
        <option title="2">2</option>
        <option title="3">3</option>
        <option title="4">4</option>
    </select>
</div>

<div>
    <h4 class='uitip' title='Tests with jQuery UI Tooltips applied'>jQuery UI tooltips</h4>
    <select class='uitip' title='has tooltips'>
        <option title=""></option>
        <option title="1">1</option>
        <option title="2">2</option>
        <option title="3">3</option>
        <option title="4">4</option>
    </select>

    <select multiple class='uitip' title='has tooltips'>
        <option title=""></option>
        <option title="1">1</option>
        <option title="2">2</option>
        <option title="3">3</option>
        <option title="4">4</option>
    </select>
</div>

Any suggestions please?

You must specify a container for tooltip outside select, because tooltip is rendered inside select and is ignored by browser. As is specified in twitter bootstrap documentation tooltips are by default disabled you must enable it by yourself. http://getbootstrap.com/javascript/#four-directions See an working example below or https://jsfiddle.net/5xj10efa/
