如何保持打开< select> 下拉菜单以测试Firebug中的样式?

How to keep <select> dropdown open to test styles on in firebug?

我正在尝试设置< option>

<select class="select">
    <option selected>Select</option>
    <option>Blue</option>
    <option >Red</option>
    <option>Green</option>
    <option>Yellow</option>
    <option>Brown</option>
</select>

但是每次我需要打开并查看在Firebug中更改CSS之后发生了什么.我知道打开查看结果并不需要花费很多时间.

But every time i need to open and see what's happening after changing css in firebug. I know it doesn't take much time to open an see the result.

但是我只是想知道是否有任何技巧可以使下拉菜单保持打开状态

But I'm just curious to know if there is any trick to keep the dropdown open
