html - 将图像添加到 Bootstrap 选择？

Question

我有一个 7x7px 的图像，我想在我的页面的每个选择选项旁边添加。 我需要在 CSS 中添加图像还是可以在 HTML 中添加？我也想要文本左侧的图像。我也尝试添加图像，但这只会弄乱样式。 感谢您的帮助!

<ul class="dropdown-menu">

            <a href="#">Green</a>
        </li>
    </ul>

<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">Image Droprdown
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <li>
      <a href="#">

备选方案:

var shownnn = "yes";
var dropd = document.getElementById("image-dropdown");

function showww() {
  dropd.style.height = "auto";
  dropd.style.overflow = "y-scroll";
}

function hideee() {
    dropd.style.height = "30px";
    dropd.style.overflow = "hidden";
  }
  //dropd.addEventListener('mouseover', showOrHide, false);
  //dropd.addEventListener('click',showOrHide , false);


function myfuunc(imgParent) {
  hideee();
  var mainDIVV = document.getElementById("image-dropdown");
  imgParent.parentNode.removeChild(imgParent);
  mainDIVV.insertBefore(imgParent, mainDIVV.childNodes[0]);
}

#image-dropdown {
  display: inline-block;
  border: 1px solid;
}
#image-dropdown {
  height: 30px;
  overflow: hidden;
}
/*#image-dropdown:hover {} */

#image-dropdown .img_holder {
  cursor: pointer;
}
#image-dropdown img.flagimgs {
  height: 30px;
}
#image-dropdown span.iTEXT {
  position: relative;
  top: -8px;
}

<!-- not tested in mobiles -->

<div id="image-dropdown" onmouseleave="hideee();">
  <div class="img_holder" onclick="myfuunc(this);" onmouseover="showww();">
    <img class="flagimgs first" src="http://www.google.com/tv/images/socialyoutube.png" /> <span class="iTEXT">First</span>
  </div>
  <div class="img_holder" onclick="myfuunc(this);" onmouseover="showww();">
    <img class="flagimgs second" src="https://cdn1.iconfinder.com/data/icons/thincons/100/menu-128.png" /> <span class="iTEXT">Second</span>
  </div>
  <div class="img_holder" onclick="myfuunc(this);" onmouseover="showww();">
    <img class="flagimgs second" src="http://www.google.com/tv/images/lplay.png" /> <span class="iTEXT">Third</span>
  </div>
  <div class="img_holder" onclick="myfuunc(this);" onmouseover="showww();">
    <img class="flagimgs second" src="https://cdn1.iconfinder.com/data/icons/thincons/100/menu-128.png" /> <span class="iTEXT">Fourth</span>
