我正在尝试修改此示例http://waynegm.github.io/imgNotes/examples/basic_interactive.html# 当用户单击图像时，为了使选择选项显示在对话框内。目前，代码在用户在编辑模式下选择的区域上放置一个标记，并打开一个对话框，允许他们输入文本，并带有保存/取消选项。 在对话框中，我想将textarea更改为选择列表，如：
<select>
<option value="head">Head</option>
<option value="leftarm">Left Arm</option>
<option value="rightarm">Right Arm</option>
<option value="leg">Leg</option>
</select>
看起来它应该是一个简单的改变，我已经制作了其他样本，其中单击图像上的简单使下拉出现。但是这个例子还有我需要的所有东西，比如删除和记录地点标记的共同点的选项。 当前的HTML：
