Question

我创建了一个模态，在模态体中我想添加一个下拉按钮。

但由于某种原因，下拉是在完全错误的地方，我已经尝试在css中写它但无济于事

我先尝试过这个

<div class="modal-content">
  <div class="modal-header">
    <span class="close">×</span>
    <h2 align="left"><img src="/pic"width="50px" height="50px" />Share</h2>
  </div>
  <div class="modal-body">
    <input type="textarea" align="left" id = "shareSearchBar"  placeholder ="" name = "search">

    <div class="dropdown">
      <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
        <img src="pic2"width="20px" height="20px" />Edit
        <span class="caret"></span>
      </button>
      <ul class="dropdown-menu  " aria-labelledby="dropdownMenu1">
        <li><a href="#" data-value="action"><img src="/pic"width="20px" height="20px" />E</a></li>
        <li><a href="#" data-value="another action"><img src="/pic"width="20px" height="20px" />V</a></li>
      </ul>
    </div>

我的css试图将按钮移动到正确的位置。

#dropdownMenu1 {
    position: absolute;
    top: 35%;
    right: 3%
}

.dropdown {
    position: absolute;
    top: 35%;
    right: 0%
}

然后我尝试了下面的非常相似但有点不同的内容

  <div class="modal-body">
    <button type="button" id = "dropdownMenu1" class="btn btn-small btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
      <img src="/pic"width="20px" height="20px" />Edit
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
      <li><a href="#" data-value="action"><img src="/pic"width="20px" height="20px" />e</a></li>
      <li><a href="#" data-value="another action"><img src="/pic"width="20px" height="20px" />v</a></li>
    </ul>
  </div>
</div>

相同的CSS ...

我真的无法看到这个。

你能否重新启动你在模特秀节目中的下拉菜单。像这样：

$('#mymodal').on('shown', function() {
        $("#mydropdown").dropdown();
    });

并删除您的自定义CSS。

事件和initiliaze语法可以根据bootstrap的版本而改变。
