CSS不适合组织结构图（用ul和li结构）

Question

我正在使用html和css创建组织结构图，但图表的右侧格式不正确。销售，生产1，生产2应归联合董事所有，但它低于左侧列表。右侧连接器也没有正确连接。

我的图表应如下所示

                        Director
                             |
    (1)Joint Director(Account)               (2)Joint Director
                |                                 |
(1)Accountant1    (2)Accountant2     (1)Sales  (2)Production1 (3)Production3
                                          |
                                (1)Sales1  (2)Sales2  (3)Sales3

但它看起来像这样： https://smilestechno.000webhostapp.com/My/tree.html

HTML

<div class="tree">
    <ul>
        <li><a href="#">Director</a>
            <ul>
                <li><a href="#">Joint Director(Account)</a>
                    <ul>
                        <li><a href="#">Accountant 1</a></li>
                        <li><a href="#">Accountant 2</a></li>

Answer 1

你不能把另一个ul作为ul的孩子。正确的结构是

<ul>
  <li>
    <ul>
      <li></li>
    </ul>
  </li>
</ul>

  

答案

 ...
 <li><a href="#">Joint Director</a> <!-- remove </li> here -->
     <ul>
         <li><a href="#">Sales</a> <!-- good here -->
             <ul>
                 <li><a href="#">Sales1</a></li>
                 <li><a href="#">Sales2</a></li>
                 <li><a href="#">Sales3</a></li>
             </ul>
          </li>
          <li><a href="#">Production1</a></li>
          <li><a href="#">Production2</a></li>
     </ul>
   </li> <!-- add </li> here -->

Answer 2

在你的代码中关闭li标签没有放置正确的结构。使用下面的代码它对我来说很好。

<div class="tree">
    <ul>
        <li><a href="#">Director</a>
            <ul>
                <li><a href="#">Joint Director(Account)</a>
                    <ul>
                        <li><a href="#">Accountant 1</a></li>
                        <li><a href="#">Accountant 2</a></li>
                    </ul>

                </li>
                <li><a href="#">Joint Director</a>
                    <ul>
                        <li><a href="#">Sales</a>
                            <ul>
                                <li><a href="#">Sales1</a></li>
                                <li><a href="#">Sales2</a></li>
                                <li><a href="#">Sales3</a></li>
                            </ul>
                        </li>
                        <li><a href="#">Production1</a></li>
                        <li><a href="#">Production2</a></li>
                    </ul>
                  </li>
            </ul>

        </li>
    </ul>
