首先，我必须承认我不熟练使用PHP或JS，但到目前为止，除了以下内容之外我还能正常工作..
我正在构建一个页面，用户可以在其中提交论文的新想法。因此，根据想法（也称为主题），用户需要提交标题，描述，需要撰写论文的语言等。
鉴于每个用户有几个主题，我调用MySQL数据库并使用PFP显示当前提交的主题。但是，我以可折叠的格式显示主题：用户首先获取所有主题的列表，然后通过单击某个主题，该项扩展以显示主题的详细信息（在JS中使用$ content.slidetoggle（）语句）
这就是那个＆＃34;＆＃34;在用户点击某个主题后显示的是TinyMCE编辑器。那个编辑以非常奇怪的方式展示。例如，TinyMCE工具栏中的按钮很长，导致按钮超出编辑器本身的边界。它们还显示分布在多行中，工具栏的高度突然是文本编辑器本身的四倍。 我创建了一个JSFiddle来试图演示正在发生的事情：https://jsfiddle.net/joren_mar/5dmzx8b2/ 我已经截取了问题的截图： https://drive.google.com/file/d/0B6JG0538ekaZc294RFBxdXJraU0/view
我也试图谷歌类似的问题（例如：Why is my TinyMCE hidden textarea acting up?），但那些没有描述我遇到的问题。此外，我还尝试了大多数提出的解决方案，但似乎都没有。
感谢您帮助我！
