<p>In order to use jQuery Easy Columns, you must install it as you would any other jQuery plugin.  First, download the zip file using the button above.  After downloading the file, extract it to a location of your choice, and move the extracted folder to your server using your favorite FTP client.  After moving the plugin to your server (and of course calling the jQuery source into your document), call it in on your site using the following snippet of code:</p>
<pre>
&lt;script type=&quot;text/javascript&quot; src=&quot;/path/to/jquery.easycolumns.js&quot;&gt;&lt;/script&gt;

#3 楼

我遇到了与OP类似的问题，但对我来说，将<h1>保留在<div>中存在一个问题。 br />每次切换标签<h1>都不见了。我做了很多搜索，对于Wordpress 4.7.3，我发现那里有很多过时的修复程序。市长将TinyMCE从版本3升级到了版本4。针对v.3的解决方案不适用于v.4。我的情况：


安装高级TinyMCE配置插件
将TinyMCE valid_children设置设置为+div[h1],h1[div]

我另外配置了indent=true，forced_root_block=false和schema=html5（当我阅读时forced_root_block说明我将其理解为wpautop的替代品）

结果我得到了它（它可以抵抗制表符切换）
