This plugin is currently aimed at developers so it doesn’t come with any CSS or JavaScript, it just ads the DIVs for the columns, the rest is up to the developer’s imagination. This will allow developers to easily add column functionality to custom WordPress implementations.
<h3>Usage</h3>
How do users use it?
To split the content into columns, you simply add the shortcode [columnbreak] where you want the one column to end and the next one to start.
It will add a container around the columns with the class ‘ninja_columns’ and the class ‘colsid_{post-id}’ that will allow you to target the post or page specifically.

Ninja Columns

The plugin will allow users to easily split content into columns using short-codes.

Bamboo Manchester

This plugin provides several shortcodes for organising your content into multi-column layouts. It supports two, three and four column layouts and allows for content to span multiple columns if required.
Usage
Insert the required shortcodes into your content as follows:
2 column layout:
<pre><code> [column-half-1]
 First column of content
 [/column-half-1]
 [column-half-2]
 Second column of content
 [/column-half-2]
</code></pre>
3 column layout:
<pre><code> [column-third-1]
 First column of content
 [/column-third-1]
 [column-third-2]
 Second column of content
 [/column-third-2]
 [column-third-3]
 Third column of content
 [/column-third-3]
</code></pre>
4 Column layout:
<pre><code> [column-quarter-1]
 First column of content
 [/column-quarter-1]
 [column-quarter-2]
 Second column of content
 [/column-quarter-2]
 [column-quarter-3]
 Third column of content
 [/column-quarter-3]
 [column-quarter-4]
 Fourth column of content
 [/column-quarter-4]
</code></pre>
If you want content to span multiple columns you can combine the shortcodes to create a column spans multiple spaces, for example:
<pre><code> 1 Third / 2 Thirds

 [column-third-1]
 First column of content
 [/column-third-1]
 [column-third-2-3]
 Second column of content that spans the second and third columns
 [/column-third-2-3]

 1 Quarter / 2 Quarters / 1 Quarter

 [column-quarter-1]
 First column of content
 [/column-quarter-1]
 [column-quarter-2-3]
 Second column of content that spans the second and third columns
 [/column-quarter-2-3]
 [column-quarter-4]
 Third column of content that occupies the fourth quarter column
 [/column-quarter-4]
</code></pre>
If you need to embed a set of columns within a column, you can do so by adding ‘inner-‘ to the shortcode as follows:
<pre><code> [column-half-1]
 Some Text
 [inner-column-half-1]
 Some more text
 [/inner-column-half-1]
 [inner-column-half-2]
 Even more text
 [/inner-column-half-2]
 [/column half 1]
 [column-half-2]
 The final text
 [/column-half-2]
</code></pre>
You can also change the background colour of a colour by adding an attribute to the shortcode as follows:
<pre><code> [column-half-1 background="e8e8e8"]
</code></pre>
