Columnizer is a jQuery based WordPress plugin that formats your content into columns. All you need to do is embrace your content in a single set of shortcodes denoting the number of columns you’d like. Like this:
<pre><code>[threecolumns]
Lorem ipsum...vitae nunc.
Curabitur fringilla...consectetur arcu.
Proin id...pretium eros.
etc...
[/threecolumns]
</code></pre>
The rest is taken care of for you. Just write out the number of columns (up to twelve) followed by the word ‘columns’ with no space (as above) and your column formatting needs will be satisfied most splendidly. Other column plugins need you to divvy up the content between sets of tags. Columnizer does it for you!
To customize the margins between columns edit columnizer.css. Alternatively you could override the rules in your own css file by adding an extra level of hierarchy. Something like this:
<pre><code>#main #columnizer .first div {
 margin-right: 8px; /*changed spacing to 8px*/
 margin-left: 0 !important;
}
#main #columnizer .last div {
 margin-left: 8px; /*changed spacing to 8px*/
 margin-right: 0 !important;
}
#main #columnizer .column div {
 margin-left: 8px; /*changed spacing to 8px*/
 margin-right: 8px; /*changed spacing to 8px*/
 border-left: 1px solid grey; /*new rule to add slick dividers*/
 border-right: 1px solid grey; /*new rule to add slick dividers*/
}
</code></pre>
WP Columnizer is based on the jQuery plugin “Columnizer” by Adam Wulf.

As easy as it gets. Add column classes to widgets with a select box, check whether the widget is the first, and save!
I’ve built this plugin for the Genesis Framework, though it will work with any theme that uses the (old) Bootstrap column classes.
You can also add your own classes through various filters to use this plugin with your theme’s grid framework.
<h4>Compatibility (IMPORTANT!)</h4>
This plugin does NOT add CSS for these columns. It ONLY adds the column classes to your widgets. The actual CSS should be added in your theme.
<h4>Filter: `genesis_widget_column_classes`</h4>
Allows you to change the available column classes
Parameters: <code>array</code> Default column classes. 
Return: <code>array</code> Array of column classes.
<h4>Filter: `genesis_widget_column_classes_capability`</h4>
Change the capability required to modify column classes. 
Since 1.2.2
Default: <code>edit_theme_options</code> 
Parameters: <code>string</code> The default capability. 
Return: <code>string</code> The new capability.
<h4>Filter `genesis_widget_column_classes_select_multiple`</h4>
Allow multiple classes to be selected. 
Since 1.3 
Return: boolean.
You can use these filters inside your theme functions.php file or in a plugin.
