# CKEditor Sample — Using the Stylesheet Parser Plugin

This sample shows how to configure CKEditor instances to use the Stylesheet Parser (`stylesheetparser`) plugin that fills the Styles combo based on the CSS rules available in the document stylesheet.

To add a CKEditor instance using the stylesheetparser plugin, insert the following JavaScript call into your code:

    CKEDITOR.replace( 'textarea_id',
    	{
    		extraPlugins : 'stylesheetparser'
    	});

Note that `textarea_id` in the code above is the `id` attribute of the `<textarea>` element to be replaced with CKEditor.
