AutoGrow Plugin — CKEditor Sample

# CKEditor Samples » Using AutoGrow Plugin

This sample is not maintained anymore. Check out its brand new version in CKEditor Examples.

This sample shows how to configure CKEditor instances to use the AutoGrow (`autogrow`) plugin that lets the editor window expand and shrink depending on the amount and size of content entered in the editing area.

In its default implementation the AutoGrow feature can expand the CKEditor window infinitely in order to avoid introducing scrollbars to the editing area.

It is also possible to set a maximum height for the editor window. Once CKEditor editing area reaches the value in pixels specified in the `autoGrow_maxHeight` configuration setting, scrollbars will be added and the editor window will no longer expand.

To add a CKEditor instance using the `autogrow` plugin and its `autoGrow_maxHeight` attribute, insert the following JavaScript call to your code:

    CKEDITOR.replace( 'textarea_id', {
    	extraPlugins: 'autogrow',
    	autoGrow_maxHeight: 800,

    	// Remove the Resize plugin as it does not make sense to use it in conjunction with the AutoGrow plugin.
    	removePlugins: 'resize'
    });

Note that `textarea_id` in the code above is the `id` attribute of the `<textarea>` element to be replaced with CKEditor. The maximum height should be given in pixels.
