Here we will focus on how to customize the FCKeditor of dnn. Before that, we will briefly describe the directory structure of FCKeditor in dnn. Currently, FCKeditor appears in dnn as an htmleditorproviders, that is, dnn has integrated FCKeditor and provided a default providersl for management. In the future, it will be convenient to replace other providers.

If you open these two directories, you will be clear, in fact, the FCKeditor directory contains all the default FCKeditor items, such as skins, plugins, and Lang (Language Pack). Custom is some of the modifications that dnn has customized for the default FCKeditor. for example, the default dnn editor toolbar attribute is added:
