IndentClasses

FCKeditor allows the use of CSS classes for block indentation. The class should be defined in the EditorAreaCSS file:

.Indent1
{
margin-left: 40px;
}

.Indent2
{
margin-left: 80px;
}

.Indent3
{
margin-left: 120px;
}

We apply the class to the IndentClass option:

FCKConfig.IndentClasses = [ 'Indent1', 'Indent2', 'Indent3' ] ;

NOTE: If you use this option the settings of IndentLength and the IndentUnit will be override.
