ListLevel property controls the level at which the paragraph appears in the bulleted or numbered list. The values are 0-based where the left-most level is 0 level. To control the appearance and formatting of the bullets or numbers, set the associated (association is made via the ListId property) RichTextList's ListStyleId to refer to a ListStyle in the root node's DocumentRootNode.Styles collection that provides bullets and/or numbers with desired formats. You can either create a custom ListStyle or use one of the built-in styles exposed via the AvailableStyles. If you do use on the the built-in style id's, make sure to add the built-in ListStyle to the root node's Styles collection.
