It is important to understand how to navigate around the chapters of your ebook and do all kinds of manipulations such as re-arranging them, etc. Kotobee Author supports chapters and subchapters, as part of the EPUB 3 specifications. Initially upon starting a new book, at the left area of the screen you will find a blank chapter created for you, named Untitled Chapter. You can change the name of the chapter directly from this textfield.

Creating chapters

  • To create a new chapter, click on the New chapter button.

  • You will be asked what kind of layout you would want to apply to this chapter: reflowable or fixed layout. For more information about these layout modes, please refer to this knowledge-base article. You may set a default layout mode when creating chapters (by checking Don't ask again), to prevent the dialog from showing every time. If you later on decide to change the layout mode, you may click on the button with the three dots next to the New chapter button.

  • The chapter title box will be automatically highlighted to let you start typing the chapter title. If you leave this blank, it will automatically be named Untitled Chapter.
  • Clicking the + button residing next to the chapter title, will allow you to create subchapters within that chapter. It is possible to continue adding as many subchapters as you want. You can easily add a title to your subchapter using the same method above.

Creating chapter guides

Any of your root chapters or subchapters can act as a chapter guide. A chapter guide is basically a table of contents with links to all its child chapters. To create this guide, decide which chapter or subchapter you want to use then click on the Create chapter guide button next to it. Please note that if you choose Yes, this will overwrite all the chapter’s content.

Deleting and rearranging chapters

The bottom area of the chapter management panel has some options for chapter arrangement and deletion. 

  • The red Delete button with a trash can icon, will delete the currently selected chapter.

  • The adjacent Arrange buttons, with up and down arrow icons, will shift your chapter upwards and downwards in its current list.

  • The dropdown list at the left, allows you to control the nesting level of the selected chapter. You may choose it to be a subchapter of any existing chapter in your book.

Previewing a chapter

When creating content in a chapter, and adding especially interactive elements, you may not immediately see the end result of this type of content. In edit mode, a placeholder is used to mark the locations of videos, galleries, widgets, etc. To have an actual realistic preview of the chapter, simply click on Preview Mode on the bottom right side of your screen. Note that this step will only preview the selected chapter. For a preview of the whole book, refer to the Customize section.

Managing chapter visibility


You an choose to remove a chapter form the table of contents, while keeping it included within the normal navigation of the ebook (for users who navigate using the Next and Previous buttons). To exclude a chapter from the table of contents, simply uncheck the Include in TOC property just beneath the content area. Chapters that are not included in the table of contents will still exist in the chapters menu on the left while you're editing, but in a dimmed color.


In some cases, you may want to hide a chapter entirely, and make it invisible from normal navigation in the ebook. The only way to display such a chapter would be through a hyperlink from another chapter. To mark a chapter invisible, check the invisible property just beneath the content area. Invisible chapters will still appear in the chapters panel but will have a strike-through style.

Advanced editing


You may edit the chapter in source mode (HTML) to give you accurate precision over your editing, and allow you to add custom code. This is done using the Source Mode button at the bottom right. To see the HTML file inside the EPUB's archive, click on Show in File Manager to open the chapter's file in the File Manager.
