When you want to add an interactive asset in a chapter which would be available even in offline reading, you first locate your cursor where you want the interactive asset to appear in the text, and then click the Insert HTML5 icon in the editing toolbar.
A widow will open for you to add your file
Choose your previously downloaded file.
You have three options:
- Inline will let you add the assets right inside the text.
- Modal will place an icon and will only show to the reader when he or she clicks on the icon.
- Placeholder will only display an area which will be occupied in the final book.
