A Dynamic Field is a text element that intelligently updates automatically on your Book. For example, a page number field placed on the canvas will automatically show with the correct page number according to where you have placed this page within the overall Book Layout, without any need for manual editing by you. To update a Dynamic Field, follow the steps below:

Step 1: From within any page of your book, select the Elements tab from the menu on the left, followed by the Fields tab.

Step 2: You can see that all of the fields are populated with the details that correspond with that project (page numbers will update depending on which page they are placed). Select a field and drag onto the canvas.

Your chosen field will appear on the canvas.

Step 3: You can edit the style of the text from right on the canvas. If you want that text style to be saved as the default for any field you drag onto the canvas, be sure to click the Update button from the drop down at the top after editing.
