- Click your page in the Hierarchy List
- In the Object Properties, change to Flowed - SEE NOTE AT BOTTOM
- Change your textfield properties to Allow Multiple Lines and Expand to Fit.
- Objects below the expanding field will move down and over to another page if it reaches the bottom.
NOTE: When you change your page to Flowed, all your positioned objects will move to a hierarchal order down the page. My best tip is to build your flowed page using multiple tables with different rows and columns to 'position' objects where you want. There is no reason why you can't use a single row / column table if you need to for positioning.
