Modifying Layouts
You modify a layout by adding, modifying, or deleting content that is on that layout or by changing the layout (for example, reposition content on the layout). You can modify a personal layout.
You can also modify the following layouts by reserving them, which makes them a personal layout, making the changes, and requesting to publish:
- Layouts that are pending approval. 
- Layouts that have been rejected for publishing. 
- Layouts that have been shared. 
You must be in framework edit mode to modify a layout.
