New content place holders can only be added to a layout. Layouts typically are designed by a professional designers. Blackbaud can create a new layout and new content place holders on your behalf, though this is typically a billable service.
If you are familiar with html and CSS, you may be able to configure the content place holders via:
- Navigate to Site Explorer>Layouts
- Edit the desired layout
- Navigate to Insert>Content Placeholder
- Enter a content placeholder ID, and optional description
- Click Insert
Alternatively, multiple parts may be added to the same content place holder.
