# How Do I: Use the Same Header and Footer for All Desktops?

Using the WebLogic Administration Portal, portal administrators ultimately determine which header/footer combination is used for a portal desktop.

Desktop headers and footers are defined by shells. Each shell can reference a JSP or HTML file for displaying content. For example, you can create a campaign with WebLogic Workshop Platform Edition that displays targeted content to users. Then you can reference the campaign in a shell's header. When a user accesses the desktop they see the results of the campaign in the header.

As a portal developer, you can create shells and select a default shell for a desktop.

To select a default shell for a desktop

1. With your portal file open in the WebLogic Workshop Platform Edition Portal Designer, select the Desktop icon in the Document Structure window.
2. In the Property Editor window, use the Shell field to select the shell containing the default header/footer you want the desktop.
3. Save the portal file.
4. To use the same shell for other desktops, repeat these steps for each portal file.

## Samples

To view examples of fully functional portals, see the Portal Samples.

Also, when you create a Portal Web Project, a predefined set of shells is added to your project in the <project>\framework\markup\shell directory.
