• If appears next to the page parameter, this means that the page parameter is inherited from the page template on which the page is based. To edit, delete, or move a page parameter that is inherited from a page template, you must edit, delete, or move the parameter in the template itself.

• The default value can contain up to 4000 characters.
• This field is available only for Standard and Mobile pages and pages of custom types that are based on the Standard page type.

Select to allow users to change the value of the parameter when they customize the page.

Example: If you add a page parameter to store the value of a stock symbol, you will probably want to enable users to change the value of the parameter to the stock symbol of the company for which they want to see stock information.

Note: This field is available only for Standard and Mobile pages and pages of custom types that are based on the Standard page type.

Enter a description for the parameter.

If you allow users to customize the value of this page parameter (by selecting the Customizable check box), the description appears on the Customize Page: Parameters tab. Use the description to provide users with hints or an example of what kind of value to provide for the parameter.

Lists the portlets on the page and indicates whether they have portlet parameters associated with them. Click or the portlet name to expand the portlet and display its parameters. If a portlet does not have any parameters defined, it cannot be expanded in the list.

Notes:

• Click Expand All to display the parameters for all the portlets on this page.
• Click Collapse All to hide the parameters for all the portlets on this page.
• For information about how to add parameters to your portlets, see the Portal Developers Kit on Oracle Technology Network.

Choose:

• Null if you do not want to provide a value for the portlet parameter
• Page Parameter if you want to use the value of one of the page parameters for the portlet parameter
• System Variable if you want to use the value of a system variable for the portlet parameter, for example USER_NAME
• Constant if you want to provide a specific value for the portlet parameter

If you are using Internet Explorer: Choose the page parameter or system variable that provides the portlet parameter's value, or enter the constant value for the portlet parameter.

If you are using Netscape Navigator: Enter the name of the page parameter or system variable that provides the portlet parameter's value, or enter a value for the portlet parameter. If you are not sure of the page parameter or system variable name, click and select a parameter or variable from the list provided.

Example: Say there is a stock ticker portlet on the page that uses the value of one of its parameters to determine the company for which to display stock information. You can specify that the portlet parameter obtains its value from your page's stock symbol parameter. As the page designer, you can set the value of the page parameter so that your page shows the stock information of a particular company. In addition, you can allow your users to change the value of the page parameter (by selecting the Customizable check box for the page parameter), so that they can choose for themselves what information they want to see in the stock ticker portlet.
