You can edit your page anytime. You can change the name and description of the page, as well as redefine the subpage and contents for the page. You can reorder the sequence of the display of the subpages or components in the contents by changing their Sequence level in their numerical order. And you can restrict the subpages from being viewed by everyone by choosing an Availability level that allows only certain privileged users to view some of the subpages. The levels are:
You can copy a subpage that allows you to create a replica of the original and then edit it to suit your requirements. You can also remove a subpage or a component from the contents anytime during the edit process.
You can edit your subpage anytime. You can change the name and description and the icon of the subpage, as well as redefine the contents for the freeform page. You can reorder the sequence of the display of the components in the contents of the subpage by changing their Sequence level in their numerical order.
And you can restrict the components from being viewed by everyone by choosing an Availability level that allows only certain privileged users to view some of the subpages. The levels are:
You can copy a component that allows you to create a replica of the original and then edit it to suit your requirements. You can also remove a component anytime during the edit process.
Note: You can set up the pages in your project home page or any top-level page to hold content directly under the page, or use the page as a container to hold subpages. If you add a component or freeform page to a page, you will no longer be able to add subpages to that page until these are removed. If you add a subpage to a page, you will no longer be able to add components or freeform pages, until all subpages are removed. However, you can override this behavior by adding components, subpages, and freeform pages directly to the Subversion repository of your project. When you do that, all the elements entered will be accessible from the project home page.
Note: If you delete the "Documents" component from a page, subpage or freeform page of a project, two directories namely "templates" and "documents" will get deleted from the respective path of that project's Subversion repository. If you add the "Documents" component to a page, subpage or freeform page of a project, the "templates" and "documents" will be created in the respective path of that project's Subversion repository. For example, if you delete the "Documents" component from the "Definition" subpage of the "Stages" page, the "documents" and "templates" directory will be deleted from this path of the project's Subversion repository: https://[project name].[domain name]/source/browse/[project name]/trunk/www/alm-process/1-Stages/1-Definition/
But, if you try to manually add or delete the two directories ("templates" and "documents") to or from the project's Subversion repository without making the necessary changes in the page.xml file, the changes may not get reflected in the project's home page.
Note:You may make changes to your project home page while customizing it using the "Edit" link. You may also make changes directly in the Subversion repository by adding pages or subpages or by including other changes to the content. These changes may not be reflected immediately in the screen. It may take a few minutes before you see them.
