The Composite part enables you to build reusable pieces of a Web page made up of multiple Web Connection parts. Once you have built a composite, you can reuse it repeatedly on different pages, or even multiple times on the same page. A typical use for a composite would be to build a standard header or footer that you want to use on every page in order to provide a common appearance, or a common set of navigational links.
Building a composite is essentially the same as building a page. To create a new composite, follow these steps:
In order to use a composite in a page, select Add Part from the Options menu and specify the name of the part containing the composite. You can then place the composite on a Page just as you would any other Web Connection visual part.
