There are four frameset views in the Frameset editor: Frames, Source, Preview, and No Frames. You can make modifications to the frames or frameset in the Frames, Source, and No Frames views. No Frames view displays the page as seen with a Web browser that does not support frames.
Frames view displays the frames you have defined and the contents of the pages. Frames view lets you drag and drop Web pages from your Web target to frame panes in your frameset. You can also modify the size of the frames by stretching the frame panes. Data cannot be placed directly in the frame panes.
Source view lets you edit in the source file. As with Source view in the rest of the Web target environment, Source view provides the most flexible editing environment. In Source view you can drag and drop items from the component or language tab in the System Tree area.
Preview is a display-only view. It shows what the page would look like when viewed with a Frame-enabled Web browser.
The No Frames view displays the page as it is seen with a Web browser that does not support frames. No Frames view lets you add text to the page that is not seen when you switch back to the Frames view.
