There are two ways to create a frameset in Dreamweaver: You can select from several predefined framesets or you can design it yourself.
Choosing a predefined frameset sets up all the framesets and frames needed to create the layout and is the easiest way to create a frames-based layout quickly. You can insert a predefined frameset only in the Document window’s Design view.
You can also design your own frameset in Dreamweaver by adding “splitters” to the Document window.
Before
creating a frameset or working with frames, make the frame borders visible
in the Document window’s Design view by selecting View >Visual
Aids > Frame Borders.
Create a predefined frameset and display an existing document in a frame
Create an empty predefined frameset
Create a frameset
Select Modify > Frameset,
then select a splitting item (such as Split Frame Left or Split
Frame Right) from the submenu.
Dreamweaver splits the window into frames. If you had an existing document open, it appears in one of the frames.
Split a frame into smaller frames
To split the frame where
the insertion point is, select a splitting item from the Modify >
Frameset submenu.To split a frame or set of frames vertically or horizontally, drag a frame border from the edge into the middle of the Design view.
To split a frame using a frame border that isn’t at the edge of the Design view, Alt‑drag (Windows) or Option-drag (Macintosh) a frame border.
To divide a frame into four frames, drag a frame border from one of the corners of the Design view into the middle of a frame.
To create three frames, start
with two frames, then split one of them. It’s not easy to merge
two adjacent frames without editing the frameset code, so changing
four frames into three frames is harder than changing two frames
into three frames.
Delete a frame
Drag
a frame border off the page or to a border of the parent frame.
If there’s unsaved content in a document in a frame that’s being removed, Dreamweaver prompts you to save the document.
