How do you color fill part of a autoshape rectangle

[learning curve]

I see within the design formats they have autoshape rectangles with part of
it filled with color. There appears to be a dotted line, but no connectors.
The color seams to fill to this line. How do you accomplish this?

The dotted line means there is no line. If you turn off boundaries and guides in the
view menu, the dotted lines disappear. The rectangles are layered. Select the
rectangles and ungroup, click yes. You will see how it all is put together.
