Page layout- Control the width of Narrow page ?

Hi:

We have several pages, with option 3, i.e., a narrow page

which is used for detailed navigation, and two wide/medium

pages for content. The narrow pane is occupying more than

required amount of width on the page.

Is there a way to specify the width of the narrow pane ?

In the page configuration, you may specify the height.

There is no box for width.

Any help is highly appreciated.

Thank you so much,

Prasad Nutalapati.
