How to insert Vertical, Accordion Navigation Bar (NOT slider)?

[Acorn]

For some reason I didn't get a notification that there were replies like before. Thank you all for replying.

Acorn, will I need to worry about the images that are associated with the CSS accordion menu? So, I put the CSS in the head section of the placeholder and the html in the body? (It has both.)

A bit more tricky than that.
Each of the menu images has to be "seen" by your Xara design page. That is, they need to put placed on the page, Named and hidden behind something.
You then will have a number of URL to the images, similar to index_htm_files.<image-name>.png.
In your Placeholder body (code) you insert these links to replace the current paths.
