Converting HTML/CSS template in CMSMS :)

[uniqu3]

Replace {cms_module module="menumanager"} with {menu}
All default MenuManager templates use unordered list so that should work for you.

You can also import preinstalled Templates and adjust to your needs, save as new Template by clicking on "Import to Database" icon on the right.
Then your menu call would be {menu template='name-of-template'}.

For more information go to "Extensions -> Modules" in the table all installed modules are listed and on the right almost all modules have "Help" link, read that help for more information about possible Module Parameters and usage.
