I'm currently evaluating DHTML Menu (for buying purposes)

First of all: this is the best DHTML Menu tool I've seen, I've evaluated 4 different products (including yours) and I'm just impressed by the ease of use of your tool.
I want the menu bar (horizontal) to be part of my page (yes I've read the FAQ and I use position="relative" for my main menu).
Now, I'd like the menu to enpand itself to 100% of the page width with the menu options at the left (as it is currently).
How can I do that ?
Thanks.
Hervé.
