DropDown Hybrid menu question and wayfinder

Hi,
I’d like to create a dropdown menu with a dropline first sub menu which can be positioned to the left of the top level list item. Then, I’d like to have a dropdown sub menus for some of the main menu item and then once one selects an item from the dropdown, the dropline first sub menu would display as usual.
Is it something fairly easy to achieve using wayfinder? Any samples/pointers would be appreciated if anyone has anything...
Thanks for your help.
Eric

Have you peeked at the resources in the wiki and the samples that are distributed with Wayfinder?
