Menu with relative position

hello,

I need to set my coolmenu4 with a relative position. It is an horizontal menu like this

--------------------+------------------------+---------------------------+---------------------+
|     menu1     |       menu2         |          menu3        |       menu4      |
--------------------+------------------------+---------------------------+---------------------+

I have tried to chande the position from "absolute" to "relative" but I have now the following menu

--------------------+
|     menu1     |
--------------------+
                    +--------------------+
                     |     menu2      |
                    +--------------------+
                                          +--------------------+
                                           |     menu3      |
                                          +--------------------+
                                                                +--------------------+
                                                                 |     menu4      |
                                                                +--------------------+

I think that what is happening is that relative position is applyied to all menu items instead of the general menu...
how to have my menu in line with relative position?


Thanks for your help
