I have understood how to place the sub level, but how to initialize the place of my menu [first buton](if i have 3 menu on the same page)
Tigra Menu is positioned absolutely. In menu_tpl.js specify in pixels vertical offset from the top of the document and horizontal offset from the left
Tigra Menu PRO has additional alignment features.
More information can be found in product documentation.
Can you center you horizontal menu ?
I can about guess it by entering a digit, but that's for my 800-600 res. when you look at it with a higher resolution it's way of center
