Hi, i just send you email

Yes I've got it. I don't log to joomla. I suggest to check menu assigment in menu module. It looks that it is not turn on of all pages.

i check menu assignement for example in service section, and I assign menu to every category of this section, when i click on article the menu dissepear, it's not my first joomla but in this case I don't understand why the menu dissepear....

Thank I found thanks for your help!!!

Great

Post solution if you can it help others

in menu assignement you need to go on administration/module, choose you module menu "example leftmenu" and assign on mainmenu and choose the category where you want to see your menu appear but also need to assign your new menu.
for example you have your mainmenu, choose the category to assign and in second times you create before a "leftmenu" select also your category menu and when you click label on mainmenu or label in left menu your menu remain on every page/category you've selected before.

hope it's clear....
