Hi, how can i make the submenu to have full width?
Full width i mean the width to be same to the main menu's width.

Hi
you must give the margin-left as negative value and the width on div.floatck in the CSS, or use the params if you have the plugin params.

I have the plugin params. How can i fix it with that?

when editing the parent item "active menu" you have the tabs "maximenu params" in the options, then you can give the submenu width, and the horizontal offset

I dont understand what is the ' parent item "active menu" '.
Is it a menu item or a module?

I have purchased Vm and params plugin if that helps.
Documentation does not provide the info i'm asking so i am really gratefull for your help.
If asked, i can give you login data to fix even one menu for me.

I look at your image, and the hover item is called "active menu"
this is the parent link where the submenu is located. Edit this link.
In any link you will see the params, and you can find this information in the plugin documentation
