MaxiMenu CK Level 1 Stretch

Good Afternoon!

I am using the MaxiMenu CK 8.2.3 on Joomla 3.6.5. I would like for the Level 1 menu items to stretch clear across the screen but I can't seem to find the setting for that. Thank you very much for any help!

Hi
you can use margins in % to have a similar behavior
Else you shall use some custom css rules to manage the width of the elements in %, but take care about the responsive.
There is no width option for the element in the module because it is something really hard to manage in responsive without custom rules
