Nav Bar Length

tgmad26,

This is a link the author put on another thread to about adjusting the width of a max menu:

https://www.maxmegamenu.com/documentation/faqs/adjust-sub-menu-width/

Another way is to put the max menu code within a div and set the width of the div.
For example if you want to add it to a specific area in your header, you could wrap it in a div such as:

<div class="header-search">
                 <?php wp_nav_menu( array( 'theme_location' => 'max_mega_menu_1' ) ); ?>
                 <?php get_search_form(); ?>
            </div>

Then set the width with css to:

.header-search {
    width: 65%;
}
