Header menu wraps

Hi there,

I'm using max mega menu plugin in my header. The menu wraps, when the browser window is made too small on my desktop. I asked the plugin developer for css to ensure the menu does not wrap. His CSS is below. It does not work, leading me to believe it may be a GP container that needs similar CSS? Thanks for any suggestions!

/* Minimum width of desktop menu */
#{$wrap} #{$menu} {
min-width: 1050px;
display: block;
}
