mobile menu sub menu open by default

Hello,

This is possible using CSS but not super ideal. Consider trying this HTML:

<ul class="sub-menu-container mobile-submenu-open">

and then this CSS:

@media (max-width: 575.98px) {
	.mobile-submenu-open {
		display: block !important;
	}
}

You adjust the values according to your needs.

Hope this Helps!
