Hi andrzej,

Thanks for your patience.

Please remove previous code and use below one in order to show the dropdowns immediately after hovering before the calculation of all offsets has taken place. But, please note that in this case, horizontal shifts of the dropdowns can be visible, which cannot be resolved otherwise.

.wd-nav-main:not(.wd-offsets-calculated) .wd-event-hover:hover > .wd-dropdown, 
.wd-nav-main:not(.wd-offsets-calculated) .wd-event-click.wd-opened>.wd-dropdown, 
.wd-nav-main:not(.wd-offsets-calculated) .wd-dropdown.wd-opened {
	pointer-events: visible;
    pointer-events: unset;
    opacity: 1;
}

Regards,
