Hello, David,
Thank you for contacting us and for using XStore.
We did not test such a menu structure before, in your case, the next custom CSS code can be used:
.elementor-widget-wp-widget-etheme-menu .menu-item-has-children>a>.arrow {
display: none;
}
.header-wrapper .menu-element .menu .menu-item-has-children .nav-sublist-dropdown {
width: 18em;
left: 100%;
top: -100%;
}
.item-design-mega-menu.columns-2 .nav-sublist-dropdown .container>ul>li {
width: 100%;
margin-bottom: 0;
padding: 0px 0.6em 1.4em 0.6em;
border: none !important;
}
