Hi there!
Thanks for contacting us.
There is no default way to do that.
However, I can give you suggestion of using custom CSS. You can use the following custom code snippet in your custom CSS to achive that:
li.sp-menu-item.sp-has-child:hover .sp-dropdown {
visibility: visible !important;
}
body.ltr .sp-megamenu-parent .sp-dropdown {
display: block;
visibility: hidden;
transition: visibility 1s !important;
-moz-transition: visibility 1s !important;
-webkit-transition: visibility 1s !important;
}
Path towards custom CSS: Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
Note: Customization support is prohibited here.
Best Regards
