Hi there!
Thanks for contacting us.
Are you talking about the right part of the first level dropdown as shown in the following screenshot?
https://prnt.sc/1sz9tvb
Then you can use the following code in your custom CSS:
body.ltr .sp-megamenu-parent .sp-dropdown.sp-dropdown-main.sp-menu-left {
left: -110px !important;
}
Hope this helps anyways!
Note: 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.
Best Regards
