Hello sreelalk,

Thank you for using SuperMagPro Theme.
Here are step guidelines for using that kind of mega menu.

• Create a Category
• Create SubCategory from the category, For eg if you have Sport main category, create football, volleyball, basketball, cricket subcategory
• Now insert posts in subcategories
• In the megamenu dropdown,select main category

	.both-sidebar #primary,

We think we finally understand your problem, This is because the post have many categories and you use that categories in the navigation. Please use following custom CSS

header-wrapper .menu > li.current-menu-parent a::before {
background: #fff;
}
.header-main-menu .acmethemes-nav ul li.current-menu-parent a {
background: #2D2D2D;
}

Thanks
