that is possible with Visual Composer. In fact, it’s the way to get it.
When you are editing a row, there is the option to add an ‘ID’. Type the ‘ID’ you want and then, when you are creating the menu link, you have to use it in the url with a hashtag.
For example, in my demo website, I have the section #features. I attach you an image where you can check the ‘ID’ added.
And in your case, when you are creating the menu link, you have to added that anchor in this way: http://onsale.my/#features
