megamenu relative / default

i have an issue with the mega menu

on links towards the right, the menu makes the page bigger than it needs to be and pops off screen

example:

https://drive.google.com/file/d/1fFamxRtys1a-7pot1ZSJJrwDcRpToiqR/view?usp=drive_link

this is with relative, if i try default – the menu pops in the middle, and you cannot navigate to it (as its too far away)

is there a way to get past this, ie have some pop relative to the menu, to the right (for left menu items) and pop relative to the left for right menu items
