In a navbar how can I extend the dropdown menu horizontally across the width of the page container?
Currently, when I hover over an item in the navbar, a horizontal drop-down menu opens like this (note the width of the drop-down menu):
What would I like to achieve?
I would like to widen the dropdown menu horizontally like in the next photo, but only desktop version. I would like the dropdown menu to be as wide as the container (the one that Bootstrap already uses with the container class) that I am already using in my navbar and that I will also use throughout the body of the site.
In the photo (photomontage/collage) I am inspecting the navbar with Chrome so as to highlight the navbar container to give you an idea of how wide I would like the dropdown menu to be.
Can you help me and show me how to get it? I have tried several attempts, but I failed.

Add the Bootstrap class position-relative to the container and position-static to the dropdown.
Add the class w-100 to the dropdown-menu.
Finally the vertical view for the mobile version:
