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):
enter image description here

I would like to widen the dropdown menu horizontally like in the next photo. 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 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. Failed attempts
