How to make such a menu (adaptive)?

Question

css

Good day. Please advise how to implement such a menu? But the most important thing is how to vertically stretch the blocks to full width? The whole project goes to BS3.

Answer 1

Don't forget to grab the plugin https://github.com/kamens/jQuery-menu-aim
and the main menu can start with
#sideMenu {
position: fixed;
width: 190px
height: 100%;
......
If you need at all for the entire height, then just pos: abs; h:100% in body
if to viewport height then js -> window.height -> inline style

Answer 2

width=100%
