I'm currently working with Bootstrap 4 and attempting to make 3 columns on the page fill 100% height, only displaying scrollbars within the columns and not on the entire page. I have experimented with applying h-100 to the row div, as well as implementing custom CSS changes such as setting the height and max-height to 100% on each column. Despite trying various solutions from Stack Overflow and other sources, I can't seem to get it to work properly. I would greatly appreciate any assistance. Here is the website:

Then, click on the first button on the left (labeled "18 Classes"). You will notice that the middle column contains a list group that populates with items.
