Nav pills dynamic layout issue - html

Question

I have 2 nav pill buttons that are supposed to change the layout when clicked. Both layouts include the sidebar which doesn't change.
Nav pill 1 changes the layout to:
sidebar | column 1 | column 2
Nav pill 2 changes the layout to:
sidebar | col 1 | column 2 | col 3
Right now what happens is that one column will show up next to the sidebar but the others will be under it and i'm not sure why this happens
#sidebar {
/* width: 250px; */
min-height: 100vh;
max-height: 100vh;
}
#sidebar_sub_header a {
border-radius: 0;
}
#sidebar_main_content::-webkit-scrollbar {
width: 0;
height: 0;
overflow-y: scroll;
scrollbar-width: none;
-ms-overflow-style: none;
overflow-x: hidden;
}
#sidebar_main_content img {
/* border: 1px solid white; */
border: 1px solid rgba(255, 255, 255, 0.1);
height:100px;
width:100px;
}
#sidebar_footer {
align-items: center;
text-align: center;
}
#main_body_channels {
height: 100vh;
}
#main_body_token_requirement_confirmation {
height: 100vh;
}
#main_body_roles {
height: 100vh;
}

Answer 1

For Bootstrap tabs to work every tab-pane needs to be wrapped in a tab-content container.
For your columns; add the class container-fluid to each tab-pane, then add a row that contains your columns. In my basic example all columns are equal in width, but its easily adjustable.
I am assuming you want a full-page layout, so in CSS do:
#sidebar,
main {
height: 100vh;
max-height: 100vh;
}
Then give each container-fluid in <main> the class h-100, which is equal to height: 100%.
Next, give each row the class h-100. Add flex class align-items-stretch to make each column stretch the full available height.
Note: This snippet is build upon my answer of your previous question, not upon the code in your question.
#sidebar,
main {
height: 100vh;
max-height: 100vh;
}
.tab-pane .row .col {
background: tomato;
}
.tab-pane .row .col:nth-child(2) {
background: lightyellow;
}
