Implement a vertical scrollbar within the Bootstrap navbar to accommodate a large number of items

I implemented a sidebar using Bootstrap within a React application. Below is the code snippet:

import React from 'react';
import './style_sidebar.css';

export default class Sidebar2 extends React.Component {
    render() {
        return (
            <div>
                <ul className="nav flex-column sidebar bg-dark">
                    <h3 className="text-warning mt-3 ml-2">Bootstrap Sidebar</h3>
                    <i className="fa fa-user-circle text-white mt-3 ml-5 pl-4 icon-user" style={{'fontSize': '5em'}}></i>
                    <h4 className="text-warning ml-3 mt-5">Components</h4>
                    <li className="nav-item">
                        <a className="nav-link text-light" href="#a"><i className="fa fa-table fa-lg"></i> Table<hr className="bg-warning" /></a>
                    </li>
                    <li className="nav-item">
                        <a className="nav-link text-light" href="#b"><i className="fa fa-bar-chart fa-lg"></i> Chart<hr className="bg-warning" /></a>
                    </li>

                    ...

                </ul>
            </div>
        );
    }
}

The CSS part for the sidebar:

.sidebar {
    width: max-content;
    height: 100vh;
    padding: 10px;
    position: fixed;
    z-index: -1;
}

.user-icon {
    border: 1px solid;
    border-radius: 40px;
}

@media only screen and (max-width: 600px) {
    .sidebar {
        width: 100%;
        height: max-content;
    }

    h3 {
        align-self: center;
    }  

    .icon-user {
        align-self: center;
        margin-right: 100px;
    }
  }

When adding more items to ul, they appear at the top of the page instead of creating a vertical scrollbar. Trying to add overflow-y: scroll resulted in a horizontal scrollbar. Any suggestions on how to fix this?

Struggling to make the sidebar responsive, even with media queries. How can I achieve responsiveness given my limited experience with bootstrap?

Additionally, looking to implement a toggle button for the sidebar that collapses when the screen size is small. Seeking advice on how to accomplish this using the latest version of Bootstrap.

Answer №1

To address the problem of scrolling, utilize the flex-wrap property like so:

.sidebar {
width: max-content;
height: 100vh;
padding: 10px;
position: fixed;
z-index: -1;
-ms-flex-wrap: nowrap;
flex-wrap: nowrap;
overflow-y: auto;

}

To ensure responsiveness, hide the sidebar initially and reveal it upon clicking the toggle button.
