Boot box 4 with collapsible side panel

Question

I want to create a collapsible sidebar that the user can switch. After long games I achieved this, but right now, it is very ugly . Here is the code:

<div class="container-fluid">
  <div class="row">
    <nav class="col-md-3 collapse show" id="sidebar">
      <h2>I'm a sidebar</h2>      
    </nav>
    <main class="col-md-9">
      <i class="fa fa-times" data-toggle="collapse" data-target="#sidebar" aria-hidden="true" aria-expanded="false" aria-controls="sidebar"></i>
      <h2>I'm the main content</h2>
    </main>
  </div>
</div>

The problem with this is that the collapse is vertical, and then collapses, the content does not go full width!

There is an easy way, you do not need to use jQuery. Take a look at this example:

<div class="container-fluid">
  <div class="row">
    <nav class="col-md-3 collapse show" id="sidebar">
      <h2>I'm a sidebar</h2>      
    </nav>
    <main class="col-md-9">
      <i class="fa fa-times" data-toggle="collapse" data-target="sidebar" aria-hidden="true" aria-expanded="false" aria-controls="sidebar" onclick="document.getElementById(this.getAttribute('data-target')).style.display = 'none';"></i>
      <h2>I'm the main content</h2>
    </main>
  </div>
</div>

I changed data-targetand added a very simple one onclick.

EDIT:

Further improvements:

<div class="container-fluid">
  <div class="row d-flex">
    <nav class="col-md-3 collapse show width" id="sidebar">
      <h2>I'm a sidebar</h2>      
    </nav>
    <main class="col-md-9">
      <i class="fa fa-times" data-toggle="collapse" data-target="#sidebar" aria-hidden="true" aria-expanded="false" aria-controls="sidebar" onclick="var that = this; setTimeout(function() {console.log(that.parentNode);that.parentNode.style.flex = 'auto';that.parentNode.style['max-width'] = 'none';}, 2000);"></i>
      <h2>I'm the main content</h2>
    </main>
  </div>
</div>
