I am currently utilizing a navigation bar from a Bootstrap theme within my React project.
The navigation bar includes an in-built media query that determines whether it should display as a dropdown menu or not, with a toggler to handle the dropdown functionality:
<button class="navbar-toggler collapsed" type="button" onClick={this.onToggleNav} data-toggle="collapse" data-target="#navbarColor01" aria-controls="navbarColor01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
I then conditionally render the content of the navbar based on the state:
<div className={this.state.navClosed ? "navbar-collapse " : "navbar-collapse collapse"} id="navbarColor01" >
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="text" placeholder="Search" />
<button class="btn btn-secondary my-2 my-sm-0" type="submit">Search</button>
</form>
In my current setup, I encounter an issue where the navbar items are only visible when the navClosed state is set to true. If it's false, the content will be hidden unless the screen width is reduced and the toggle button appears.
Is there a way to implement a lifecycle hook or conditional handler to automatically adjust the state based on the screen width reaching a certain breakpoint?
state = {
navClosed: false,
