How to Hide/Show nav_panel Based on User Role: A Step-by-Step Guide

Are you tired of displaying the navigation panel to all users, regardless of their role? Do you want to customize the user experience based on their permissions? Look no further! In this comprehensive guide, we’ll show you how to hide/show the nav_panel based on user role, ensuring that only authorized users have access to specific features.

Understanding the Problem

Imagine a scenario where you’re building a web application with multiple user roles, each with different levels of access. You want to ensure that only administrators can see the navigation panel that contains sensitive features, while regular users only see a limited set of options. This is where conditional rendering based on user role comes into play.

The Solution: Conditional Rendering

Conditional rendering is a technique used to display or hide elements based on specific conditions. In our case, the condition is the user’s role. We’ll use a combination of HTML, CSS, and JavaScript to achieve this goal.

Step 1: Define User Roles

Before we dive into the code, let’s define the user roles and their corresponding permissions. For this example, we’ll use three roles:

Role	Permissions
Administrator	Full access to all features
Moderator	Access to moderate content
User	Limited access to features

Step 2: Create a Navigation Panel (nav_panel)

Create a basic navigation panel using HTML and CSS. We’ll keep it simple for demonstration purposes:

<nav id="nav_panel">
  <ul>
    <li><a href="#">Dashboard</a></li>
    <li><a href="#">Settings</a></li>
    <li><a href="#">Moderate Content</a></li>
  </ul>
</nav>

Step 3: Add User Role-Based Conditions

We’ll use JavaScript to add conditions based on the user’s role. We’ll assume that you have a `currentUser` object with a `role` property:

const currentUser = {
  role: 'Administrator' // Replace with the current user's role
};

Create a function to check the user’s role and return a boolean value indicating whether the nav_panel should be displayed:

function shouldShowNavPanel() {
  switch (currentUser.role) {
    case 'Administrator':
      return true;
    case 'Moderator':
      return false;
    default:
      return false;
  }
}

Step 4: Hide/Show the Navigation Panel

Use the `shouldShowNavPanel()` function to conditionally render the nav_panel. We’ll add a CSS class to hide the panel and then toggle it based on the user’s role:

<nav id="nav_panel" class="hide">
  <ul>
    <li><a href="#">Dashboard</a></li>
    <li><a href="#">Settings</a></li>
    <li><a href="#">Moderate Content</a></li>
  </ul>
</nav>

const navPanel = document.getElementById('nav_panel');

if (shouldShowNavPanel()) {
  navPanel.classList.remove('hide');
} else {
  navPanel.classList.add('hide');
}

Step 5: Add CSS for Hiding the Navigation Panel

Add a simple CSS rule to hide the nav_panel when the `hide` class is applied:

.hide {
  display: none;
}

Putting it All Together

Here’s the complete code:

<nav id="nav_panel" class="hide">
  <ul>
    <li><a href="#">Dashboard</a></li>
    <li><a href="#">Settings</a></li>
    <li><a href="#">Moderate Content</a></li>
  </ul>
</nav>

<script>
const currentUser = {
  role: 'Administrator' // Replace with the current user's role
};

function shouldShowNavPanel() {
  switch (currentUser.role) {
    case 'Administrator':
      return true;
    case 'Moderator':
      return false;
    default:
      return false;
  }
}

const navPanel = document.getElementById('nav_panel');

if (shouldShowNavPanel()) {
  navPanel.classList.remove('hide');
} else {
  navPanel.classList.add('hide');
}
</script>

<style>
.hide {
  display: none;
}
</style>
