Add Header Toggle Event

The code changes you are working with involve modifications to an Angular application's component files, specifically app.component.html and app.component.ts. These changes are related to the implementation of a side navigation toggle feature.

Overview

1. HTML Template (app.component.html):

   • The HTML template has been updated to include an event binding for a method called sideNavToggle(). This method is triggered by an event, likely a user interaction such as a button click, which is intended to toggle the visibility of a side navigation menu.

2. TypeScript Component (app.component.ts):

   • A new method, sideNavToggle(), has been added to the component's TypeScript file. This method is responsible for toggling the state of a boolean property, sideNavOpen, which presumably controls whether the side navigation is open or closed.

Why We Are Doing It

The purpose of these changes is to enhance the user interface by providing a dynamic and interactive side navigation menu. This is a common feature in web applications that allows users to access different sections of the application easily. By toggling the side navigation, users can expand or collapse the menu, optimizing screen space and improving the overall user experience.

How It Works

• Event Binding in HTML: The (sideNavToggle)="sideNavToggle()" syntax in the HTML file is an Angular event binding. It listens for a custom event, sideNavToggle, and calls the sideNavToggle() method in the component's TypeScript file when the event occurs.

• Toggle Logic in TypeScript: The sideNavToggle() method in the TypeScript file toggles the sideNavOpen property. This property likely determines the CSS class or style applied to the side navigation, controlling its visibility. When sideNavOpen is true, the side navigation is displayed; when false, it is hidden.

By implementing this toggle functionality, the application can provide a more interactive and responsive design, allowing users to control the visibility of the side navigation menu based on their needs. This approach is efficient and leverages Angular's powerful data binding and event handling capabilities.
