Angular: Visibility Control: *ngIf vs. hidden

In Angular, managing element visibility often involves choosing between two options: *ngIf and the hidden property.

*ngIf:

• How it Works: Alters the DOM structure by adding and removing elements.
• Effect: When the condition is met, the element is in the DOM and available; otherwise, it's removed.

hidden Property:

• How it Works: Modifies CSS by changing the display property to 'none'.
• Effect: Keeps the element in the DOM but visually hides it.

Choosing the Right Option:

• *Use ngIf: If you want to completely remove an element from the DOM based on a condition.
• Use hidden Property: If you need to hide an element while keeping it in the DOM structure.

Conclusion:

*ngIf and hidden provide flexibility in managing element visibility in Angular. Choose based on your specific project requirements—whether you need to dynamically manipulate the DOM or subtly hide elements.
