Dynamically Displaying Items in Rows Using Angular ngFor

Are you faced with the task of displaying an array of items in rows, with a fixed number of items per row? If so, this guide is perfect for you! Today, we’ll explore how to achieve this seamlessly using Angular’s ngFor directive along with CSS grid and flexbox layouts. Let’s dive into the problem and then explore various solutions to implement it effectively.

The Problem: Displaying Items in Rows

You might have an array with a varying number of elements, and your goal is to display these elements in a structured way—specifically, five elements per row. For example:

Examples of Desired Output

If your array has seven elements:

If your array has fifteen elements:

The main challenge is to dynamically render your items in such a way that the layout remains intact regardless of the array size.

The Solution: Using CSS Grid or Flexbox

You can successfully implement this behavior using either CSS grid or flexbox. Let’s break down each approach.

1. Using CSS Grid

The grid approach allows you to create a structured layout with fixed columns. Below are the steps to implement it:

CSS for Grid Layout

Here's the CSS needed to set up a grid that displays five elements per row:

HTML Structure

Using ngFor, your HTML might look something like this:

This setup will ensure that your array elements are displayed in rows of five.

2. Using Flexbox

Alternatively, you can achieve the same result using a flexbox layout, which adds more flexibility, especially for responsive designs.

CSS for Flexbox Layout

Here’s how the CSS for the flex approach would look:

HTML Structure

The HTML would again utilize ngFor but in a flex structure:

Using the flex layout allows you to easily manage responsiveness. You can utilize properties like flex-wrap and set min-width to adapt your layout on smaller screens.

Conclusion

Both the grid and flex approaches are valid ways to dynamically display items in rows using Angular's ngFor. Your choice between the two may depend on your specific requirements, such as responsiveness or complexity of design.

CSS Grid allows for greater control over the positioning of elements and is ideal for layouts with a defined number of areas.

Flexbox provides flexibility, making it easier to adapt to different screen sizes, making it a preferred choice for responsive designs.

No matter which method you choose, you can easily control the layout of your elements in a visually appealing manner. Happy coding!
