Mastering ng-select in Angular 12: Concatenating BindLabel

Angular is an incredible framework that simplifies building dynamic web applications. One of its powerful features is the ng-select component, which provides an intuitive dropdown experience. However, a common challenge developers face is how to effectively concatenate label fields — particularly when you want to merge first and last names into a single display value.

In this post, we'll walk through a problem involving the ng-select usage in Angular 12, particularly focusing on how to concatenate bindLabel by combining first_name and last_name of an employee. Let's dive right in!

The Problem

When using the ng-select component, a developer encounters an issue trying to display a combined label for employee names. The goal is to show the employee's full name while maintaining the unique id for each entry as the bind value. The initial implementation looked like this:

However, the result displayed nothing, despite the presence of data. This leaves us with the question: How can we effectively concatenate the bindLabel to display the full name?

The Solution

To achieve the desired outcome of displaying a full name in the dropdown, we will need to make some adjustments in the component’s TypeScript file. Let’s break it down into organized sections.

Step 1: Modify the TypeScript Logic

The key step involves mapping over the employees array to create a new property that combines the first_name and last_name. Here’s how to do it:

Explanation: In this code snippet, we're using the map function to iterate through each employee and add a new property, nameFull, which is a concatenation of first_name and last_name.

Step 2: Update the ng-select Usage

Now that we have a new field for the full name, we can modify our ng-select to utilize this newly created nameFull property for binding the label.

Here is the updated HTML code:

Explanation: We're now using bindLabel="nameFull" to inform ng-select to display the concatenated name we've created in the TypeScript code.

Final Thoughts

By following the steps outlined above, you've successfully resolved the issue of concatenating fields in the ng-select component of Angular 12. Not only have you improved the display of employee names in a user-friendly format, but you've also enhanced the overall UX of your application.

With Angular's flexibility, solutions like these create opportunities for better data presentation and improved user interaction. If you encounter similar scenarios in the future, remember this approach for combining data in your ng-select components!

Happy coding!
