Material Design Autocomplete search feature in Angular 2

I'm encountering some challenges with autocomplete in Angular2 Material Design. Here are the issues I'm facing:

1. When I type a character that matches what I'm searching for, it doesn't display in the autocomplete dropdown as shown in the images below:

  1. Before typing in the search box.
  2. After typing in the search box.

2. Another problem is that when I select an item from the user list, it shows [object Object] and I'm not sure why. See the images below:

  1. Before selecting an employee from the list.
  2. After selecting an employee from the list.

Please review my code below to see if there's anything I've missed:

Angular Code: new-useraccount-components.ts 

// Angular code goes here

AppModule: app.module.ts

// AppModule code goes here

As a beginner exploring this new framework, I would appreciate any guidance on resolving these issues. Thank you and have a great day!

Answer №1

If you take a closer look at the documentation, you will find clear instructions:

One important section to pay attention to is "Setting separate control and display values". The reason your search result is not displaying correctly may be because you are trying to show something different from what you have specified in the [value].

Another issue you may encounter is that when you select an item from the list, the actual value of that item gets inserted into the search box. Given that this is a userAccount, instead of the username, it might display as [object Object].

By simply changing to [value]="userAccount.username", you might be able to resolve both issues. If that doesn't work as expected, refer to the documentation's explanation on using the [displayWith] attribute for further guidance.
