Utilize ngx-select-dropdown to showcase various displayKey values at once

I am currently utilizing the ngx-select-dropdown plugin with a search feature, and I am looking to specify multiple values for the displayKey property such as: firstname and lastname.

Here is the configuration object I am using:

dropdownconfig = {
    displayKey: 'firstName, lastName',
    search: true,
    placeholder: 'Select User',
    height: '150px'
};

html:

<ngx-select-dropdown (change)="selecteAdmin($event)" [config]="dropdownconfig" [options]="allUserData" [(ngModel)]="singleSelect" [multiple]="false"></ngx-select-dropdown>

Is there a way to specify multiple values for the displayKey? Additionally, any suggestions on how to implement validation for this dropdown would be appreciated.

To create a personalized field in your array object, simply add it as a key.

dropdownconfig = {
    displayKey: "custom",
    search: true,
    placeholder: "Select User",
    height: "150px"
  };


  allUserData = [
    { firstName: 'first1', lastName: 'last1'}, 
    { firstName: 'first2', lastName: 'last2'},
    { firstName: 'first3', lastName: 'last3'},
    { firstName: 'first4', lastName: 'last4'}
  ]

  ngOnInit() {
    for (let user of this.allUserData) {
      user['custom'] = user.firstName + ' ' + user.lastName;
    }
  }

The library currently has a similar question open for discussion, so please avoid redundancy. If interested, you can view the ongoing conversation here. Below is a workaround that I have extracted.

To personalize your array/object, consider creating a custom property. For instance:

Suppose you have an array/object named Person with properties (id, firstName, lastName, age).
Add a new custom property called name to the Person object and populate it with values: firstName + lastName
Now utilize the updated Person object (now including name) with dispayKey set as: name

To merge data by adding a new key, iterate through the array/object. For example:

users.forEach((user) => {
    user.name = user.firstName + user.lastName;
});
