How can I convert input text on HTML to individual box-like structures each time user types a word s-CodePudding

I would like to know how I can convert text data into individual boxes as shown in the picture each time user enters a word separated after a comma (I am currently creating this as an input field on Angular)

You can simply use a variable with ngModel and a *ngFor over this variable.split(',')

<input [(ngModel)]="name">
<ng-container *ngIf="name">
  <div *ngFor="let item of name.split(',')">
    {{item}}
  </div>
</ng-container>

NOTE: You can use mat-chip-list in the way

<mat-chip-list *ngIf="name">
  <mat-chip
    *ngFor="let item of name.split(',');let i=index">
    {{ item }} 
    <button matChipRemove>
    <mat-icon (click)="remove(i)">cancel</mat-icon>
  </button>
  </mat-chip>
</mat-chip-list>

where

  remove(index:number)
  {
    const list=this.name.split(",") //get the list
    list.splice(index,1)       //remove the element at position "index"
    this.name=list.length?list.join(','):null  //give value to name using join
  }

stackblitz

NOTE: If you only need the "list" based in a variable just give value to the variable

Looks like you are looking for something like Angular Material Chips. https://material.angular.io/components/chips/examples
