You need to bind data with some variable by parsing it into json() , then you will be able to fetch and consume data into your view like this

 ngOnInit() {
    this.CartdataService.get_New_Products().subscribe(
      data => {
        this.dropdownData = data.json();
                  console.log(data.json());
      });


<div class="col-sm-12" style="margin-top: 20px !important" *ngFor='let data of dropdownData; let i=index'>
    <div class="col-sm-12 opt1">
        <div class="row">
            <h5>
                <a class="col-sm-12 font-weight-normal">
          {{data?.CAMD_ENTITY_DESC}}
        </a> 
            </h5>
            <i class="fa fa-angle-down ind" data-toggle="collapse" [attr.href]="'#collapseExample' + data?.CAMD_ENTITY_DESC"></i>
        </div>
    </div>
    <div class="col-sm-12 collapse opt1" [id]="'collapseExample' + data?.CAMD_ENTITY_DESC"
  *ngFor='let group of data?.group; let j=index'>
        <div class="row">
            <h6>
                <p class="dropdown-item col-sm-10">{{group?.CAMD_PRGRP_DESC}} </p>
            </h6>
            <i class="fa fa-angle-down ind arrow" data-toggle="collapse" [attr.href]="'#innerCollapse' + group?.CAMD_PRGRP_DESC"></i>
        </div>
    <div class="collapse col-sm-12" [id]="'innerCollapse' + group?.CAMD_PRGRP_DESC">
        <div class="row" *ngFor='let subgroup of group?.subgroup; let i=index'>
            <h6>
                <a class="dropdown-item opt">{{subgroup?.CAMD_PRSGRP_DESC}}</a>
            </h6>
        </div>
