1)intially set false to the div ,make it true after api returns data.see bellow eg:
 html:
 
 

    
 
 
 ts:
 getPostStatus() {
    this.api.getPostStatus("POST_STATUS").subscribe(
      (res) => {
        this.postStatus = res.results;
        this.postModel.postStatus = this.postStatus[0].lookup_value
      for(let i=0;i {
        console.log("no data available for GOOGLE_RATING");
      }
    );
  }
