Your common child modal component will be as below

import {Component,Input, ViewChild} from '@angular/core';
import { ModalDirective } from 'ng2-bootstrap/ng2-bootstrap';

@Component({
  selector: 'common-modal',
  template: `
   

  

    

      

        
{{title}}
        
          ×
        
      
      

         
      

      

        

           Cancel 
        
      
    
  

  `,
})
export class CommonModalComponent {
   @ViewChild('childModal') public childModal:ModalDirective;
   @Input() title:string;
  constructor() {
  }
  show(){
    this.childModal.show();
  }
  hide(){
    this.childModal.hide();
  }
}

Using the child component in your parent component will look as below

import {Component, ViewChild, NgModule,ViewContainerRef} from '@angular/core'
import { BrowserModule } from '@angular/platform-browser';
import { ModalDirective,ModalModule } from 'ng2-bootstrap/ng2-bootstrap';
import {CommonModalComponent} from './child.modal';
@Component({
  selector: 'my-app',
  template: `
    Open modal

  `,
})
export class AppComponent {
  @ViewChild('childModal') childModal :CommonModalComponent;
  constructor(private viewContainerRef: ViewContainerRef) {
  }

}

Using the above code you can have a separate common modal dialog which can be reused, so that your header & footer remains the same and you can use Content-Projection to use change the body of the modal dialog.
