Iframe widget in Sitecore

Sometimes due to legacy 3th party sites, you need you load some pages as Iframe to your website.
I just summarized the steps how to so it in Sitecore.

• creating template with url field in MVC. For that specific feature you create a template then you can have the url property in your component.

• Create a template class to use the url field in the view :

public class Templates
   {
  public struct widget
       {
           public struct Parameters
           {
               public static readonly string Url = "Url";
           }
       }
 }

• creating view in MVC

@using Sitecore.Mvc.Presentation
@using Feature.MyJourney
@using Foundation.SitecoreExtensions.Extensions
@using HtmlHelperExtensions = Foundation.SitecoreExtensions.Extensions.HtmlHelperExtensions
@model Sitecore.Mvc.Presentation.RenderingModel

<div class="responsive-iframe-container iframe-noBorder widget-iframe">
    <iframe scrolling="no" src="@Model.Rendering.GetStringParameter(Templates.widget.Parameters.Url)"></iframe>
    @if (Sitecore.Context.PageMode.IsExperienceEditor)
    {
        @Html.PageEditorInfo("widget. Current url is set to: " + Model.Rendering.GetStringParameter(Templates.widget.Parameters.Url))
    }
</div>

• create a new rendering associated to the new view path
  it is so important to set the Parameter Template to the new template.

• Changing the placegholder setting to allow new component

• Once you dropped the component on the page from Experience Editor' you can edit urlthroughmore button`
