Load HTML Content Via AJAX in Angular ListView component

We can set external HTML page content as template for our ListView component by making use of AJAX call.

let ajax = new Ajax('./template.html', 'GET', false);
    ajax.onSuccess = (e)=>{
        this.listtemplate = e;
    };
    ajax.send();

In the below sample, we have rendered smartphone settings template from external HTML file.
