Using json with Framwork7 Virtual List

I’m want to use json to get data and render it in Virtual List using Framework7

I was able to get the data using javascript

    .then(function (response) {
        return response.json();
    .then(function (data) {
    .catch(function (err) {
        console.log('error: ' + err);
function appendData(data) {
    var mainContainer = document.getElementById("myData");
    for (var i = 0; i < data.length; i++) {
        var div = document.createElement("div");
        div.innerHTML = 'Post: ' + data[i].id + ' ' + data[i].title.rendered;

By using the documentations here Virtual List Its very hard to display the data on the list and I’m always get console errors

Наоборот, Virtual List это крайне крутая штука. Покажите ваш код.

The code i’m using the code above to retrive data from json
But I want to render it using virtual list
