به ازای هر آیتمی که در شیء بازگشتی وجود دارد، با استفاد از متد each در jQuery یک li ایجاد می‌کنیم. همان طور که می‌بینید کلیه خواص، به شکل Fluent قابل اضافه شدن می‌باشد. سپس برای li یک رویداد کلیک که در صورت وقوع، متد FillData را با شناسه فید کلیک شده فراخوانی می‌کند و در آخر li را به المنت ul اضافه می‌کنیم.

برای هر کلیک هم مانند مثال بالا api را با شناسه‌ی فید مربوطه فراخوانی کرده و به ازای هر آیتم، یک سطر ایجاد می‌کنیم.
