You know that everybody hates feedback forms and nobody wants to complete a long and ugly one? That's why Creative Tim came with a really light, beautiful and simple feedback form. You know that simple wins over complex. As Steve Jobsput it: “Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple.”

Creative Tim thinks it's important to let your users know where they are while completing a feedback form and so, he added the steps number that allow the user to move quickly and sequentially through the categories. Even if you only have a 10 steps form, for a better UX it's good to inform your user about the length of the form.
Our recommendation is to keep the feedback form on a separate page, with no headers/menus/ads or other items that can distract the user from his completing flow.
Take it, integrate it in your next project and be happy!
