Make edits and make a conclusion from the backend to the frontend (Yii2)

Good afternoon. There is a site with ready-made functionality (admin) added new functionality (entry of the object) you need to bring this functionality to the front and make small edits. The conclusion should be made only for part of the functionality (entering the object). All entry will be displayed on one page of the site.
Sketches and icons for the front will provide. http://conerunt.ru/ its a website.
