Need assistance writing example code for part of a web page

I have a Yii2 basic web application. It has a detail view of a Project. On that page it has a GridView (Krajee) displaying Project Risks. They currently load using Pjax. The example project is too large to upload and may be downloaded from http://www.phpbizapps.com. I need someone to write code to accomplish the following additional features. 1. On the Project Risk GridView section on the Project detail (view) page: a) Change Probability and Impact display from integer value to display text (1=Low,2=Medium,3=High) based on the integer value stored in that field. b) Change Status display from integer to text of Status object. 2. Make table rows editable using Pjax to prevent page reload (Pjax is already enabled in the Grid); a) The Probability, Impact, and Status fields will use Drop Down List inputs (1=Low,2=Medium,3=High). b) The Status values come from Db (model & controller already present, foreign key already configured in project & project risk objects. c) Description and Mitigation will use text inputs (multi-line). 3. Create a Bootstrap Modal from the 'Add New' button. On new Risk save, refresh Risk list on save using Pjax. End.
