Working on exsiting project

We have a project build by ASP .Net core backend and frontend, We need an expert one to add some right-click context menu functionality on some HTML tables. The front end is .chtml files (Views), I think MVC developer is the best candidate with this task. So the person who can work on this task must have some experience in HTML, CSS, JAVASCRIPT, JQUERY. We have an example and we need the same in our project, you can check the following link: [login to view URL] It must be responsive and worked perfectly with all browsers, just you must check the above example and copy it inside our project. The work will be remote, We used TeamViewer or any desk, so we will give you access to computer and start working directly.
