React Forms:

Dynamic User List Form with React and Bootstrap

You can use this simple but very useful code to manage the website user. In this post we have two forms. The first form on the left side of the page takes the details of the new users and enters them into the users' licenses. The list of users is written on the right side of the page. There is also a drop-down list in the middle of the page that includes all users. By selecting each user from the items in the list, the user profile can be edited.
