I am working on a React project where I have used CKEditor 4 on Material UI dialog. When I am trying to use advance options like Math. I am not able to type in, anything on input, textarea fields. I have searched for solutions but all the solutions are with respect to Bootstrap Modal. If anyone has faced the same issue using the Material UI dialog. It will be a great help if you can share the solution.
