Hi Jorge,

Expected output Image should be like below while editing a row: We have took the below screen shot while running the sample that has been modified by you.
Can you please ensure whether you have refer the individual dependency script files. If so it is necessary to refer the dependency file “ej.dialog.js”/ ej.dialog.min.js because you have set editType as dropdown for ShipCountry column so that while enable the Editing feature in the grid it renders properly.
For your convenience please refer the below documentation link,
Note: For your kind information, we are not able to reproduce the above reported issue in the sample that you have modified and sent to us.
If you still face the issue please provide the below information which will be helpful for us to analyze about the issue and update the response as early as possible,
1. Open the developer tool in your browser and check if any script error occurs in the console window. If any script error occurs please expand it and send the screen shot.
