Hi @trung.le

I am currently encountering a similar challenge in another application where we are experiencing difficulties in modifying or utilizing the default margin settings.

If you have come across a solution for a similar issue or can provide guidance on how to address this matter, I would greatly appreciate your assistance.

Thanks & Regards,

Hi @trung.le ,

Good Day!

Have you received any solution for this issue? If so, please share it with me.

Hi Gopi,
So far, I have no solution. I just leave the bar there, blank and useless.
