Hello Worachit Sommut,
Thanks for the screenshot.
Yes this looks indeed a bit messy hahah :-).
To overcome this you can do multiple things use a layout grid, use a table, or use a datagrid this forces the information to start and end within the boundaries.
More information about the different options here;

Hope this helps,
Good luck!
Hello Worachit Sommut,
1. Make a different entity which is a generalization of system.FIleDocument
See also this how to: https://docs.mendix.com/refguide/configure-files/
2. For this point can you elaborate more and maybe add screenshots of what you would like to achieve and what at the momen the problem is
I want them to be in their own place. It's like there's a table covering it so it doesn't overlap other channels.
