Auto scroll for list and forms which have many columns

Do someone help me please,
When we have a table which contains many columns or in add or edit with gridview
a part of this table does’nt appear.
Could someone help me please how to configurate this issue?

There is a horizontal scrollbar at the bottom of the table, it is Bootstrap responsive table, if you do not want it, you can click Tools → Advanced Settings and disable “Use Bootstrap responsive tables”.

OK it’s working but the top sidebar is cut and is not adjusted when the grid add page was adjusted with auto scroll.
Thanks

I assume “top sidebar” means the header, you need to adjust it yourself. That is why Bootstrap responsive tables are used by default.
