Extra Fields in Grid View

Hi all,
In Print page Item Grid View unable to show the number of columns more than five. Is there any restriction in showing the number of columns. also can we customise the grid view.

No column restriction in print format.

Also bootstrap uses 12 column grid format. but no restriction of column number.

Grid views can be customized. Check erpnext/item_grid.html at develop · frappe/erpnext · GitHub
