in row 1 I have a lot of headers for data which I want to enter in row 2. To avoid horizontal scrolling I want to use Data → Forms.
The Forms window is however limited to my screen height and doesn’t allow vertical scrolling. The scroll bar is there, but it’s greyed out. If I change the vertical window size, the number of columns I can enter data for adjusts to the height, but no scrolling is possible so I can’t enter data for all columns in the sheet.
