1. Decide which type of scroll you want to create: vertical or horizontal
2. If vertical, choose the specific header/component inside the frame that you want to fix on the top edge
   1. Go to Prototype and under Scroll behavior, choose Position → Sticky (stop at top edge)
3. Select the big frame and under Scroll behavior, choose Overflow → Vertical
4. If horizontal, choose the specific column/component inside the frame that you want to fix
   1. Go to Prototype and under Scroll behavior, choose Position → Fixed (stay in place)
5. Select the big frame and under Scroll behavior, choose Overflow → Horizontal
6. Done!
