Open the store in Settings → Stores — or, on your list, touch and hold the store’s button at the top and choose Edit (with the store’s name). If it has no aisles yet, tap Add Standard Aisles for 22 common ones, or Add an Aisle to type your own. Then type in Add an aisle and press Return to keep adding. Touch and hold an aisle to move it, or swipe it to the left to delete it. Tap the checkmark (or Done) when you’re done.

Tap an aisle to rename it and to see what’s in it. Add Items puts several items in the aisle at once. Swipe an item to the left to take it out, or touch and hold it to move it to another aisle. A new aisle can take items once the store is saved.

You don’t have to get the order right the first time. After a few shopping trips, Menu Planner 2 can offer the order you actually walk.
