You will see a list of all pages for your website.

Step 2: Change the Order
Identify the item you want to move.
Click and drag the three lines on the left of the item to reorder it.
Release the item at the desired position.
The item will be reordered as you dragged it.

Step 3: Refresh to Apply Changes
