You can create several types of lists.
Pages detects when you’re creating a list if you begin a sentence with a dash, number, or letter.
Tap where you want your list to begin, type a dash, or a letter or number followed by a period (1. or A.), then type the first item.
Tap Return.
Pages automatically adds a bullet, letter, or number to the subsequent items in the list.
To change the indentation level (hierarchy) of the item, tap 
in the shortcut bar above the keyboard, then tap Indent or Outdent.
To end the list, tap Return twice.
To change the list style, select all of the list items, tap 
, tap List, then tap a new list style.
To adjust list spacing, select the list items, tap , tap Layout, then use the Line Spacing arrows to increase or decrease spacing.
You can drag items in a list to a different level in the hierarchy or to a different indentation level. (You can’t drag list items if change tracking is turned on.)
Touch and hold the bullet or symbol at the beginning of the line.
Drag the item up or down in the list, or drag it to the left or right, until you see a blue triangle where you want the item.
