By default, your Collection items show in the same order as the rows in your table. However, you can use Sort to change this order.
Default sort
Select a collection you'd like to sort. In the Options tab on the right of the Layout Editor, you'll see Sort by table order under Sort Data. You can click on this text to customize how your collection is sorted.
In addition to the default table order option, you can choose to sort randomly or by the values in any column from the table. Your list will be sorted either alphabetically or numerically depending on the data in the column you choose. You can reverse the order of your current sort by clicking the up or down arrows on the right at any time.
Sorting can make more sense of the data in your collections. For example, the app below shows a list of products sorted by price in descending order.
