Lists you created in Upsales can be sorted on columns, wherever there's an arrow next to the column name.
Click a column header to sort the list under the column. The column header changes colour to show that is how the information is sorted. An arrow also shows the direction of the sort (ascending or descending).
Click the column header again to sort in the opposite direction.
The sort is not saved automatically. The next time you open the list, it uses the list's saved sort order. To keep your sort, save the list: see How to save and share a list.
