Sharepoint - Sorting grouped items in a list view

Simplest possible solution is to include section number in group field:

1. Permissions
2. Requirements

Problem is that you can apply sort on groups only on group field. So if you use number in front of group name you can get desired results.

For other people who run into the issue of ordering Groups but do not want to add any other (visible)characters to the title here is a small tip.

Add spaces! More than one space is not shown in HTML so adding multiple can be done without harming the layout of the lists in most places. Spaces will be sorted to the top, so the title with most spaces in the beginning will be the first, the heading with second most spaces will be the second from the top, etc.

We needed to order a series of headers with names that did not sort alphabetically and did it like this:

  Heading one
 Heading 2
Heading 03

When displayed in the list it will look like this:

Heading one
Heading 2
Heading 03
