I was recently updating a view in a SharePoint List, the view was set up to use metadata fields to sort and group the content…lovely stuff. What I was required to do was to implement a choice field with a numerical order within it (i.e. 1. First step, 2. Second step, 3. Third step).
With sort order in List/Library views, it works with either alphabetical or numerical options ascending or descending. What I found was with choice fields operating as the number order, once you hit 10 the numbering system went out the window!
What you end up with is something like this:
1) First choice
11) Eleventh choice
12) Twelfth choice
2) Second choice
3) Third choice
and so on…
By default, SharePoint interperates the choice field as alphabetical so the way I got around this was to just use:
a)
b)
c)
This gets around any issues with numerical values over 10 or having to create lookup lists or anything else 🙂
