Can I configure a SharePoint list to sort by legal or outline numbering?

[jenbaier81]

Example would be items with values as follows in a number column:

1.0 Main Topic

1.1 Subtopic

1.11 Sub-subtopic

And so on. My brain hurts, I have not been able to find a viable solution to this as the Number column type does not allow for more than one period or decimal point.

@jenbaier81 the only way to do this is with a single line of text column. But given that SharePoint sorts from left to right you will need to make sure your numbering is 1.0, 1.01, 1.02, 1.11 etc.

Rob, you are an absolute lifesaver. Such a simple solution!
