You can change the order of labels displayed on the sub-navigation of the Manual section. When viewing a procedure, click on the "labels" icon and then click the "Edit Label" link.
When there are two straight lines against the left of each label, you are able to drag and drop the label into a reordered position.
Labels can also be dragged into an indented position to create sub-Labels under a primary Label. Way We Do allows for unlimited sub-Labels.
