How to set order of Grouping Field in Format Settings I'm on D7. I have a taxonomy "projects". A project can be "ongoing" or "completed. I currently have a view that get's all projects (projects are a taxonomy/vocabulary). The "ongoing" and "completed" are project types which are also a taxonomy/vocabulary.

In the view, I set Grouping field Nr.1 to Taxonomy Term: Project Type

I want to make sure that "ongoing" is above "completed". How can I do that? Somehow the order changed from "ongoing, completed" to "completed, ongoign" after I updated an ongoing project to completed.

The order of the taxonomy terms seem to not matter.
First, you can set the weight of the Project Type terms in the vocabulary.
Then you have to create the following relationship:

Entity Reference: Referenced Entity
A bridge to the Taxonomy term entity that is referenced via field_project_type

Then, add a Sort Criterion (first) Taxonomy term: Weight using the above relationship.
