Viewing REST V2 Resources in Group by Tags Mode
The REST Resources tab for a REST API descriptor displays the REST resources grouped by the resource name. If a REST API descriptor contains many REST resources, the REST Resources tab may appear cluttered. To provide a more organized view of the resources in a REST API descriptor, you can group the resources by tags.
Operations in a REST API descriptor are associated with a tag. When you view the REST Resources in a group by tags mode, Designer organizes all the operations (part of multiple REST Resources) under the tags associated with each operation. An operation can have multiple tags associated with it. In case of multiple tags, the operation is grouped under the first defined tag.
Any operation that does not have a tag associated with it, is grouped under the default tag.
To view REST Resources in Group by Tags mode
1. In the Package Navigator view, open the REST API descriptor for which you want to group the resources using the Group by Tags method.
2. Click the REST Resources tab.
3. Click 
on the top right corner of REST Resources tab. Designer displays the REST V2 resources in the Group by Tags mode.
