Views might not always appear where you expect them to. The main applicability of views depends on the view subject and the inventory view.

List View
When you navigate through the environment tree, you can see the List view at the subjects that you specify during the view configuration and at their object containers. Depending on the inventory view, the List view might be missing at the object containers. For example, you create a List view with subject Host System. When you go to Environment > Object Browser > Environments > vSphere > vSphere Hosts and Clusters > vSphere World, select a vCenter Server, and click the Details tab, you can see your List view. If you go to Environment > Object Browser > Environments > vSphere > vSphere Storage > vSphere World, select the same vCenter Server, and click the Details tab, your List view is missing. Your List view with subject Host System is missing because the object Host System is not included in the vSphere Storage inventory view.
Summary View
When you navigate through the environment tree, you can see the Summary view at the subjects that you specify during the view configuration and at their object containers. Depending on the inventory view, the Summary view might be missing at the object containers. For example, you create a Summary view with subject Datastore. When you go to Environment > Object Browser > Environments > vSphere > vSphere Storage > vSphere World, select a vCenter Server, and click the Details tab, you can see your Summary view. If you go to Environment > Object Browser > Environments > vSphere > vSphere Networking > vSphere World, select the same vCenter Server, and click the Details tab, your Summary view is missing. Your Summary view with subject datastore is missing because the object Datastore is not included in the vSphere Networking inventory view.
Trend View
When you navigate through the environment tree, you can see the Trend view only at the subjects that you specify during the view configuration. For example, you create a Trend view with subject Virtual Machine. When you navigate to a virtual machine in the navigation tree, you see your view.
Distribution View
When you navigate through the environment tree, you can see the Distribution view only at the object containers of the subjects that you specify during the view configuration. Depending on the inventory view, the Distribution view might be missing at the object containers. For example, you create a Distribution view with subject Host System. When you go to Environment > Object Browser > Environments > vSphere > vSphere Hosts and Clusters > vSphere World, select a vCenter Server, and click the Details tab, you can see your Distribution view. If you go to Environment > Object Browser > Environments > vSphere > vSphere Networking > vSphere World, select the same vCenter Server, and click the Details tab, your Distribution view is missing. Your Distribution view with subject Host System is missing because the object Host System is not included in the vSphere Networking inventory view.
Text View
When you navigate through the environment tree, you can see the Text view only at the subjects that you specify during the view configuration. For example, you create a Text view with subject vCenter Server. When you navigate to a vCenter Server in the navigation tree, you see your view. If you did not specify a subject, you see your view for every subject in the environment.
Image View
The Image view is applicable for every object in the environment.
Note: Views applicability depends also on your user permissions and the view Visibility configuration.
