How can i display all tags registered in the clouddb in a listview?
What you do to display ALL Tags depends on how the tags are saved in the CloudDB.
If you have a List of Tags; this could be as simple as
set ListView_data.Elements to value.
Provide an example of how you save the CloudDB tags in the database and someone might help you with the code. to populate the ListView.
See User Interface
am simply storing them like that
so it would be helpful for an admin user to see all tags registered
so i thought if i added that tag, it would show everything in the value

You are presently storing each item of a user as
- name
- password
- job
You should be storing this type of information as a List, not as individual Tags.
email, name, password, job
You can use Blocks similar to these to find what you have stored in the CloudDB.
The top two will get you a List of tags in use
The bottom pair of Blocks will tell you what is in each tag if you use your present system (which is a bad idea). You should be saving this information as a List.
