Actions for Assigned Domains

There are two options when you click the three dots on the domain for the parent and child:

Unassign 
This option will unassign the domain and move it back to the Unassigned Domain panel.
Change Parent 
This gives the option to move the child from one domain to another parent within the Assigned Domains panel.

Important:If you select either one of these options on the parent domain level, it will affect its children's domains.
