Move Categories
You can use the CategoryMove action to move individual categories in the category hierarchy. For example:
action=CategoryMove&Category=124365780934532&Parent=12398234987345876
In this example, the IDOL Category component moves the category that has the ID 124365780934532
to the category with the ID 123098234987345876
(to make category 12398234987345876
the new parent of category 124365780934532
).
