Valid values of itemtype

Question

What are the different values for the itemtype?

Answer

1. content
2. matadata
3. layout
4. options

The itemtype in the definition defines the section where the defined mixin/properties will appears.

E.g.:

[jmix:cache] mixin
 itemtype = options
 extends = jnt:content
 - j:expiration (long)
 - j:perUser (boolean)

means the cache section with properties j:expiration and j:perUser will appear into the options in the edit screen of every jnt:content.
