# Data fields

Some fields, such as *Object ID*, *Description, Revision, ...,* are fixed. Others can be attached/detached to the type tree.

Data fields are always inherited to subtypes. For example, if you connect an attribute to the ***Items*** type, it will be used in all its subtypes.

Additional fields can be created. The following field types are supported:

- **String** - Single line text
- **TextArea** - Multiline text
- **List** - Menu with selections
- **Decimal** - Decimal value
- **Integer** - Integer value
- **URL** - Clickable URL link
- **Querylist** - Object based list (E.g. Name dictionary)
