Once created, content types can be edited to add or delete data fields
as necessary.
Sign in as a content administrator in your browser and click
Content under Administration in the left navigation
menu.
Select Content Types from the drop-down menu.
Select the content type to edit and click Edit in the
banner menu.
A slide-out panel shows the content type definition, displays the data
fields used in the definition, and lists additional data field
options.
Add additional data fields, edit settings for current data fields, or delete
current data fields.
To add an additional data field, drag the field from the list into the
definition and supply the requested settings just as you would when
creating a new content type.
To edit settings for a current data field, click
Edit next to the data field and change the
settings.
To delete a current data field, click the X next
to the data field.
Note:
If a content type has published content items
associated with it, then you cannot delete a data field from the
content type until those content items are unpublished. If a content
type has draft content items associated with it, deleting a data
field from the content type also deletes the values of that data
field in the associated content items.
