Each Content Type contains one or more fields which represent individual pieces of information for each individual content item of that Content Type. Fields may contain many different types of information (such as string, integer, floating point, etc.), and may be configured to display values and allow values to be entered in multiple different ways (e.g. as a text box, drop-down list, multiple select list, radio buttons, etc.).
You can add fields to any Content Type in dotCMS, even the Content Types that ship with dotCMS. This allows you to both create new Content Types with any fields you wish and to extend the Content Types that come with the base dotCMS installation by adding any additional fields you wish.
The fields in a Content Type (e.g. “columns” in the “table”) are comprised of the Standard Field Types, the WYSIWYG Field, Tag and Category Fields, etc. Nearly all fields can be made searchable, and can be accessed via the RESTful APIs.
The following summarizes the different types of fields which may be added to a Content Type:
|Field Display Type||Description|
