Fields

On this tab you can modify the data fields (columns) of the document type.

•Move up () - moves the field up, which changes its position in the editing form displayed for documents of this type.

•Move down () - moves the field down, which changes its position in the form.

•New category () - creates a new category for fields. Fields belonging to a category are grouped together and displayed under a header in the form. Each category will contain the fields defined below it.

•New system attribute () - adds a new field used to display the value of a system field.

•New attribute () - adds a new field.

•Delete item () - deletes the currently selected field or category.

Under the list of fields, you can use a drop-down list to specify the following two properties:

•Document name source field - the system assigns the value of the field that you choose as a document name.

•Document alias source field - the system assigns the value of the field that you choose as the primary document alias. Note that you cannot change the document alias of existing documents by changing the Document alias source field—this setting applies to new documents only.

In the right hand part of the tab, you can specify the following properties for the currently selected field:

Please note: Not all options may be available depending on the selected Attribute type.

Database
Group	This option is displayed only when adding or editing a system attribute. It is used to specify which type of columns will be available for selection. There are two possible options: •Document attribute - offers the system fields of documents. •Node attribute - offers the system fields of document's content tree nodes.
Column name	Sets the name used for the database column storing the values of the field. It also serves as an identifier for the field.
Attribute type	Type of value that the field should contain.
Attribute size	Sets the maximum amount of characters that can be entered into the field. Only available if the Attribute type is set to Text.
Allow empty value	If enabled, the field allows empty values. If disabled, users cannot save the editing form unless there is a value entered in the given field. In this case, the field is required and an asterisk (*) is displayed next to it.
Default value	Default value of the field that will be pre-filled when documents of this type are created.
Translate field	Indicates if the field should be included when translating documents of this type using translation services. Only available if the selected Attribute type is Text, Long text or File.

Field appearance
Field caption	Sets the text displayed in the editing form next to the field.
Form control	Selects the form control that should be used in the editing form to interact with the given field. If the form control that you need is not available in the drop-down list, you should be able to assign it through the dialog opened via the (more items ...) option.
Field description	Tooltip which will be displayed if a user hovers over the field.
Editing control settings
The settings in this section are used to perform additional configuration of the selected Form control, which affects the behavior or appearance of the field. The available options depend on the parameters defined for the given form control. Please see the tooltips of individual settings for more information. This section also has two available modes. You can switch between Advanced and Simplified mode using the link on the side of the section. In simplified mode, only a limited set of parameters is offered (typically the most important ones).
Validation
Spell-check this field	If enabled, this particular field will have the option of being spell checked when editing documents of the given type on the Form tab in CMS Desk -> Content -> Edit. Only available if the selected Attribute type is Text or Long text.
Regular expression	This regular expression will be used by the validator of the field. Only available if the selected Attribute type is Text or Long text.
Min/Max length	Sets the minimum/maximum length for entered values. Only available if the selected Attribute type is Text or Long text.
Min/Max value	Sets the minimum/maximum value that can be entered. Only available if the selected Attribute type is numerical.
From/To	Can be used to specify a time interval into which the entered value must belong. Only available if the selected Attribute type is Date and time.
Error message	Error message displayed if a user enters invalid input into the field and attempts to save the form.
CSS styles
Caption style	Used to set CSS styles for the caption of the given field.
Input style	Used to set CSS styles for the input entered into the field.
Control CSS class	Name of the CSS class used to style the field.
Field advanced settings
Visible condition	May be used to enter a macro condition that must be fulfilled in order for the specific field to be visible in the editing form. You can write any condition according to your specific requirements. For details about available macro options and syntax, please refer to the Development -> Macro expressions chapter of the Developer's Guide. If you wish to create a condition that depends on the state of the document type's other fields, you can access them in the macro expression using the corresponding Column name. The data of the fields may then be retrieved through the following properties: •Value - returns the current value of the field. For example, NewsTitle.Value is resolved into the value entered into the NewsTitle field. •Visible - returns a true value if the given field is currently visible in the form. •Enabled - true if the field is currently enabled, i.e. its value can be edited. •Info.<field setting> - may be used to access various settings configured for the field, for example: NewsTitle.Info.Caption
Enabled condition	Allows you to enter a macro condition that determines when the field should be enabled. If this condition is resolved as false, the field will be visible, but it will not be possible to edit its value. You can use the same macro options as described above for the Visible condition property.
Has depending fields	If enabled, the editing form will be refreshed via autopostback whenever the value of the given field is changed. This means that other fields can be dynamically updated according to the current value of the field. Please note that the actual logic of the dependencies needs to be implemented in the code of the used form controls.
Depends on another field	This option must be enabled if you wish to have the behavior of the field dynamically changed according to the value of some other field.

The following properties are available when creating or editing categories:

Category
Category name	Sets the name of the category that is displayed in the editing form.
Collapsible	If enabled, users will be able to collapse and expand the content of the category.
Collapsed by default	If enabled, the category will initially be collapsed when the form is loaded.
Visible	Indicates if the category and all of the fields under it should be visible in the form.
Visible condition	May be used to enter a macro condition that must be fulfilled in order for the category to be visible. You can use the same macro options as described above for the Visible condition property of fields.

Any changes made to the settings of a field or category must be confirmed by clicking the Save button at the top.

Detailed information about document types and transformations can be found in Developer's Guide -> Development -> Document types. Please refer to Developer's Guide -> Development -> Form controls to learn more about form fields and their configuration.
