Collection 

Defines which field should be used as the title of the record. If not defined, the first valid child field will be used as the label. It is possible to define an array of fields, which will be displayed comma-separated in the backend.

# a single field for the label
labelField: title

# multiple fields will be displayed comma-separated
labelField:
    - title
    - text

Defines which fields should be used as fallback, if labelField is not filled. The first filled field which is found will be used. Can only be used if there is only one labelField field defined.

# fallback fields will be used, if title from labelField is empty
labelField: title
fallbackLabelFields:
    - text1
    - text2

Alternative table name for the Collection. Default is identifier with prefix if enabled.

table: tx_vendor_my_custom_table_name

Configures a set of fields as repeatable child objects. All fields defined in field types are possible as children. It is also possible to further nest Collection fields.

Example:

fields:
  - identifier: text
    type: Text
  - identifier: image
    type: File

Minimum number of child items. Defaults to 0. JavaScript record validation prevents the record from being saved if the limit is not satisfied.

Maximum number of child items. Defaults to a high value. JavaScript record validation prevents the record from being saved if the limit is not satisfied.

The relationship defines the cardinality between the relations. Possible values are oneToMany (default), manyToOne and oneToOne. In case of a [x]toOne relation, the processed field will be filled directly with the record instead of a collection of records. In addition, maxitems will be automatically set to 1.

• Default (null): Last collapsed/expanded state is remembered
• true: Show all child records collapsed
• false: Show all child records expanded

Defines where to show the "New record" link in relation to the child records. Valid keywords are top, bottom and both.

When enabled, only one child record is expanded at a time. Clicking a collapsed record collapses the currently open one.

Show or hide the "New record" link.

Adds the title of the foreign table to the "New record" link label.

Overrides the "New record" link label with a localized string. Only takes effect if appearance.newRecordLinkAddTitle is not set to true.

Overrides the "Create new relation" button label with a localized string. Only useful when the element browser is enabled.

Enables editing of intermediate table attributes alongside the related child record in bidirectional relations. Requires foreign_selector and foreign_unique to be set to the same field.

Suppresses the warning message shown when appearance.useCombination is active.

Activates drag & drop sorting of child records.

Show unlocalized records that exist in the original language but have not yet been translated.

Show a "Localize all records" link to fetch untranslated records from the original language.

Show a "Synchronize" link to update to a 1:1 translation with the original language.

Enables or disables individual controls on child records. Available keys with their defaults:

info (bool, default true)

Show or hide the info control.

new (bool, default true)

Show or hide the "new" control.

dragdrop (bool, default true)

Show or hide the drag & drop handle.

sort (bool, default false)

Show or hide the sort arrows.

hide (bool, default true)

Show or hide the hide/show toggle.

delete (bool, default true)

Show or hide the delete control.

localize (bool, default true)

Show or hide the localize control.

Example:

appearance:
  enabledControls:
    sort: true
    delete: false

Hides the foreign record selector from the interface even when foreign_selector is configured. Useful when replacing the selector with a custom control via customControls.

Shows or hides the element browser button in inline records.

It is possible to reference another table instead of creating a new one. This table can be defined by another Content Block, but can also be an existing table defined by the Core or another extension.

It is possible to override the field name pointing to the parent record. Per default it is called foreign_table_parent_uid. This corresponds with the TCA option foreign_field.

Allows to reference a Record Type across multiple tables, if foreign_table is used.

Make sure to add this to every Collection, which shares the foreign_table.

This will create a new field called tablenames. It corresponds to the TCA option foreign_table_field. The field name can be overridden by defining foreign_table_field explicitly.

Allows to reference a Record Type across multiple fields, if foreign_table is used.

Make sure to add this to every Collection, which shares the foreign_table.

This will create a new field called fieldname. It corresponds to the TCA option foreign_match_fields.

This option allows you to restrict possible record types for the type selector of the child record. The order of definition is used to sort the items. The first item in the list will always be the default type.

allowedRecordTypes:
  - text
  - images

The inline field will never grow larger than this number of items before a scrollbar appears.

Allows to select if localization uses custom or default language value.

Disables automatic moving of child records when the parent record is moved.

When disabled, child records are not deleted when the parent record is deleted.

A list of custom controls (user functions) used to extend the inline field interface. Each entry requires a userFunc key.

See TCA fieldControl.

See TCA fieldInformation.

See TCA fieldWizard.

Defines filters for item values. Each entry requires a userFunc key and an optional parameters object. Does not work in combination with a wizard.

ORDER BY clause for sorting child records when foreign_sortby is not defined.

Field name of the child record to use as the inline element title.

Field-value pairs inserted into and matched against when writing/reading IRRE relations. Allows reusing the same child table across multiple parent fields.

Field name of the child record used as a selector to show all possible related records.

Field on the child record that stores the manual sort order.

Field on the child record pointing to the parent table name. Used together with shareAcrossTables.

Field on the child record that must be unique across all children of a parent record.

Table name for storing the MM relation. Used together with foreign_table.

Enables bidirectional MM relations. Set to the field name on the local side when configuring the foreign side.

Overrides TCA configuration of child records (e.g. sys_file_reference) attached to this field.

Renders the field in a way that the user can see the value but cannot edit it.

Number of visible rows in the inline field.

Works like foreign_field for bidirectional symmetric relations. Defines the field storing the uid of the "other" parent.

Overrides the label defined in labelField when viewing a symmetric relation from the other side.

Works like foreign_sortby for bidirectional symmetric relations.

Type Overrides can be used to override the Record Definition in the context of as single field. This option only makes sense, if you don't define fields, but an external foreign_table, that you want to override. Refer to the API documentation if you want to learn more.
