Relation 

One or more tables, that should be referenced.

This table can be defined by another Content Block, but can also be an existing table defined by the Core or another extension.

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

Minimum number of items. Default is no minimum. JavaScript record validation prevents the record from being saved if the limit is not satisfied. The field can be set as required by setting minitems to at least 1.

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.

The field will never grow larger than this number of visible rows.

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

Default value set if a new record is created.

A list of tables which should not be remapped to the new element uids if the field holds elements that are copied in the session.

Changes the default starting point when opening the element browser. Use the key _default to set the default page uid.

Example:

elementBrowserEntryPoints:
  _default: 42

Enables or disables individual controls next to the field. Each control accepts a disabled boolean. Available controls: addRecord, editPopup, listModule, elementBrowser, insertClipboard.

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.

Restricts selectable records to a specific table. Can be used instead of or together with allowed.

Removes the delete icon next to the selector box.

Removes the move icons next to the selector box.

Disables the suggest (autocomplete) wizard.

Defines whether referenced records should be localized when the current record gets localized. Only applies if references are not stored using MM tables.

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

Field-value pairs to both insert and match against when writing/reading MM relations.

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

Required on the opposite side of a bidirectional MM relation that uses match fields.

Additional WHERE clause used when reading MM relations.

Allows the same record to be selected more than once in the list.

When enabled, the table name is prepended to the stored relation uids.

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

Number of visible rows in the selector box. A value of 1 displays a drop-down.
