selectCheckBox

Only useful if foreign_table is enabled.

If set, then values which are not integer ids will be allowed. May be needed if you use itemsProcFunc or just enter additional items in the items array to produce some string-value elements for the list.

Authorization mode for the selector box. The only possible option is:

explicitAllow

All static values from the "items" array of the selector box will be added to a matrix in the backend user configuration where a value must be explicitly selected if a user (other than admin) is allowed to use it!)

The maximum size (height) of the select field.

The size of the select field will be automatically adjusted based on the number of selected items. The select field will never be smaller than the specified size and never larger than the value of autoSizeMax.

Default value set if a new record is created. If empty, the first element in the items array is selected.

If set, then no element is inserted if the current value does not match any of the existing elements. A corresponding options is also found in Page TSconfig.

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.

For details see fieldInformation.

The item-array will be filled with records from the table defined here. The table must have a TCA definition.

The uids of the chosen records will be saved in a comma separated list by default.

Use property MM <columns-select-checkbox-properties-mm> to store the values in an intermediate MM table instead.

This property references a specific field in the foreign table, which holds an item group identifier.

See also foreign_table_item_group.

Label prefix to the title of the records from the foreign-table.

The items from foreign_table are selected with this WHERE clause. The WHERE clause is effectively appended to the existing WHERE clause (which contains default constraints, such as NOT deleted) and must begin with AND.

Contains an array of key-value pairs. The key contains the id of the item group, the value contains the label of the item group or its language reference.

Only groups containing items will be displayed. In the select field first all items with no group defined are listed then the item groups in the order of their definition, each group with the corresponding items.

Item groups are rendered as <optgroup>.

Item groups can also be defined for items in foreign tables.

See also Item group API methods

Contains the elements for the selector box unless the property foreign_table or special has been set in which case automated values are set in addition to any values listed in this array.

Items registered for the field CType of table tt_content get automatically added to the New content element wizard. Settings from the items property can be overridden via page TSconfig newContentElement.wizardItems.

See also Add content elements to the Content Element Wizard.

Each element in this array is in itself an associative array.

label (string or LLL reference)

The displayed title.

value (integer or string)

The value stored in the database.

• The special value --div-- was used to insert a non-selectable

  value that appears as a divider label in the selector box. It is kept for backwards-compatible reasons. Use item groups for custom selects instead.

• Values must not contain , (comma) and | (vertical bar). If you want to use authMode, you should

  also refrain from using : (colon).

icon (EXT: path or icon identifier)

Optional icon. For custom icons use a path prepended with EXT: to refer to an image file found inside an extension or use an registered icon identifier. If configured on the foreign_table, selicon-field is respected.

group (string)

The key of the item group.

description (string or array)

Fifth value is an optional description text.

PHP method which is called to fill or manipulate the items array. See itemsProcFunc about details.

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.

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

This value contains the name of the table in which to store a MM relation. It is used together with foreign_table.

The database field with a MM property only stores the number of records in the relation.

Please have a look into the additional information in the MM common property description.

Array of field => value pairs to both insert and match against when writing/reading MM relations.

If you want to make a MM relation editable from the foreign side (bidirectional) of the relation as well, you need to set MM_opposite_field on the foreign side to the field name on the local side.

For example, if the field companies.employees is your local side and you want to make the same relation editable from the foreign side of the relation in a field called persons.employers, you would need to set the MM_opposite_field value of the TCA configuration of the persons.employers field to the string "employees".

In a MM bidirectional relation using match fields the opposite side needs to know about the match fields for certain operations (for example, when a copy is created in a workspace) so that relations are carried over with the correct information.

MM_oppositeUsage is an array which references which fields contain the references to the opposite side, so that they can be queried for match field configuration.

Additional where clause used when reading MM relations.

Example:

{#uid_local} = ###THIS_UID###

The above example uses the special field quoting syntax {#...} around identifiers to be as DBAL-compatible as possible.

If the "multiple" feature is used with MM relations you must set this value to true and include a UID field. Otherwise sorting and removing relations will be buggy.

Allows the same item more than once in a list.

If used with bidirectional MM relations it must be set for both the native and foreign field configuration.

The property MM_hasUidField has to be defined when using multiple.

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

Size of the input field.
