type => 'select' // TCA alternativeSql: true

The Select type generates a simple select field.

Settings¶

renderType¶

Required: yes
Type: string

selectSingle
selectCheckBox
selectSingleBox
selectTree
selectMultipleSideBySide

items¶

Required: yes
Type: array

Contains the elements for the selector box. Each item is an array with the first being the label in the select drop-down (LLL reference possible) and the second being the value transferred to the input field.

Example:

items:
  - label: 'The first'
    value: one
  - label: 'The second'
    value: two
  - label: 'The third'
    value: three

default¶

Required: false
Type: string

Default value set if a new record is created.

maxitems¶

Required: false
Type: integer

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. If maxitems ist set to greater than 1, multiselect is automatically enabled.

minitems¶

Required: false
Type: integer

Minimum number of child items. Defaults to 0. 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.

For more advanced configuration refer to the TCA documentation.
