Entity Name Picker

Overview​

This picker is introduced to set a default variable for your input field (usually you want this to be the name input field).

Configuration​

Along with that, as some pickers already do, you can define ui:options: allowArbitraryValues: false to block the user input on that field. Furthermore it's possible to define maxLength to limit the number of characters. The whole picker definition (inside template.yaml) would look something like this:

name:
  title: Name
  type: string
  ui:field: EntityNamePicker
  default: <your_default_value_goes_here>
  ui:options:
    allowArbitraryValues: false
    maxLength: 20
