Expression Example

By using a param with the type expression, it is also possible to display the values returned by a service (Display values from a service in a select).

Note

Be aware that the provided expression is only evaluated during the initial request to the administration interface. If you want to provide a selection for your custom entity, you should configure the single_selection field-type as described in Extend Admin UI.

<property name="single" type="single_select">
    <meta>
        <title lang="en">Single Select</title>
    </meta>

    <params>
        <param name="default_value" type="expression" value="service('App\\Content\\Select\\EventTypeSelect').getDefaultValue()"/>
        <param name="values" type="expression" value="service('App\\Content\\Select\\EventTypeSelect').getValues(locale)"/>
    </params>
</property>
