How can I use a select-field?

[peterschoene]

Hello, I tried to add a new select-field in my femanagerextended.
Here is what I did:
TCA
'my_new_option' => [
'exclude' => false,
'config' => [
'type' => 'select',
'renderType' => 'selectSingle',
'items' => [
['Keine Auswahl', '0'],
['First option 1', 'fo1'],
['Second option 2', 'so2'],
... etc...
],
'size' => 1,
'maxitems' => 1,
'eval' => ''
],
],

Added myNewOption to my model (and database of course)
Added a partial like this:

<femanager:form.select id="femanager_field_mynewoption" property="myNewOption" defaultOption="{f:translate(key:'pleaseChoose')}" class="form-control" additionalAttributes="{femanager:Validation.FormValidationData(settings:settings,fieldName:'myNewOption')}" />

Unfortunately no option appears in FE.
What should I add?
Thank you for your help.

I figured out:

<femanager:form.select
id="femanager_field_my_new_option"
options="{femanagerextended:Form.GetMyNewOption()}"
property="myNewOption"
prependOptionLabel="{f:translate(key:'pleaseChoose')}"
class="form-control"
additionalAttributes="{femanager:Validation.FormValidationData(settings:settings,fieldName:'myNewOption')}" />
