AbstractField with custom html template

Dear Team,

we are a bit confused at the moment. We try to implement a custom field containing multiple translations for one label. (TranslatableLabelField which consists of a textfield and a comboBox for the language switch)

Therefore we extended the AbstractField as described here: https://vaadin.com/docs/v14/flow/binding-data/tutorial-flow-field.html#combining-multiple-properties-into-one-value
Is it now possible to have a custom html template, as we would have when we extend PolymerTemplate?

We already tried to extend PolymerTemplate but we ran into problems with the required validation (as we have to check 27 languages instead of only the textfield value)

Best regards,
