Produkt: Custom Elements Contao

I have a custom element the offers a list of all Contao News Headlines:
'foreignKey' => 'tl_news.headline',

Now I wold like to filter and show only news, that have an Podcast. ('tl_news.podcast').

As far as I understand, I should do alike with 'options_filter'.
Is that possible, and what would the code look like?

Thank you,
Martin

    Vielen Dank für Ihre Frage.

    Eine options_filter-Option ist uns nicht bekannt. Für eine gefilterte Liste können Sie den options_callback benutzen und den gewünschten SQL-Query darin selbst ausführen.
