Preselected Dutch Banks

Hello,

I am using the gravity form with your iDeal plugin and created a form in an IFRAME. The form works well, but I would like to have the option that the ‘’banken uitschuifkeuzelijst’’ is already pre-selected at ABN AMRO.

This way customers can see that they need to select the appropriate bank by changing it.

Is this possible? And how can I achieve this?

Thank you!
