If the user selects an option in a dropdown box, there must be added a label and a textbox. Using appendChild, these elements get added to the end of the container.

var newFreeformLabel = document.createElement('label');

newFreeformLabel.innerHTML = 'Omschrijving:';



var newFreeformField = document.createElement('input');

newFreeformField.className = 'textfield';

newFreeformField.name = 'factuur_orderregel[]';



var newFreeformSpacer = document.createElement('div');

newFreeformSpacer.className = 'spacer';



container.appendChild(newFreeformLabel);

container.appendChild(newFreeformField);

container.appendChild(newFreeformSpacer);

The issue is that these elements should be inserted at the beginning of container, not at the end.

Is there a solution to this in PrototypeJS?
