Question

I want to create a Class, say MyDiv, which inherits from the original DOM DIV element.
Later in my code I would like to use it like that:

$('a-container').adopt(new MyDiv('my own set of params'));

I am missing the exact syntax to do it.

You don’t necessarily need to extend a specific Element type. If you provide a toElement method, you can define what’ll be adopted in such a case:

var MyDiv = new Class({
    initialize: function() {
        this.realDiv = new Element('div',{id:'foo'});
    },
    toElement: function() {
        return this.realDiv;
    }
});
