// jQuery

function checkRemove() {
    if ($('div.container').length == 1) {
        $('#remove').hide();
    } else {
        $('#remove').show();
    }
};
$(document).ready(function() {
    checkRemove()
    $('#add').click(function() {
        $('div.container:last').after($('div.container:first').clone());
        checkRemove();
    });
    $('#remove').click(function() {
        $('div.container:last').remove();
        checkRemove();
    });
});

Below code to attach remove button against each group.

$(document).ready(function() {
    var removeButton = "";
    $('#add').click(function() {
        $('div.container:last').after($('div.container:first').clone());
        $('div.container:last').append(removeButton);

    });
    $('#remove').live('click', function() {
        $(this).closest('div.container').remove();
    });
});
