This simple javascript anables you to dymanically create multiple objects (forms with datepicker). selector is the specific object you want to dynamically create, e.g for table rows <tr> call like so: cloneFormObject('.tr:last', 'gates');

Create Forms with datepicker Dynamically using javascript

function cloneFormObject(selector, prefix) {
    var currentElement =  $(selector)
    var formCount = parseInt($('#id_' + prefix + '-TOTAL_FORMS').val());
    $(currentElement).find('input.date_picker').datepicker({dateFormat:"M-dd-yy", minDate:0, autoclose:true});
    var newElement = $(currentElement).clone(true).get(0);

    $(newElement).removeAttr('id').insertAfter($(currentElement)).children('.hidden').removeClass('hidden');

    $(newElement).find(':input').each(function() {
        var name = $(this).attr('name').replace('-' + (formCount-1) + '-','-' + formCount + '-');
        var id = 'id_' + name;
        $(this).attr({'name': name, 'id': id}).val('').removeAttr('checked');
    });
    $(newElement).find('label').each(function() {
        var newFor = $(this).attr('for').replace('-' + (formCount-1) + '-','-' + formCount + '-');
        $(this).attr('for', newFor);
    });

    // MUST assigned new date picker at the end for new id!
    $(newElement).find('input.date_picker').attr("id", "")
        .removeClass('hasDatepicker').removeData('datepicker')
        .unbind().datepicker({dateFormat:"M-dd-yy", minDate:0, autoclose:true});

    $('#id_' + prefix + '-TOTAL_FORMS').val(formCount + 1);
    return false;
}

To clone say a formset with already made tools where you just want to add links for the client to click to either delete or create a formset_factory for example, use this: https://github.com/elo80ka/django-dynamic-formset/blob/master/docs/usage.rst
