hi i am using datepicker which works fine if there is one date field.
I am generating dynamic date fields using jquery. But datepicker does not work on those dynamic fields.

Does anyone have a tutorial/example that shows how datepicker is used with dynamic form elements?

<< each time you create a new datepicker >> mean after creating the new datepickers NOT BEFORE! And use the right ID :)

I dont understand what you are trying to say.

Before/after does it matter?  they are within the script tag.

ID's are right - for the first field field id will be datepicker1 for susbsequent fields generated dynamically IDs will be datepickerNUMBER so that is datepicker2..datepicker3...so on

Yes it is ! This is you issue, run datepicker AFTER each dynamically generated input dedicated for your datepicker
