I am trying to implement a slide down for table rows using the previous post here
I have a newrole table where I click on add icon and it gets added to rolecart table with 3 rows for each item. First row is copied as it is from the role table the next 2 rows are added using jQuery, below is the code.
$("#table_newrole img.move-row").live("click", function() {
    var tr = $(this).closest("tr").remove().clone(); 
    tr.find("img.move-row")
        .attr("src", "/gra/images/icons/fugue/cross-circle.png")
        .attr("alt", "Remove");
    // first row copied from the source table as it is
    $("#table_rolecart tbody").append(tr); 
    // next two rows added like this
    var $inputtr = $('<tr><td colspan="3">Business Justification:  <input type="text" id="ar_businessjust"></td></tr><tr><td colspan="2">Start Date: <input type="text" id="ar_startdate"></td> <td colspan="1">End Date: <input type="text" id="ar_enddate"></td></tr>');
    $("#table_rolecart tbody").append($inputtr);
});
When I add next item to the cart I want the previous item's last 2 rows to slide up (I will later provide and icon to slide down to show these rows)
Need to know how to implement this. more specifically I need to know how do I select previous cart items last 2 rows and then apply the slideup to the divs.
