It would be helpful to have the ability to enable/disable certain accordion panes. For example, disable a pane until an ajax request has completed loading the content contained within.

This could be implemented in the clickHandler by checking a html attribute in the header before opening the pane:

// If header is disabled then ignore click
if(clicked.attr('disable') == 'True') {
    return false;
}

Also, to allow javascript manipulation, write enable and disable functions which would add or remove the disabled attribute to the header specified by an index.
