jQuery UI: TypeError: $(...).accordion is not a function

For some reason the jQuery UI Accordion does not work. I keep getting this error:

TypeError: $(...).accordion is not a function

What am i doing wrong? Based on other answers on this site on similar topics, i think it has something to do with the included files.

My header includes are:

Solution

  • This problem could arise from a couple of different things:

    • You are not including jQuery UI library.
    • You are including jQuery UI library above the inclusion of jQuery library
    • The path to jQuery UI and jQuery libraries might be incorrect
    • You are using a custom jQuery UI library that does not have an accordion

    Since the first two do not apply to you, I would recommend triple-checking the path and using a full jQuery UI library instead of the custom one:

    <script src="http://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>
