    Is the Content Navigation supposed to expand and collapse all of the levels each time you go to a new page? I have a course with a lot of pages and it really slows down the process of moving from one page to the next.

    Thanks, Sandie

    Re: Content Navigation expand/collapse

    Yes, it's the current behaviour of the content navigation which gets re-loaded each time when page reloads. It does slow down the page load quite a bit when the content levels are many or deep. We've realized the issue and had it on the to-do list. Sorry about this.

    Re: Content Navigation expand/collapse

    Any idea when it might be fixed? I am hoping to upgrade my production site within the week but would prefer to do it after this is fixed.

    Thanks,

    Sandie

    It won't be in the upcoming release which is coming before the christmas. Hopefully it would make into the next release at mid-2011.

    FYI, this doesn't happen in the version of 2.0.1 that I installed on another webhost a few weeks ago. I just downloaded and installed the problematic version last week.

    Re: Content Navigation expand/collapse

    Interesting. 2.0.1 is the latest version. Which version you have problem with?

    Re: Content Navigation expand/collapse

    Both sites are running version 2.0.1.

    Here's the info for the site on hostmonster at www.hpc-training.org/ATutor/ that was installed a few weeks ago and is not having the problem:

    You can login as a student on either site using the login/pw of guest/student . Choosing the 'Introduction to MPI' course gives an example of a content navigation with many levels.

    The Intro to MPI course uses a slightly modified version of the ATutor default theme. I have also tested it with the default theme on both sites with the same problem.

    Re: Content Navigation expand/collapse

    Oops, I typed the URL to one of the sites wrong. It should be www.citutor.org/atutor/ rather than www.cituor.org/atutor/ .

    Re: Content Navigation expand/collapse

    Thanks. Have figured the url out.

    I tried both sites and they don't seem to have the significant time difference while switching between content pages. Is www.citutor.org/atutor/ the one you feel much slower than the other?

    Re: Content Navigation expand/collapse

    Yes, that is the slower one. It isn't as easy to notice since I added a scroll and set a max height to the content navigation box in my theme but the navigation structure expands and collapses before displaying the page content on the www.citutor.org/atutor site where it does not on the other one.

    Re: Content Navigation expand/collapse

    There is a slight difference in the ContentManager.class.php file on my two sites that addresses how the content folder is displayed. I copied the one from the site that works the best to the other site and the expand collapse problem is fixed.

    Here's the code from the one that works best:

    $result = mysql_query($sql, $this->db);
    // print out javascript to expand the first content folder
    if (mysql_num_rows($result)) {
    $row = mysql_fetch_assoc($result);
    echo $this->get_js_expand_folder($row['content_id']);
    }

    Here's the code from the one that is buggy (expands and collapses):

    $row = mysql_fetch_assoc($result);

    // print out javascript to expand the first content folder
    echo $this->get_js_expand_folder($row['content_id']);

    Re: Content Navigation expand/collapse

    I see. That's a bug in 2.0.1. You don't have to manually modify the script. Applying Patch#1 would fix it.

    How to apply a patch:
