The following code expands Free Nodelet Hack: RAT collapse all in different aspects.

It checks if I'm surfing perlmonks with my (small screen) mobile (appName=="Obigo") and automatically collapses only root nodes of threads (nnt-depth-1).

A link in the "Free Nodelet" allows to toggle the folding.

This code is a blueprint for customizing appearance and UI in different browsers. The navigator object provides more attributes to distinguish browser and OS.

Suggestions welcomed! :)

<script language="javascript"><!--
 var expandState="expanded";
 function toggle_threads(){
    expandState  = (expandState=='expanded')
                       ? 'collapsed'
                       : 'expanded'
                       ;
    var elements = document.getElementsByTagName('ul');
    var elnum;
    for( elnum=0; elnum<elements.length; elnum++ ){
        var el = elements[elnum];
        if ( el.parentNode.className.match(/nnt-depth-1/) )
           el.className = expandState;
    }
 }
 
 if ( document.title=="Recently Active Threads" ) {
    document.writeln('<a href="javascript:toggle_threads()">+/- Thread
+s</a>');
    if (navigator.appName=="Obigo")
       toggle_threads();
 }
//--></script>

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
