title: How to use jQuery's "slideDown" and "slideUp" effect in the jQuery Expander Plug-in?
body: <p>I'm using the <a href="http://plugins.learningjquery.com/expander/index.html#options" rel="nofollow">jQuery Expander</a> plug-in. I would like it to use an effect like jQuery's slideUp and slideDown as opposed to the default, fadeIn.</p>
  
  <p>Can someone tell me how to do this?</p>
  
  <p>Here are the default options:</p>
  
  <pre><code>$.fn.expander.defaults = {
    slicePoint:       100,      // the number of characters at which the contents will be sliced into two parts. 
                                // Note: any tag names in the HTML that appear inside the sliced element before 
                                // the slicePoint will be counted along with the text characters.
    widow:            4,        // a threshold of sorts for whether to initially hide/collapse part of the element's contents. 
                                // If after slicing the contents in two there are fewer words in the second part than 
                                // the value set by widow, we won't bother hiding/collapsing anything.
    expandText:       'read more...',   // text displayed in a link instead of the hidden part of the element. 
                                // clicking this will expand/show the hidden/collapsed text
    expandPrefix:     '… ', // text to come before the expand link                              
    collapseTimer:    0,        // number of milliseconds after text has been expanded at which to collapse the text again
    expandEffect:     'fadeIn',
    expandSpeed:      '',       // speed in milliseconds of the animation effect for expanding the text
    userCollapse:     true,     // allow the user to re-collapse the expanded text.
    userCollapseText: '[collapse expanded text]',  // text to use for the link to re-collapse the text
    userCollapsePrefix: ' ', // text to come before the re-collapse link
    beforeExpand: function($thisEl) {}, // function that is called immediately upon expanding, before the expand occurs
    afterExpand: function($thisEl) {}, // function that is called after the details have finished expanding
    onCollapse: function($thisEl, byUser) {} //function that is called when the details are collapsed (immediately after)
  
  };
  </code></pre>
