Solved. The following code works:

Edited widget_links function in widgets.php version 1.0.20060711

Tested on WordPress 2.0.7

function widget_links($args) {
extract($args);
global $wpdb;
?>

<?php
echo “$before_widget”;
echo “< ul >”;

// Loop through all link categories
$link_cats = $wpdb->get_results(“SELECT cat_id, cat_name FROM $wpdb->linkcategories”);
foreach ($link_cats as $link_cat) {

// Set current link category id
$cat_id = $link_cat->cat_id;

// Create a new

• element in the list of link categories.
  echo ‘< li id=”linkcat-‘.$cat_id.'”>’;

// This new list element begins with a title
echo $before_title;
echo ”.$link_cat->cat_name.’ ‘;

// and the expand/collapse link
echo function_exists(‘JSTB_box_toggle’)? JSTB_box_toggle(‘[+/-]’, ‘toggle’, ‘Click to toggle’, ‘cookie_link_’.$cat_id, ‘toggle_link_’.$cat_id) :”;
echo $after_title;

// followed by a list of links
echo ‘< ul id=”toggle_link_’.$cat_id.'” class=”JSTB_shown”>’;
wp_get_links($link_cat->cat_id);
echo “< /ul >”;

// Initialize
echo function_exists(‘JSTB_box_init’)? JSTB_box_init(‘cookie_link_’.$cat_id, ‘JSTB_shown’, ‘toggle_link_’.$cat_id) :”;
// and this particular category of links is done
echo “< /li >”;

// Next round in loop begins
}

// All link categories done.
echo “< /ul >”;
echo “$after_widget”;
?>

<?php
}

Note: In the code above, I have inserted some spaces inside the UL and LI tags, so that they would display as plain code.
