 * I’m stuck. I can’t find this ul tag inside the php, you can see from the error
   it’s missing a qoute for the id.
 *     ```
       Line 446, Column 47: an attribute value specification must be an attribute value literal unless SHORTTAG YES is specified
       <h2 class="widgettitle">Categories</h2><ul id=widget-collapscat-2-collapsCatList>
       ```
   
 * Could anyone show me where can i add the qoutes back (“” or ”), thanks.

 * It seems to be causing several validation problems for me too.

 * collapscatwidget.php line 19
 *     ```
       echo "<ul id=" .  $this->get_field_id('collapsCatList') . ">\n";
       ```
   
 * Change to
 *     ```
       echo "<ul id=\"" .  $this->get_field_id('collapsCatList') . "\">\n";
       ```

 * Here is my workaround for the remaining issues (not compatible with multiple 
   widget instances):
 * in collapscatwidget.php
 *  Delete lines 19 & 25.
 * in collapscatlist.php
 *  at line 307 (after defaults.php) add
 *     ```
       echo "\n<ul id=\"collapsCatList\">\n";
       ```
   
 *  at line 614 …
 *     ```
       //  echo "    </ul> <!-- ending collapsCat -->\n";
       ```
   
 *  … change to
 *     ```
       echo "    </ul> <!-- ending collapsCat -->\n";
       ```
   
 * Front page is now valid.

 * Thanks a lot
    It works perfectly I’ve been searching for awhile with no result…
   And now it validates!
