Roland_D Posted January 15, 2013 Share Posted January 15, 2013 Hello guys I've been trying to solve this for a while now I have this: <ul id="0" class="nestedsortable"> <li id="29"> <div class="itemrow">Home</div> <ul id="29"> </ul> </li> <li id="37"> <div class="itemrow">Page 1</div> <ul id="37"> <li id="30"> <div class="itemrow">Page 3</div> <ul id="30"></ul> </li> </ul> </li> <li id="36"> <div class="itemrow">Page 2</div> <ul id="36"></ul> </li> <li id="31"> <div class="itemrow">Page 4</div> <ul id="31"></ul> </li> </ul> And I'd like to get this: $item[0][0]=29; $item[0][1]=37; $item[0][2]=36; $item[0][3]=31; $item[37][0]=30; So the bottom line here is I have a nested unordered list that is treated almost like an XML... now I need to collect the ID's of each LI in an ordered fashion and group them by UL ID's... Now, does it make any sense? Probably the fact that is nested has nothing to do with the process cause each UL has it's own ID but the UL's are contained into the LI's... Any help is appreciated!
