hello, How do I retrieve an entire sublist if it any item in the sublist contains an item? I want the entire sublist filtered out if the bool mask contains true in any of the sublist line items. Thanks! ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/5/850259ea8c8241ac1a4ff26d039620e20e16c8b7.png) ---

You want List.ContainsItem in this case. It will check an entire list (or sublist) for an item. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/3/b3079dada3b20e6a8020cf5d73eadc8a7d481292.png) ---

feed your bool list through a LIST.ANYTRUE node or LIST. ALL FALSE @lvl2, can’t rememeber the package. then pick the sublist by index of true from the returned list. ---

Wait, that messes up my list structure and retriving all indices of true doenst work. What am I doing wrong? ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/2/429abfeb39d7edbfa04c36b44d5357c3a5cf7203.png) ---

Does the object your looking for equal “Warning” exactly? Can you show one of the warning objects in the list you’re filtering through? ---

You have to look for the exact item. ---

Well I do want “Warning”, but I want it as any word in any line in any index of any sublist. It may not be alone in the string ---

Then you’ll have to use the method @slepagetrudeau proposed. Find any item that contains warning, then use either of those nodes mentioned, or List.ContainsItem, to find sublists that contain True. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/f/df94a62ee09ca4e8595b8de3642592b335c23b65.png) ---

Ok yeah that works better ---

just a quick question on this, why do I have to set the list.allfalse @ lvl2? I thought that if you didnt run a node at levels, it defaulted to level 2. So why change it? Thanks ---

Oh, it might. I’am a control freak. No other reason than to be clear. As long as it works I don’t bother it. ---
