Hey, as if I get many users on my app it will fast become a mess. I so need to make sublists on Firebase. After playing a bit with json and else, I succeeded in creating the following : ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/5/a54bbcf18adfd3303d4f5cf10a098ba704bb0cb2.png) Which gives : ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/7/97fa241f03d63bf8f936356669dba69870bc51bb.png) But my question now is : How do I get to modify the sublist items ? Could you please directly share the blocks I need ? Here is the demo project : [https://x.thunkable.com/projects/5baa9bb71149e023913113fe/Screen1/blocks](https://x.thunkable.com/projects/5baa9bb71149e023913113fe/Screen1/blocks) Thanks ! ---

Hey @Mark ! I think this block is the solution I’m searching for ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/d/8dee24428ca2bf4c4b9afeba7132a6a74e653856.png) but sadly when I try to insert it it shows me this ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/2/821ff3808ad63aa70fa6448cc9c1133688a1ffb8.png) Is this a known issue ? And if yes, do you know any workarounds ? Thank you ! ---

I don’t get the idea I’m sorry I’m totally new to this. You’re telling me to recreate the list everytime with the create object block ? ---

First, I tell you that “root/test” is definitely not a JSON and because of that you cannot use the get-object-from-JSON block here. “{}” is an empty object. Please create objects with the rosa components and then use the get-JSON-from-object blocks and look at the output (maybe assign these blocks to a label. then you will learn it and understand ---

Hey @User81 ! After all this I think blocks would be the greatest option or even a simple project if you have a bit of time, I’ll share the final result when I’ll find it. Thanks ! 🙂 ---

I generally recomment to NOT use the rose blocks with the realtime DB. instead use in Realtime\_DB1 call Save key= “root/test” value = “mdr” [Next page](https://community.thunkable.com/t/modify-data-in-realtimedb/51947.md?page=2)
