Table Tree with Webdynpro ABAP

Hello Gurus,

I have successfully implemented table tree up to 4 levels, which was previous requirement with the client. But now I need table tree with the multiple levels. Here we don't know that, up to how much level the tree will expand in the table. I have to configure out at the run time only.

Here I have taken the help of code with the following URL.

Now, I have searched the SDN, but didn't found any relevant solution.

Please help. Its urgent.

Thank you.
