Hi Rama,
what i am understood is to display the tree view attributes under nodes right in that case in your tree view there is method get_table_line_sample method add the required attributes and then go to .htm of the tree view click on page attributes under there is attribute type of your context node name (ex: tree type zcl_xx_xx_c01) check this if this is not your first context node class then replace that class then after simply move the fields from available to display using configuration.
if this not your requirement please provide screen short for better understanding..
Thanks & Regards,
Srinivas.
