Hi LAS,
Everything is possible. I am providing the logic here which will help you a lot.
For insert, Change, Delete: 
   Just get the all the elements into temp internal table and get the lead slected index. Now instrt one row in the lead selected index position. then again bind the temporary internal table to your table node. Thats all it works like inserting the row.
In the same way you can do the change and delete rows also.
For Dropdown:
  Here i am providing the code for Dropdown. It will help you out.
  Just create the Dropdown view for the columns for which you want dropdown. And do the coding for that.
  Here in my scenario IT is the Table node which holds the information. And i am providing the dorpdown key for the column "BSCHL".
  If you have any dobts just reply to me . i will respond it.
Code:
  data : ls_outtab               type /kyk/s_fb01_line,
         lt_outtab               type table of /kyk/s_fb01_line,
         lv_node_sd              type ref to if_wd_context_node,
         lv_node_it              type ref to if_wd_context_node,
         lv_node_info            type ref to if_wd_context_node_info,
         lv_node_sapmf05a_0106   type ref to if_wd_context_node,
         lv_node_waers           type ref to if_wd_context_node,
         lv_node_layout          type ref to if_wd_context_node,
         lv_rowcount             type i,
         lv_buzei                type i,
         lv_waers        type waers,
         lt_bschl_set    type wdy_key_value_table,
         bschl_key_item  type wdy_key_value.
bind to context
  lv_node_sd      = wd_context->get_child_node( name = 'SD' ).
  lv_node_it      = lv_node_sd->get_child_node( name = 'IT' ).
  call method lv_node_it->bind_table
    EXPORTING
      new_items = lt_outtab.
fill Dropdown Help for posting Key
  bschl_key_item-key    = '40'.
  bschl_key_item-value  = cl_wd_utilities=>get_otr_text_by_alias( '/KYK/FIN_FI/DEBIT_GL_ACCOUNT' ).
  insert bschl_key_item into table lt_bschl_set.
  bschl_key_item-key    = '50'.
  bschl_key_item-value  = cl_wd_utilities=>get_otr_text_by_alias( '/KYK/FIN_FI/CREDIT_GL_ACCOUNT' ).
  insert bschl_key_item into table lt_bschl_set.
  bschl_key_item-key    = '21'.
  bschl_key_item-value  = cl_wd_utilities=>get_otr_text_by_alias( '/KYK/FIN_FI/DEBITVENDOR' ).
  insert bschl_key_item into table lt_bschl_set.
  bschl_key_item-key    = '31'.
  bschl_key_item-value  = cl_wd_utilities=>get_otr_text_by_alias( '/KYK/FIN_FI/CREDITVENDOR' ).
  insert bschl_key_item into table lt_bschl_set.
  lv_node_info = lv_node_it->get_node_info( ).
  lv_node_info->set_attribute_value_set( name = 'BSCHL' value_set = lt_bschl_set ).
