Hi,
Enhance method do_prepare_output and change the selection mode
method DO_INIT_CONTEXT.
* set initial selection mode for all tables
typed_context->context_node_name->set_selection_mode(
IV_SELECTION_MODE = CL_BSP_WD_CONTEXT_NODE_TV=>SELMODE_MULTI
).
endmethod.
else change it .htm page tag configTable attribute "selectionMode" = 'MULTISELECT'

Deepika.
