Hi Sumit,
I think that will be available in VIEW_AREA variable of the IMPL Class of an overview page.
I also checked the GO TO Feature in CRM and it works with Javascript and Ajax.
Below code generates the script with Item list as assignment blocks for Go To button.
lr_menu = cl_thtmlb_dynamenu=>factory(
ajaxhandlerclass = me->ajaxhandlerclass
design = me->menudesign
for = lv_parent_id
id = lv_menu_id
items = lt_items
position = me->menuposition
* ??? = me->submenuLoadOnDemand Possible future development.
trigger = me->trigger
onbeforeopen = lv_onbeforeopen
onafterclose = 'th_mb_close'
switchid = me->switchid ).
you can debug in method IF_BSP_ELEMENT~DO_AT_BEGINNING of class : CL_THTMLB_MENUBUTTON
Search for lv_onbeforeopen = me->onclientclick. and read the comments by SAP.
Regards,
Naresh
