thanku for the reply
here iam using asp.net adrotator control for the image,

i tried the following

in dnn.controls.dnnmenu.js i adjusted  left and top of the menu as below.
menu.style.top=iNewTop-100+'px';menu.style.left=iNewLeft-20+'px'

now the submenu is coming right but the module menu is also getting changed.

and  i also tred this
in dnn.dom.positioning.js replaced line 42 with below
if ((eParent.id == (srcId || style.position != 'relative')) && (eParent.tagName.toUpperCase() != "BODY"))
{oPos.t+=eParent.offsetTop;oPos.l+=eParent.offsetLeft;}} 

now the module menu is going to the top of the page

the problem is module menu is also getting affected with the main menu.

how can i resolve this issue someone please suggest me.

thankyou
