Reposition an anchored object on the page manually
Moving
a frame moves its anchored objects, unless the object is positioned relative
to margins or pages.
Note: Before moving an anchored object, make
sure that you deselect the Prevent Manual Positioning option for
the object in the Anchored Objects dialog box or choose Object >
Unlock Position.
Do
one of the following:-
To move inline anchored objects, use the Selection tool
or
Direct Selection tool 
to
select the object, and then drag vertically. You can move inline objects
vertically only, not horizontally. 
If you want
to move an inline or above line object outside of the text frame, convert
it to a custom-positioned object and then move it as desired. -
To move an inline anchored object parallel to the baseline, place the insertion point before or after the object and specify a new value for kerning.
If you want
to move an inline or above line object outside of the text frame, convert
it to a custom-positioned object and then move it as desired. -
To move custom-positioned anchored objects, use the Selection tool
or Direct
Selection tool to
select the object, and then drag vertically or horizontally.
