dropdowns and checkboxes make the map shift up

[RobertKirkwood]

when the application is viewed at 1024 x 600 for example,  the dropdown menus and check boxes (when selected) cause the map to shift up. here is a link to the application:

I know this has something to do with CSS but cannot figure out why ow what is causing the problem. Anyone have any ideas? Thanks ahead of time!

Not sure whats causing the problem. I find that the map is not actually shifting but the banner image is being moved. just a couple of suggestions. Try to have the map also inside a contentpane with region set to center
or

set the top of the map top to 35px so that map does not overlap the title.

orsee if reordering the elements in the html helps. i.e. move the map div after the other divs

Hope it helps.

I made the Banner "fixed" position in the CSS and that corrected the problem
