I'm using the mobile jquery theme, and listboxes rendered on the left of the page expand to be partly off-screen.

For example, I have a option element with the numbers 1 to 10 in it. When clicked on it expands, centred on the location of the main element, but this means part of it is off-screen, in particular the parts containing the numbers, so none of the numbers are visible, just their containers! Of course it still works but this looks ridiculous on a mobile where it's not really possible to move the element further to the right.

Any ideas? Or maybe a workaround to make the numbers appear further to the right of their expanded boxes so they're visible again?

Thanks,
Ian.
