Thats a cool idea.
Good thinking :-)
Furthermore if there really is little space you could set the size to 1.
Then all the errors could be rendered as options and the user would just
need to click the select to drop down the list for reading.

Subject: RE: <html:errors/> question


How 'bout using a dummy form with a select element whose size attribute is
3?
Each error message would be rendered as an option element. Of course,
there's no
strict requirement for browsers to render a select element as a scrollable
list
box when the size attribute is present (and > 1), but IE 6.0, NS 4.79, and
Mozilla 1.2 seem to do so.

<form>
  <select size="3">
    <option>Error 1</option>
    <option>Error 2</option>
    <option>Error 3</option>
    <option>Error 4</option>
    <option>Error 5</option>
    <option>Error 6</option>
  </select>
</form>
