Strangely enough, this does not seem to be the case. You apparently
need to use several explicit ui:ifvar. See ui:cond:

The main issue is that "select" is related to the <select> HTML tag
that is interpreted by the web browser and handled correctly when the
FORM is submitted. You cannot substitute a <select> tag with any tag
if you want the browser the interpret the selection correctly.

However, we might try to solve the issue on the Caml side. When the
list is build, we might introduce carriage returns in each "select"
entry in order to limit each line size to, say, 80 columns. We might
reuse the routine used in the GTK+ client (lib/Misc.add_line_splits).

The only issue is that I don't know how carriage returns are
interpreted by web browsers.

Yours,
