There are several web browsers available for the iLiad, which has a touch screen so the drop down menu should not be a problem. If the web site is open to everyone, post its address and we can try it out for you. Normally, text (e.g. web addresses) are typed on the on-screen virtual keyboard using the stylus, but it is also possible to attach a real keyboard via USB.
Available browsers:
Minimo Installer for the iLiad (beta),
dillo web browser for the iliad and
elinks text-based web browser (like lynx). All are included in the
wiki software list.
