HTML 4.01 says of the size attribute of the SELECT tag, Section 17.6, [ http://www.w3.org/TR/html401/interact/forms.html#h-17.6 ],
*size = <http://www.w3.org/TR/html401/types.html#type-number>*number* [CN] **If a SELECT <http://www.w3.org/TR/html401/interact/forms.html#edef-SELECT>element is presented as a scrolled list box, this attribute specifies the number of rows in the list that should be visible at the same time. Visual user agents are not required to present a SELECT element as a list box; they may use any other mechanism, such as a drop-down menu**. * The problem is, some user agents such as Firefox 3 display any SELECT with a size as a list box. This is a problem because according to the tag reference for h:selectOneMenu [ http://www.w3.org/TR/html401/interact/forms.html#h-17.6 ], *The SelectOneMenu tag renders an HTML "select" element with a "size" of 1 without the "multiple" attribute. This component is designed for situations where you want to display a single-select list of options to the user in a menu that displays one item at a time.* So it is impossible to create a SELECT tag without a SIZE element in JSF. Thus, it is impossible to create a drop down list / combo-box in HTML via JSF on Firefox 3. I know of no work-arounds to coax out a combo/ drop down behavior out of a h:selectOneMenu. I believe this is a defect in the JSF spec, and I would appreciate any workarounds anyone could offer.
