As specified in its TLDDOC, just set the size attribute accordingly. It denotes the number of options shown at once. If not specified, then all options will be shown at once.

If you want to show 1 option while the fictive boolean expression #{bean.readonly} returns true, then you can make use of the ternary operator expr ? doThisIfTrue : orDoThisIfFalse in EL:

<h:selectManyListbox size="#{bean.readonly ? '1' : ''}">
