this is the s:selectItems for country field.....See here some of the country names are having more lenght...Those country names are not displaying fully....But it is working fine with mozilla....
This is my code-->>
h:selectOneMenu value="#{bookerDetailsSetup.bookerDetails.country}" style="width: 200px;">
<s:selectItems value="#{dictionaryUtils.retrieveDictionaryItems('Country', bookerDetailsSetup.bookerDetails.country)}" width="200px;" var="country" label="#{country.value}"/>
<s:convertEntity/>
</h:selectOneMenu>
