Summary
Tag name:
<tr:selectItem>
UIComponent class:
org.apache.myfaces.trinidad.component.core.input.CoreSelectItem
Component type:
org.apache.myfaces.trinidad.CoreSelectItem
The selectItem tag represents a single item that the user
may select from a list, choice, radio, or shuttle Trinidad control.
It may be used in place of the JSF selectItem or selectItems
tags, but is very similar (largely not requiring "item" in front
of its attributes.)
Example(s):
<tr:selectOneRadio value="#{bean.aValue}" required="true"> <tr:selectItem label="Option1" value="1"/> <tr:selectItem label="Option1" value="2"/> <tr:selectItem label="Option1" value="3"/> </tr:selectOneRadio>
