<p:panel id="sports" header="<p:inputText id='headerz' value='text of headerz'" toggleable="true" closable="true" >
this is my code. Page doesnt show p:inputText. on the source code of page i can see the input text with id=headerz but it is greyed.
Try This:
<p:panel id="sports" toggleable="true" closable="true" >
<f:facet name="header">
<p:inputText id='headerz' value='text of headerz' />
</f:facet>
</p:panel>
