Question

I have datatable with multiple checkbox selection (PF 3.3.1). I’ve defined column:

<p:column selectionMode="multiple"/>

I would like add some text or icon to header and I tried with headerText column attribute and with facet:

<f:facet name="header">
    <h:outputText value="Header text" />
</f:facet>

But it doesn’t work.
It is possible to modify header of checkbox selection column?

Answer 1

In case you want that feature badly and don’t mind to use jquery, You could do something like

I tested it on primefaces shocase and it works (run these command at the console)

$("<span class='someClass'>Hellow</span>").insertAfter($('#form\\:multiCars thead tr:eq(2) th').find('.ui-chkbox-box'))

note that #form\\:multiCars should be changed with your table id

and tr:eq(2) refers to the third row in the table , cause in showcase the row with the headers is third

to change the width of that selection column you can use

$($('#form\\:multiCars thead tr:eq(2) th')[0]).css('width',100)

I’m aware of the fact that its waaaay ugly , but it works 🙂

Also you will have to run this script after each ajax rendering of the table
