Primefaces custom positioning for a specific p:growl

问题

I am using PrimeFaces 3.3.1. I can customize growls by:

.ui-growl {
    position:absolute;
    top:50%;
    left:50%;
    z-index:9999;
}

But it customizes all growls. I need to customize just one specific <p:growl>. I mean, I want to place just one growl to the center and all the rest to the top right corner. How to do that?

Thanks.

As you can see from the generated HTML the growl component isn't holding your actual growl data. The message which is appearing in the corner is hold by a div element:

<div id="your_growl_id + _container">

so the correct css selector for growl would be:

div[id="growlForm1:growlCenter_container"] {}

(I assume your growl components are placed into the same form). Finally as you noted in your post if you have two growl components on your page:

<h:form id="growlForm1">
    <p:growl id="growlCenter" showDetail="true" sticky="true" />
    <p:growl id="growlRight" showDetail="true" sticky="true" />  
</h:form>

just assign the desired css properties for the centered and not-centered growl containers:

div[id="growlForm1:growlRight_container"] {
    position:absolute;
    top:20px;
}
div[id="growlForm1:growlCenter_container"] {
    position:absolute;
    top:20px;
    left:40%;
}

Note that you can use the prependId="false" attribute of the <h:form/>. That would simplify the css selectors. But it is advised not to use this, see UIForm with prependId="false" breaks <f:ajax render>
