Inline if statement in grails

Is there a way in Grails to do condi开发者_如何学编程tionals inline on an HTML attribute, for example:

<div class="${if(sec.isLoggedIn()) loggedInClass}">

I'm trying to add a class to certain elements if the user is logged in.

This might work for you:

<div class="${(sec.isLoggedIn()?loggedInClass:null)}">

Or Try this:

<div class="${(sec.isLoggedIn()?'loggedInClass':'null')}">

You can do:

<div class="${sec.loggedIn ? 'loggedInClass' : ''}">
