Question: I'm using twitter bootstrap with grails and have the following in my layout:

```
        <div class="nav-collapse">
            <ul class="nav">
                <li><a href="${createLink(uri: '/request/new')}">My Link</a></li>
            </ul>
        </div>

```

On my page I have the following:

```
<html>
    <head>
        <meta name="layout" content="bootstrap">
    </head>

    <body>
        sometext
    </body>
</html>

```

**Question**

In my layout how do I detect when the `My Link` action is clicked? so that I can highlight it using `class="active"`

Answer: 
Here is how I tend to do this.

First, in your layout, you would do something like this:

```
<div class="nav-collapse">
    <ul class="nav">
        <li class="${ pageProperty(name:'meta.nav').equals( 'foo' ) ? 'active' : null }"><a href="${createLink(uri: '/request/new')}">My Link</a></li>
    </ul>
</div>

```

And in your page:

```
<html>
    <head>
        <meta name="layout" content="bootstrap">
        <meta name="nav" content="foo"/>
    </head>

    <body>
        sometext
    </body>
</html>

```

`foo` is the trigger to apply the `.active` class.
This should work (notice it's slightly different to Isammoc's answer)

```
<li class="${controllerName == 'user' && actionName == 'profile' ? 'active' : ''}"> profile </li>

```
