Try:
<lift:foo.myFoos>
<foos:list>
<div foo:div_id="xxx">
<foo:id/>
</div>
</foos:list>
</lift:foo.myFoos>
In your bind:
def doFoo(in: NodeSeq): NodeSeq = List("a", "b", "c").zipWithIndex.flatMap {
case (str, idx) =>
bind("foo", "id" -> str, AttrBindParam("div_id", Text("my_foo_"+idx),
"id))
}
bind("foos", xhtml,
"list" -> doFoo _)
The AttrBindParam will bind to an attribute and let you create a value and a
new name for the attribute.
Does this help?
