Thanks Jeppe, that looks like what I need.
I'm having trouble following your example though, what are res,
filteredResult, lc, etc? My code looks like this right now:
def render( xhtml: NodeSeq ): NodeSeq {
items.flatMap( f =>
bind("item", xhtml,
"name" -> item.name
)
}
so presumably I'd need to add to that to bind an attribute called
value:
def render( xhtml: NodeSeq ): NodeSeq {
items.flatMap( f =>
bind("item", xhtml,
"name" -> item.name,
AttrBindParam("value", item.value)
)
}
