With SetHtml you just provide the parent element ID and the NodeSeq
you want to render as a child of that parent. You're saying you don;t
have the NodeSeq Corresponding to the List but I assume you do have
the list right? So assume this Ajax function:
def myCallback(): JsCmd = {
val myList = ...
val html: NodeSeq = myList.flatMap(e => <td>{e toString}</td>)
SetHtml("all_todos", html)
}
and then in your markup you can just have:
<div id="all_todos"></div>
If you were referring to something else, please provide more details.
