render block list recursively
How do i render a block list recursively.

For example i'm using a block list in my footer, which is want to render on all pages...
```
@Html.GetBlockListHtml(Model, "sidefod", fallback: Fallback.ToAncestors)   
```
Doesn't work

Do it like this my friend:

@inherits Umbraco.Web.Mvc.UmbracoViewPage
@{
    Layout = null;
    var node = Model.AncestorOrSelf();
}

<div>@Html.GetBlockListHtml(node, "footer") </div>

That should work, but doesnt in my case, so i did:

@inherits Umbraco.Web.Mvc.UmbracoViewPage
@{
    Layout = null;
    var rootnode = Model.Root();
}

<div>@Html.GetBlockListHtml(rootnode, "footer") </div>

Glad you got it working, but can't you just do it like with any other property?
```
Html.GetBlockListHtml(node, "footer", recurse:true)
```

Dont think so:

"The best overload for 'GetBlockListHtml' does not have a parameter named 'recurse'"

The solution works if you want to grab a Block List from the root node, or a parent, but doesn't give a full Fallback.ToAncestors functionality.

A better solution for full recursive block list rendering is to Set the BlocklistModel object recursively, then pass that object into Html.GetBlockListHtml()

Example
```
@{
    var blocks = Model.Value<BlockListModel>("blocks", fallback: Fallback.ToAncestors);
}

@Html.GetBlockListHtml(blocks)
```
