I've created a Partial View Macro - it's pretty basic - it just creates a special link - or it would do if it worked.

My file is in Views/MacroPartials/BlackButton.cshtml and the contents are below:

@inherits Umbraco.Web.Macros.PartialViewMacroPage
<a href="#" role="button" class="leftbutton">Black button</a>

However this renders out on the page like this:

Macro alias: BlackButton

I've experimented with different content in the BlackButton.cshtml file and if I change the HTML to just be:

<div>some text</div>

then it works.

So there seems to be a problem with certain tags (it doesn't like anchors or the old b tag) or certain attributes (data-*, in this case that "role" one).

Does anyone know why this is happening? Is there a list somewhere of allowed tags and attributes? Is there a way of disabling this?

I'm also open to suggestions if there is a better way of inserting HTML snippets like this.

Thanks in advance for any help.
