E0108: No such ref or attribute value

A JS command names an element by ref (ui.Ref("menu")), or an attribute value (ui.GetAttr("type", "email")), that the component's markup doesn't have. The message lists what there is, or suggests the nearest name.

Wrong

func Menu() ui.Node {
	return <nav>
		<ul ref="menu">…</ul>
		<button onClick={ui.JS.Toggle(ui.Ref("mnu"))}>Menu</button>
	</nav>
}

Right

func Menu() ui.Node {
	return <nav>
		<ul ref="menu">…</ul>
		<button onClick={ui.JS.Toggle(ui.Ref("menu"))}>Menu</button>
	</nav>
}
