Hello, from the Phoenix.HTML.Form — Phoenix.HTML v4.3.0 docs, it looks like you can use it with a Map:

With map data
form_for/4 expects as first argument any data structure that implements the Phoenix.HTML.FormData protocol. By default, Phoenix.HTML implements this protocol for Map.

This is useful when you are creating forms that are not backed by any kind of data layer. Let’s assume that we’re submitting a form to the :new action in the FooController:

<%= form_for @conn.params, Routes.foo_path(@conn, :new), fn f -> %>
  <%= text_input f, :contents %>
  <%= submit "Search" %>
<% end %>
