Since v7.0.10Signature
id()Generate an HTML id attribute value.
return the ‘<form>` element’s id attribute.
“‘ <%= form_with model: @article do |f| %>
<%# ... %>
<% content_for :sticky_footer do %>
<%= form.button(form: f.id) %>
<% end %><% end %> “‘
In the example above, the :sticky_footer content area will exist outside of the ‘<form>` element. By declaring the form HTML attribute, we hint to the browser that the generated `<button>` element should be treated as the `<form>` element’s submit button, regardless of where it exists in the DOM.
