I also tried to add a form for each element from the list like this:

<div :if={assigns[:"form_#{rv.id}"} class="mt-8 ml-12">
  <.simple_form for={assigns[:"form_#{rv.id}"]} id="reply_review_form" phx-submit="submit_reply" class="mb-6">
      <:actions>
          <.input type="hidden" id="review_id" field={assigns[:"form_#{rv.id}"][:review_id]} />
      </:actions>
      <:actions>
          <label for="comment" class="sr-only">Your comment</label>
          <.input type="textarea" id="comment" field={assigns[:"form_#{rv.id}"][:content]} rows="6"  placeholder={gettext("Tell us...")} />
      </:actions>
      <:actions>
        <button type="button" phx-click="cancel_reply">
          <%= gettext("Cancel") %>
        </button>
        <button type="submit" >
          <%= gettext("Send") %>
        </button>
      </:actions>
    </.simple_form>
  </div>

and

def handle_event("show_reply_form", %{"id" => review_id}, socket) do
    form_data = %{
      "review_id" => review_id,
      "content" => nil
    }
    form = to_form(form_data, as: "review")
    socket = assign(socket, "form_#{review_id}": form)
    {:noreply, socket}
  end

Theoretically it should render just the form from the corresponding review but nothing is send to UI.
