A single, stackable modal container for Phoenix LiveView.

One stack per page (only one modal is visible at a time). State lives in socket.assigns.modal_stack as a %ModalStack{} struct; there is no live_component and no hidden process.

Setup

def mount(_params, _session, socket) do
  {:ok, ModalStack.attach(socket)}
end

Opening / closing (from your event handlers)

ModalStack.push(socket, :confirm_delete)
ModalStack.pop(socket)
ModalStack.clear(socket)

Rendering

<ModalStack.modal_stack stack={@modal_stack}>
  <:modal name={:confirm_delete} on_cancel={JS.push("delete_cancelled")}>
    ...body...
  </:modal>
</ModalStack.modal_stack>

The close button, Escape, and click-away automatically pop the stack via a hook attach/1 installs — you do not write a close handler. A slot on_cancel (optional) runs as an extra side-effect alongside the pop.
