How do I make a dynamic navbar LiveView that is on every page?

Look into putting in the live.html.heex like they do in live beats. I recently tried every which way of doing it and settled in doing it in the same fashion. With on_mount hooks it is clean.

Your options are: a sticky live view, a non sticky live view, a live component or function component you include on every page, or in the template.

<div
  id="mobile-sidebar-container"
  class="fixed inset-0 flex z-40 lg:hidden"
  aria-modal="true"
  style="display: none;"
  role="region"
>
  <div class="fixed inset-0 bg-gray-600 bg-opacity-75" phx-click={hide_mobile_sidebar()}></div>

  <div
    id="mobile-sidebar"
    class="relative flex-1 flex flex-col max-w-xs w-full pt-5 pb-4 bg-white hidden min-h-screen"
  >
    <div class="absolute top-0 right-0 -mr-12 pt-2">
      <button
        type="button"
        id="hide-mobile-sidebar"
        aria-expanded="true"
        aria-controls="mobile-sidebar"
        class="ml-1 flex items-center justify-center h-10 w-10 rounded-full focus:outline-none focus:ring-2 focus:ring-inset focus:ring-white"
