title: Symfony 3 - menu without bundle
body: <p>I have big static main menu with only 3 items which I need load from database. These items have own children so they are in multidimensional array and each item need own select so 3x select = 3x multi array.</p>
  
  <p>I think I don't need any bundles because select this items is fast and easy. (+ it is project with non-standard db structure so implement bundle could be harder) </p>
  
  <p>But I am new in Symfony so my question is how can I load menu items from db on one place and after this send they to view? I don't want load this items in every controller/method.</p>
  
  <p>I am already tried make twig extension but after get this array i need iterate it and build html string in php class... I think it's a very bad idea...</p>
