nested Layouts

When created, the 'Layout' object 'grabs' user input from the screen. What you'd need to do is just create a Layout object as and when you want it rather than trying to keep them in RAM all the time (it's also better for memory usage):

Thanks, will try that!

I don't really understand what you're asking here...

Here is an example, i basically want to go from the main menu to the adjustment page without the intermediate menu. Is there a way to do that?

var Layout = require("Layout");
var a=50;

var adjustA = {
  '< BACK>': initMainMenu,
  'A': {
    value:  a, min:0, max:100, step:1,
    format: function(value) {
      return (value);
    },
    onchange: function(value) {
      a=value;
    }
  }
};

function initMainMenu() {
  var mainMenu = new Layout (
    {type:"btn", font:"15%", fillx:1, filly:1, label:"adjust A", cb:l=>E.showMenu(adjustA)}
  );
  g.clear();
  mainMenu.render();
}
initMainMenu();
