By default every time you create a page they will be displayed in your website menu. WordPress dynamically creates your  navigation menu including your published pages.
With the Exclude Pages widget you can hide a page from appearing in the menu, and with the Parent Page and Order field you can select the position for your menu items.
Log into your site and navigate to the appropriate page you are wanting to exclude from your menu.

  1. Open the page you want to hide from your menu.
  2. At right hand side locate the Exclude Pages Widget

  5. Click on Update or Publish button to save your change.

Managing the position of your page in the menu
