Adding customize widgets on other screen pages

When I swipe to spotlight search screen (keep swiping to the right, the first page), i see a bunch of widgets on that screen. At the bottom, there is a stack of widgets. When i edit widgets, this section appears as 'Customize' and when i try to customize this section, the see a widget for almost every app i have on phone. I can change the order of the widgets in this customize section but I cannot move around the whole section. I am trying to add a widget from this customize section to another page on my screen, e.g. I can add accuweather widget in the customize section but when i go to another page and try to add a widget, i dont see any accuweather widget. How do i add accuweather widget to another page.
