Change the full-page slider type's height

The full-page slider type is checking the size of the window, and it will make the slider that big (unless if there is a container, that doesn’t allow it to be that big). You can change this size in it’s file:
Joomla plugins\nextendslidertype\fullpage\fullpage\slider.js
WordPress wp-content\plugins\nextend-smart-slider2-full\plugins\nextendslidertype\fullpage\fullpage\slider.js
Magento app\code\community\Nextend\SmartSlider2\plugins\nextendslidertype\fullpage\fullpage\slider.js

At this code (around line 120.):

var screenSize = {
     w: window.innerWidth,
     h: window.innerHeight
};

You can decrease the height, so there would be space for your top menu, or something else. Here I will decrease it with 100px:

var screenSize = {
     w: window.innerWidth,
     h: window.innerHeight-100
};

Every part of this slider is calculated from this code, so it can only be changed in it’s file, and it will affect every full page type slider. One more thing, that you should do is to go to the Edit SliderType: Full-page type – ConfigureFocus, and turn off the options, because they only work, if the slider has the height of the screen.
