How to delete side menu in any sub-menu page

Hey,

wanted to ask how to remove the side menu (along the right side of the content) from almost every sub-menu page? Quick example on this sub-menu - http://www.chslabrador.cz/anabel-od-paseckeho-potoka/ (search text box and all other options below that)

Thanks a lot guys!

Hello there,

Edit your page and then enable either Front Page or Full width template in Page Attributes option.
