How to use 2 template in 1 site?

Hello maxpeerawat,

Unfortunately, you cannot use 2 templates at the same time. Each of template (demo content) has a different style. If you want to have the same design with travel demo, for instance, you have to do some customization in order to achieve this design.

This is the simplest solution of recreating the travel demo homepage on another demo. This cannot be done without the custom classes used by this demo.
Please follow these simple steps to recreate the travel demo homepage with another demo installed:

1) This is the shortcode of the page layout. You can simply paste it inside your page editor in classic mode and text mode: http://screencast.com/t/SUt9ItUc the code: http://pastebin.com/RAA6DkWp

2) The background image will not be found so you will need to add your own image in the row setting: http://screencast.com/t/yB2Bh0rbo

3) This is the final and most important step as the CSS for the travel homepage will not apply without this step. Please add this class: td-travel to the body of the website like so: http://screencast.com/t/fOt9sfquQtVy

This will be the result: http://screencast.com/t/vlZG4G8m1Xpy

Hope this helps and let us know how it goes!

Thank you for the message!
