如何在不使用选择器刷新网页的情况下导航到其他网站或网页？

Question

I wonder how can I be able to create a webpage like this?

so the user can navigate to other websites or pages without seeing their address and just by selecting the desired page from the drop down menu?

here is the other example

http://demo.rockettheme.com/joomla-templates/epsilon/

I have to clarify that the URL that you are visiting in the Address Bar is

http://www.yootheme.com/demo/joomla

But after you have selected the Frequency Theme for example from the menu you are seeing this URL again

http://www.yootheme.com/demo/joomla but the frequency theme is hosted here:

http://yoocore.com/demo/themes/joomla/2014/frequency/

and could you please tell me the name of this method or if any specific plugin or tool available to create such a website?

Answer 1

It's an iframe. Here's part of the source code:

<iframe frameborder="0" onload="" 
    src="http://yoocore.com/demo/themes/joomla/2014/digit/index.php?style=default"
    border="0" id="iframe" style="top: 56px; left: 0px; width: 1353px; height: 275px;">
</iframe>
