Change site title to a hover over with other text and other link.

Site URL: https://colettesmith.squarespace

Hi, I am attempting to replicate a site for a course - and this is the original site https://lassefloede.com/ does anyone know how to code the title like this? Where you hover over the name (site-title) and get another text appearing e.g. About,  with a link to that page when clicked. 

I've been trying to do this a while so any help would be greatly appreciated! 

My site has a temp password : punocourse

Thanks 

The site you want to look like is not a Squarespace site. It is built wih Craft CMS and hosted on Blix Solutions. Any code would need to be targeted to your specific template so for any chance of getting help you would need to post the site you are building and if you don't have one yet let us know what template you  are looking at using in Squarespace 7.0 or  7.1.  If you have a trial site working still post the url and provide the password, which you set in config/settings/ site availability. 

If you share link to your site, we can give the code to achieve this.
