Hi, why is it different in the document and in my panel, I can’t select other items
On the left is what my setup looks like, and on the right is what it looks like in the document
I want to customize the domain name, but I can’t follow the tutorial on the documentation, please help me, am I missing something?
You will not be able to remove the .netlify.app domain since this is your sites Netlify sub-domain controlled by Netlify. If you add your own domain, you will be able to remove it.
If you are trying to edit the Netlify sub-domain, you can edit the site’s name in site settings
Hope this helps 
Thank you for your reply, but you may have misunderstood what I meant.
I want to customize the domain
You currently do not have a domain linked to Netlify. You have what we call a sub-domain and it ends with .netlify.app. This is given to all Netlify sites and you can change the text before .netlify.app by changing your site name in site settings.
If you have a custom domain (which you currently do not have linked to the site) then you will need to add this with the add domain button.
