I already made it with folders, but when I create a folder, takes an extra space, that I don't like, that's why i ask for this..

Sorry, I don't understand what you want.

There are numerous bookmark related add-ons to rearrange your Bookmarks Toolbar so you can fit more. They may also include some capabilities that you can't achieve with the built-in settings. I haven't tried any of them recently, but you can explore here:

Search Results for "bookmarks"

Here's an example of that i want, photoshop helped here, is it possible to make it like this?

Hi, you can have as many folders within folders as you like; just right click in a folder > New Folder... is that what you want to know?

I know that, but it's not what i want, I uploaded a picture with an example what i want in previous post!

Sorry, adding a "folder structure" to a 'bookmark" as you have pictured isn't possible.
