Is tree view available in Finder in Lion?

I've seen on several forums that people use a tree view for their folders in Finder but I can't find anywhere how to switch to it.

Is the tree view available in OSX Lion?

Solution 1:

The way items are shown in Finder can be configured through the folder's Toolbar, which gives four default options:

• Icon View - Which is the regular layout of icons.
• List View - The items are shown in a list-like and can be navigated as a tree.

• Columns View - Items are displayed through columns which show the file's path.

• CoverFlow - Items are shown with the regular coverflow efect.

Note: While in a folder, you can switch through these options by doing Command + the option's number (1 is the icon's view, 2 is the list view, etc).
