Q: What are the terms of use for the free version of the Treeview?
(For info on the paid version, see the next question.)

A: These are the terms of use:

You cannot redistribute the Treeview, or another tree script based on
it, as a standalone product. You can, however, distribute HTML
applications that include the tree in it. An example of this is an
electronic book where the Treeview applet is used to help navigate
between the pages.

There are no royalties to be paid for the distribution of products
that use the Treeview inside of them.

You can make changes to the tree menu script, as long as you keep all
the source comments (inside the code; not visible to the users)
regarding the author of the script (Marcelino Martins) and the origin
of the code (www.Treeview.net) in all the source files directly
associated with the script (HTML, JS, ASP, etc.).

You cannot simply remove the "JavaScript Tree Menu" from the free
version. See Removing the top link.

Corporate users are generally encouraged to upgrade to a paid
version. (To go directly to the purchase page click here.) If the site
your company is building is not public, i.e. if it is only going to be
visible on the intranet of the company, then, more than encouraged,
the upgrade is strongly recommended.
