# Embedding URLs in a CFTREE

The HREF attribute in the CFTREEITEM tag allows you to designate tree items as links. To use this feature in a CFTREE, you simply define the destination of the link in the HREF attribute of CFTREEITEM.

| To embed links in a CFTREE:

1. Open a new file named `tree3.cfm` in Studio.
2. Modify the page so that it appears as follows:

       <CFFORM ACTION="submit.cfm">

           <CFTREE NAME="oak"
               HIGHLIGHTHREF="yes"
               HEIGHT="100"
               WIDTH="200"
               HSPACE="100"
               VSPACE="6"
               HSCROLL="no"
               VSCROLL="no"
               BORDER="no"
               DELIMITER="?">

               <CFTREEITEM VALUE="Important Links">
               <CFTREEITEM VALUE="Allaire Home"
                   PARENT="Important Links"
                   IMG="document"
       HREF="http://www.allaire.com">
               <CFTREEITEM VALUE="Allaire Forums"
                   PARENT="Important Links"
                   IMG="document"
       HREF="http://forums.allaire.com">
           </CFTREE>
       </CFFORM>

3. Save the page and view it in your browser.

| Make the node of the tree a link. Note HREF can refer to the name of a column in a query if the tree item is populated from that query.

## Specifying which tree items to send to the action page

When a user selects a tree item and submits the form, the CFTREEITEMKEY variable is appended to the URL passed to the application page specified in the CFFORM ACTION attribute, in the form:

    http://myserver.com?CFTREEITEMKEY=selected_value

You can disable this key by setting the APPENDKEY attribute in the CFTREE tag to No.
