in Studio.
<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>
Code | Description |
---|---|
HREF="http://www.allaire.com"> | Make the node of the tree a link. |
HREF="http://forums.allaire.com" | 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. |
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.
