`%TREE{}%` synonym of `%TREEVIEW{}%`

Parameters

The following standard attributes are recognized

Parameter	Description	Default
`web`	The web to search.	current web
`topic`	Specify tree's root topic. If none the entire web topics' tree is generated	none
`formatting`	Specify the formatting method `ullist` is a <ul>-list, see sample UL lists `ollist` is a <ol>-list, see sample OL lists `outline` is an outline list, see sample Outlines `hlist` is a <h n >-list of section heads, see sample Headlines `coloroutline:colorlist` is an outline formatting with level values turned into colors, see sample Nested tables. Example: `formatting="coloroutline:#ffeeff,#eeffee,#ffffee,#eeeeff,#ffeeee,#eeffff"` `imageoutline:mode` is a way to incorporate images into the outline format, specifically to display thread-like and folder views, see sample Image Trees. The general format is: imageoutline: mode : images : imageformat. Example: `formatting="imageoutline:thread"` or `formatting="imageoutline:thread:I.gif,white.gif,T.gif,L.gif:<img src=\"$image\" border=\"0\">"`.	`outline`
`excludetopic`	Same meaning as VarSEARCH `excludetopic`. Topics with excluded parent or processed like topic without parent.	none
`includetopic`	Same meaning as VarSEARCH `topic`. Can improve processing time.	none
`startlevel`	The depth of the tree to start showing nodes from. To hide the root node, supply `startlevel="1"` (root is level 0). The displayed node depths are relative to the root topic.	`0` or `1` if `topic` is not specified
`stoplevel`	The depth of the tree to show, relative to start level.	`999`
`header`	Output the value within a `<div>` of class `treePluginHeader`. Suppressed if the tree is empty.	none
`footer`	Output the value within a `<div>` of class `treePluginFooter`. Suppressed if the tree is empty.	none
`zero`	Output the value within a `<div>` of class `treePluginZero` if the tree is empty.	none
`bookview`	List topics in BookView form. Not supported from v0.9. Instead use something like: %TREE{topic="GrandParent" formatting="outline" format="$outnum $topic <br /> $summary <hr />"}%	none
`format`	Specify the format for each node ( `outline` & `coloroutline`). The following pseudo-variable are supported on top of the ones described in FormattedSearch: `$spacetopic` - the topic with spaces `$level` - the tree depth of the topic (in whatever format) `$count` - the topic's child position `$index` - the index of the topic in the tree. Starts from one. Most useful when used in combination with TreeBrowserPlugin `$outnum` - outline number for the topic (eg, 1.3.4.2) `$url` - the current topic's URL Not supported. Use `%SCRIPTURL{view}%/$web/$topic` instead. `$author` - the topic's last author Not supported from v0.9. Use `%AUTHOR%` instead. `$modTime` - the topic's modification time. Not supported from v0.9. Use `$date` instead.	none
`formatbranch`	- specify the format for a group of children ( `outline` & `coloroutline`) `$parent` - the text of a node `$children` - the text of all the node's children (if any)	none
`levelprefix`	Specify a prefix to a node format. The prefix is inserted `$level` times at the beginning of the rendered node format. It allows generation of trees using Foswiki bullet list syntax thus enabling usage of TreePlugin in combination with TreeBrowserPlugin.	none
`nodiv`	Suppress the `<div>` around the tree. Set to `2` to suppress `div` around `header`, `footer` and `zero`. Allows for trees concatenation.	none
`separator`	Character string used to separate items in the tree	`\n`
`nocache`	Set to 1 to disable caching mechanism for that specific tree. Really a developer setting.	0
