+<pre>~TiddlyWiki provides several macros for generating a tree of tiddler links by analysing [[tags|Tagging]]:
 
-!! Blog
-[[DropSea|https://dropseaofulaula.blogspot.com/]]
+;&lt;&lt;.var toc&gt;&gt;
+: A simple tree
+;&lt;&lt;.var toc-expandable&gt;&gt;
+: A tree in which all the branches can be expanded and collapsed
+;&lt;&lt;.var toc-selective-expandable&gt;&gt;
+: A tree in which the non-empty branches can be expanded and collapsed
+;&lt;&lt;.var toc-tabbed-internal-nav&gt;&gt; and &lt;&lt;.var toc-tabbed-external-nav&gt;&gt;
+: A two-panel browser:
+:* on the left, a selectively expandable tree that behaves like a set of vertical tabs
+:* on the right, the content of whichever tiddler the user selects in the tree
 
-!! Collaborazioni
+The difference between the last two has to do with what happens when the user clicks a link in the right-hand panel:
 
-!! Plugin e repositories su ~GitHub
+;&lt;&lt;.var toc-tabbed-internal-nav&gt;&gt;
+: The target tiddler appears in the right-hand panel, replacing the tiddler that contained the link
+;&lt;&lt;.var toc-tabbed-external-nav&gt;&gt;
+: The target tiddler appears in the normal way (which depends on the user's configured storyview)
 
-!!! Wordpress plugin
+!! Structure
 
-!!! Presentazioni e infografiche
+The top level of the tree consists of the tiddlers that carry a particular tag, known as the &lt;&lt;.def &quot;root tag&quot;&gt;&gt;. Tiddlers tagged with any of those make up the next level down, and so on.
+
+At each level, the tiddlers can be [[ordered|Order of Tagged Tiddlers]] by means of the &lt;&lt;.field list&gt;&gt; field of the parent tag tiddler. They can also be ordered by the macro's &lt;&lt;.param sort&gt;&gt; parameter.
+
+The tree displays the &lt;&lt;.field caption&gt;&gt; field of a tiddler if it has one, or the tiddler's title otherwise.
+
+Each tiddler in the tree is normally displayed as a link. To suppress this, give the tiddler a &lt;&lt;.field toc-link&gt;&gt; field with the the value &lt;&lt;.value no&gt;&gt;. In the [[examples|Table-of-Contents Macros (Examples)]], the SecondThree tiddler is set up like this. Clicking such a tiddler in the tree causes its branch to expand or collapse.
+
+The table of contents is generated as an HTML ordered list. The `&lt;ol&gt;` elements always have the class `tc-toc`. Expandable trees have the additional class `tc-toc-expandable`. Selectively expandable trees (including those in the two-panel browser) have `tc-toc-selective-expandable`.
+
+To make a table of contents appear in the sidebar, see [[How to add a new tab to the sidebar]].
+
+!! Parameters
+
+;tag
+: The root tag that identifies the top level of the tree
+;sort
+: An optional extra [[filter step|Filter Step]], e.g. `sort[title]`
+
+These two parameters are combined into a single [[filter expression|Filter Expression]] like this:
+
+&gt; `[tag[$tag$]$sort$]`
+
+&lt;&lt;.var toc-tabbed-internal-nav&gt;&gt; and &lt;&lt;.var toc-tabbed-external-nav&gt;&gt; take additional parameters:
+
+;selectedTiddler
+: The title of the [[state tiddler|StateMechanism]] for noting the currently selected tiddler, defaulting to `$:/temp/toc/selectedTiddler`. It is recommended that this be a [[system tiddler|SystemTiddlers]]
+;unselectedText
+: The text to display when no tiddler is selected in the tree
+;missingText
+: The text to display if the selected tiddler doesn't exist
+;template
+: Optionally, the title of a tiddler to use as a [[template|TemplateTiddlers]] for transcluding the selected tiddler into the right-hand panel
