!! Nested Lists
This example uses a nested pair of list widgets. The outer one generates the `<optgroup>` elements, and the inner one generates `<option>` elements:
<$macrocall $name="wikitext-example-without-html" src="<$select tiddler='$:/generated-list-demo-nestedstate' field='type' default='text/vnd.tiddlywiki'>
<$list filter='[all[shadows+tiddlers]prefix[$:/language/Docs/Types/]each[group]sort[group]]'>
<optgroup label={{!!group}}>
<$list filter='[all[shadows+tiddlers]prefix[$:/language/Docs/Types/]group{!!group}] +[sort[description]]'>
<option value={{!!name}}><$view field='description'><$view field='title'/></$view> (<$view field='name'/>)</option>
</$list>
</optgroup>
</$list>
</$select>"/>
