! Content and Attributes
The content of the `<$list>` widget is an optional template to use for rendering each tiddler in the list. Alternatively, the template can be specified as a tiddler title in the ``template`` attribute. As a fallback, the default template just displays the tiddler title.
The content of the `<$list>` widget is an optional template to use for rendering each tiddler in the list.
The action of the list widget depends on the results of the filter combined with several options for specifying the template:
* If the filter evaluates to an empty list, the text of the ''emptyMessage'' attribute is rendered, and all other templates are ignored
* Otherwise, if the ''template'' attribute is specified then it is taken as the title of a tiddler to use as a template for rendering each item of the list
* Otherwise, if the list widget content is not blank, it is used as a template for rendering each item of the list
* Otherwise, a default template is used consisting of a `<span>` or `<div>` element wrapped around a link to the item
