Widgets provide rich functionality within WikiText. They have the same syntax as [[HTML elements|HTML in WikiText]], but the tag name always starts with `$`. For example:

```
<$button message="tm-close-tiddler">Close Me!</$button>
```

Note that widgets inherit all the features of [[HTML in WikiText]]:

* Widget attributes can be specified as:
** Unquoted strings (that cannot contain spaces)
** Strings quoted with single or double quotes
** Strings quoted with triple-double quotes
** Macro invocations (eg `attr=<<myMacro>>`)
** Transclusions (eg, `attr={{MyTiddler!!field}}`)
** Filtered transclusions (eg, `attr={{{ [filter[op]] }}}`)
* The content of a widget is [[parsed|WikiText Parser Modes]] in [[inline mode|Inline Mode WikiText]] unless the opening tag is followed by two linebreaks, which forces [[block mode|Block Mode WikiText]]
** [[inline mode|Inline Mode WikiText]] means that [[block mode|Block Mode WikiText]] parse rules like headings, tables and lists are not recognised

See [[HTML in WikiText]] for more details.
