The select widget displays a popup menu based on a [[HTML select element|https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select]]. The popup (or dropdown) contains a list of items defined by `<option>` and `<optgroup>` elements.
Every time the user selects a new value in the menu, the selected value is written to the text of a specified tiddler field or index. If the tiddler value changes the menu is automatically updated to reflect the new value.
In multiple selection mode, the list of selected values is bound to the specified tiddler field or index. Browsers generally use the <kbd>ctrl</kbd> or <kbd>cmd</kbd> keys for multiple selection.
For example, this select widget displays a list of the tags in this wiki:
<$macrocall $name="wikitext-example-without-html" src="<$select tiddler=<<qualify 'select-demo'>> default='HelloThere'>
