/**
 * Select widget
 *
 * At its most basic, you can select one option from a list provided.  The list can be passed from the server in
 * the sel_options array or options can be added as children in the template.  Some extending classes provide specific
 * options, such as Et2SelectPercent or Et2SelectCountry.  All provided options will be mixed together and used.
 *
 * To allow selecting more than one option, use the attribute multiple="true".   This will take & return an array
 * as value instead of just a string.
 *
 * SearchMixin adds additional abilities to ALL select boxes
 * @see Et2WithSearchMixin
 *
 * Override for extending widgets:
 * # Custom display of selected value
 * 	When selecting a single value (!multiple) you can override doLabelChange() to customise the displayed label
 * 	@see Et2SelectCategory, which adds in the category icon
 *
 * # Custom option rows
 *  Options can have 'class' and 'icon' properties that will be used for the option
 * 	The easiest way for further customisation to use CSS in an external file (like etemplate2.css) and ::part().
 * 	@see Et2SelectCountry which displays flags via CSS instead of using SelectOption.icon
 *
 * # Custom tags
 * 	When multiple is set, instead of a single value each selected value is shown in a tag.  While it's possible to
 * 	use CSS to some degree, we can also use a custom tag class that extends Et2Tag.
 * 	1.  Create the extending class
 * 	2.  Make sure it's loaded (add to etemplate2.ts)
 * 	3.  In your extending Et2Select, override get tagTag() to return the custom tag name
 *
