/**
|
|
* 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
|
|
