Native Select

General

You need to use a fetchCallback property to format the data of the API callback, which will match the data structure of the component.

Asynchronous requests are not executed by default

Set property firstRequestAutoExec to false. The first asynchronous request is not executed (saving bandwidth and improving performance). Trigger the first asynchronous request when the options area is expanded.

`wrapperClassName`	string	`mb-3 position-relative`	The class name of the control wrapper.	-
`options`	JSON Object Literals \| JSON Object	-	Set the default value using JSON string format for menu of options, like this: `[{"label": "Option 1","value": "value-1"},{"label": "Option 2","value": "value-2"},{"label": "Option 3","value": "value-3","customAttr1": "attr1","customAttr2": "attr2"},{"label": "Option 4","value": "value-4","disabled":true}]` Note: Use API data if database query exists. That is, the attribute `fetchXXXX`	-
`hierarchical`	boolean	false	Set hierarchical categories ( with sub-categories ) to attribute `options`.	-
`indentation`	string	-	Set hierarchical indentation placeholders, valid when the `hierarchical` is true.	-
`doubleIndent`	boolean	false	Set double indent effect, valid when the `hierarchical` is true.	-

If you use objects, you can default to values that do not exist in the option list. such as `{"label":"Option 0","value":"value-0","queryString":""}` (Single selection only!!!)	-
`value`	string \| JSON Object	-	Set a default value for this control. If you use objects, you can default to values that do not exist in the option list. such as `{"label":"Option 0","value":"value-0","queryString":""}` (Single selection only!!!)	-

Note: the first element is a query string, the second element is the number of queried data (usually a number), and then you can increase the third, or fourth, and more parameters. Such as `['',0]`, `['',99,'string 1','string 2']` There should be at least one parameter which is the query string.	-
`fetchCallback`	function	-	Return value from `fetchCallback` property to format the data of the API callback, which will match the data structure of the component. At the same time it returns the original data, you will use this function and use the `return` keyword to return a new value.	-
`onFetch`	function	-	Call a function when data is successfully fetched. It returns one callback value which is the fetched data (Array)	-
`onChange`	function	-	Call a function when the value of an HTML element is changed. It returns four callback values.

`disabled`	boolean	-	When present, it specifies that an option should be disabled.	-
`callback`	function	-	Click on the callback function for this option.	-

Create Callback

A successful response returns the details of the callback such as Sample Request Body:

Among them, label, listItemLabel, value, optgroup, disabled and callback are attributes used by the system, and other attributes can be added freely
