|
|
Select2 provides the `SelectAdapter` as a default implementation of the `DataAdapter` adapter. It extends `BaseAdapter`.
|
|
|
|
This adapter can be overridden by assigning a custom adapter to the `dataAdapter` configuration option.
|
|
|
|
**AMD Modules:**
|
|
|
|
- `select2/data/base`
|
|
- `select2/data/select`
|
|
|
|
## Decorators
|
|
|
|
### `Tags`
|
|
|
|
This decorator implements the [tagging](/tagging) feature.
|
|
|
|
**AMD Modules:**
|
|
|
|
`select2/data/tags`
|
|
|
|
### `MinimumInputLength`
|
|
|
|
This decorator implements the [minimum search term length](/searching#minimum-search-term-length) feature as exposed through the `minimumInputLength` configuration option.
|
|
|
|
**AMD Modules:**
|
|
|
|
`select2/data/minimumInputLength`
|
|
|
|
### `MaximumInputLength`
|
|
|
|
This decorator implements the [maximum search term length](/searching#maximum-search-term-length) feature as exposed through the `maximumInputLength` configuration option.
|
|
|
|
**AMD Modules:**
|
|
|
|
`select2/data/maximumInputLength`
|
|
|
|
### `InitSelection`
|
|
|
|
This decorator provides backwards compatibility for the `initSelection` callback in version 3.5.
|
|
|
|
In the past, Select2 required an option called `initSelection` that was defined whenever a custom data source was being used, allowing for the initial selection for the component to be determined. This has been replaced by the `current` method on the data adapter.
|
|
|
|
**AMD Modules:**
|
|
|
|
`select2/compat/initSelection"`
|
|
|
|
### `Query`
|
|
|
|
This decorator provides backwards compatibility for the `query` callback in version 3.5.
|
|
|
|
**AMD Modules:**
|
|
|
|
`select2/compat/query`
|
|
|
|
### `InputData`
|
|
|
|
This decorator implements backwards compatibility with version 3.5's `<input type="hidden" >` elements.
|
|
|
|
In past versions of Select2, a `<select>` element could only be used with a limited subset of options. An `<input type="hidden" >` tag was required instead, which did not allow for a graceful fallback for users who did not have JavaScript enabled. Select2 now supports the `<select>` element for all options, so it is no longer required to use `<input />` elements with Select2.

|
|
**AMD Modules:**
|
|
|
|
`select2/compat/inputData`
