With the recent changes to how Select2 works internally, this really isn't needed. This has been added to make the migration path easier, and it just internally calls `val` on the underlying select element. The only difference is that the `val` function will now convert any non-string elements to strings. The second argument (`triggerChange`) has not been migrated, as Select2 now internally relies on the `change` event. **Note:** As the old `initSelection` method has not been migrated, it is not possible to set the `val` on remote data sources where the value has not previously been selected.
Select2
Select2 is a jQuery-based replacement for select boxes. It supports searching, remote data sets, and pagination of results.
To get started, checkout examples and documentation at http://ivaynberg.github.io/select2
Use cases
- Enhancing native selects with search.
- Enhancing native selects with a better multi-select interface.
- Loading data from JavaScript: easily load items via ajax and have them searchable.
- Nesting optgroups: native selects only support one level of nested. Select2 does not have this restriction.
- Tagging: ability to add new items on the fly.
- Working with large, remote datasets: ability to partially load a dataset based on the search term.
- Paging of large datasets: easy support for loading more pages when the results are scrolled to the end.
- Templating: support for custom rendering of results and selections.
