Select2 will now automatically update the selection if there are options added to or removed from the DOM within the `<select>` element. This is supported in all browsers except for Internet Explorer 8. Internet Explorer 8 does not support the DOM mutation events which were added in Internet Explorer 9, and it does not support mutation observers which are the recommended way of handling this in modern browsers. DOM mutation events also trigger for the `<select>` itself when it is pulled from the DOM, so we need to filter these out within the event handler. Despite supporting mutation observers, we cannot accurately detect if the removed option was selected at one time or another, so we need to always re-pull the selection when an element is deleted. This closes https://github.com/select2/select2/issues/4248 This builds upon https://github.com/select2/select2/pull/4249
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 https://select2.github.io/
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 nesting. 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.
Browser compatibility
