When you make any external changes that need to be reflected in Select2 such as changing the valueyou should trigger this event. This is further complicated by server-side filtering and pagination - there is no guarantee when a particular item will actually be loaded into the Select2 control! The best way to deal with this, therefore, is to simply add the preselected item as a new option. For remotely sourced data, this will probably involve creating a new API endpoint in your server-side application that can retrieve individual items:.

You can configure how Select2 searches for remote data using the ajax option. More information on the individual options that Select2 handles can be found in the options documentation for ajax.

Select2 will trigger some events on the original select element, allowing you to integrate it with other components. You can find more information on events on the options page. In addition to the dropdown menu of options, Select2 can also allow free-text responses.
This feature is called "tagging". To enable free-text responses, set the tags option to true :.

There's a JS Fiddle here that shows roughly what I have. What I want to know is what function I can attach to the button so that. I have tried all sorts of combinations of jQuery and Select2 data and val methods, called against various inputs on the page, but nothing seems to work The accepted answer below is very useful, helps shed some light on the right way to initialise the selection and explains what initSelection is for.
Having said that, it seems that my biggest mistake here was the way I was trying to trigger the change. Note: The Question and this Answer are for Select2 v3.

Change Selected option in Select2 Dropdown with jQuery
For most users, it should be:. If you search through the Select2 documentation for "initSelection", you will see that it is used when the element has an initial value and when the element's. That is because those values consist of only an id and Select2 needs the entire data object partly so it can display the correct label.
If the Select2 control was displaying a static list, the initSelection function would be easy to write and it seems like Select2 could supply it for you. In that case, the initSelection function would just have to look up the id in the data list and return the corresponding data object.

You may find it helpful to use a client-side templating engine like Handlebars to define your templates.
By default, strings returned by templateSelection are assumed to contain only text and will be passed through the escapeMarkup function, which strips any HTML markup. If you need to render HTML with your selection template, you must wrap your rendered selection in a jQuery object. In this case, the selection will be passed directly to jQuery. Any markup, such as HTML, will not be escaped and it is up to you to escape any malicious input provided by users.
Anything rendered as a selection is templated. This includes placeholders and pre-existing selections that are displayed, so you must ensure that your templating functions can support them.
