Also, I doubt that this would work without re-initializing the select2 plugin. Why the down vote? You did state 'I need to add values to the selected list. Try it. Selectednot select. Also, if you would've looked at the code, you'd see that I was changing the value thus the selected onces and not the options of the select.

I think now you all are clear with my requirement. Please let me know if you need further clearance. I get this post is old but there have been changes to how select2 works now and the answer to this question is extremely simple now.
Also there will be times you will not want to fire the change event because you might have some other code that will execute which is what will happen if you use the method above so to get around that you can change the value without firing the change event like so.

Every single item is wrapped in li. I would really appreciate if there is also some other class added to currently selected item in this ul.
That way I can target it by CSS and hide that item. This change would only affect the single select. The multi select already uses a css class for selected items called select2-selected. If a CSS class were to be added to the currently selected element, it should be added in both single and multiple select modes for consistency.
The elements of a multiple select cannot be selected multiple times, once an item is selected it gets removed from the results filtering is done using the select2-selected class. In the case of the single select, the selected element still shows up highlighted in the results. What srigi mentions is beeing able to hide this element from the results the same way it happens for multi select. Maybe what we really should do is allow to user to hide the currently selected element from the results in a single select.
For instance, if you have already selected Oregon then it doesn't show up in the result list as in the following example:. This way we would use the same CSS class for both single and multi select select2-selected. This option could be a boolean configuration value called hideSelectionInSingle false by default. Later it could be made more generic once the multi select allows duplicated items.
Closed by The pull request was reverted because of issues discovered in I'm open to a revised implementation, though I'm not sure how it would be possible to get past the val issue. Could you also revert the documentation for it?
Select2's internal data structure filters out duplicate, this could be changed but would require lots of changes. The way I ended up doing it is as follow: I added a property to allow the same item to be selected multiple times only for multiple select. When the user submits the page, I keep track of the seleted elements inside a hidden input:. Commenting the code that prevents the same item to be selected multiple times is an option example provided by kanthu This issue was closed because of work in but that pull request was reverted, so the problem remains.
Do authors of select2 4. I just updated select2 from 3. It would be best to hide selected options and show some text on empty list. Hiding options with CSS is not a good solution: in fact, it is not a solution at all. As it has already been said if you try to navigate the options with the keyboard keys it will still cycle through the hidden options, which makes hiding the selected options with CSS a terrible decision because it breaks usability.Select2 also supports multi-value select boxes.
The select below is declared with the multiple attribute. Click this to focus the single select element. Click this to focus the multiple select element. A placeholder value can be defined and will be displayed until a selection is made. You can support it in older versions with the Placeholders. Select2 provides a way to load the data from a local array. You can provide initial selections with array data by providing the option tag for the selected values, similar to how it would be done for a standard select.
If you need to provide default selections, you just need to include an option for each selection that contains the value and text that should be displayed. 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. You can also initialize Select2 with disabled: true to get the same effect.
Select2 will correctly handle disabled results, both with data coming from a standard select when the disabled attribute is set and from remote sources, where the object has disabled: true set. First Second disabled Third. Select2 multi-value select boxes can set restrictions regarding the maximum number of options selected. The select below is declared with the multiple attribute with maximumSelectionLength in the select2 options. Select2 allows you to hide the search box depending on the number of options which are displayed.
In this example, we use the value Infinity to tell Select2 to never display the search box. 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 :. Note that when tagging is enabled the user can select from the pre-existing options or create a new option by picking the first choice, which is what the user has typed into the search box so far.
Tagging can also be used in multi-value select boxes. Try entering a value that isn't listed in the dropdown - you'll be able to add it as a new option! Select2 supports ability to add choices automatically as the user is typing into the search field. Try typing in the search field below and entering a space or a comma. The separators that should be used when tokenizing can be specified using the tokenSeparators options.
Unlike other dropdowns on this page, this one matches options only if the term appears in the beginning of the string as opposed to anywhere:. This custom matcher uses a compatibility module that is only bundled in the full version of Select2. You also have the option of using a more complex matcher.Select2 is licensed under MIT. When an option is selected from the dropdown menu, Select2 will display the selected value in the container box.
By default, it will display the text property of Select2's internal representation of the selected option. The appearance of selected results can be customized by using the templateSelection configuration option. This takes a callback that transforms the selection data object into a string representation or jQuery 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. Select2 multi-value select boxes can set restrictions regarding the maximum number of options that can be selected. The select below is declared with the multiple attribute with maximumSelectionLength in the select2 options.
When set to truecauses a clear button "x" icon to appear on the select box when a value is selected. Clicking the clear button will clear the selected value, effectively resetting the select box back to its placeholder value. Getting Started Installation Basic usage Builds and modules 2.
