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.

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:.

How to iterate through all selected elements into an array? Komal Agarwal Check out this Author's contributed articles. Load Comments.Select2 is a jQuery based replacement for select boxes.
It supports searching, remote data sets, and infinite scrolling of results. Select2 also supports multi-value select boxes.
The select below is declared with the multiple attribute. Select2 automatically picks up on this:. The placeholder can be declared via a data-placeholder attribute attached to the selector via the placeholder configuration element as seen in the example code. Optionally, a clear button visible once a selection is made is available to reset the select box back to the placeholder value.
Select2 supports a minimum input setting which is useful for large remote datasets where short search terms are not very useful:. Select2 uses a function to load result data. Here is a trivial example that creates choices that consist of user's input repeated a number of times:. Select2 allows the developer to limit the number of items that can be selected in a multi-select control.
In the example below only 3 or less items can be selected. Select2 provides some shortcuts that make it easy to access local data stored in an array instead of having to write a query function mentioned in the example above. Example below inlines the data by specifying an array in the data element. Items in such an array must have id and text keys.
If your data does not have a text key, an alternative key can be specified as a string:. In this example we will search for repositories using Github's API:.
If this example stops working, you have most likely reached the usage limit for the GitHub Search API of 5 requests per minute. Please wait a few minutes and try again. An alternative transport function can be specified in the ajax settings, or an entirely custom implementation can be built by providing a custom query function instead of using the ajax helper. Select2 supports lazy-appending of results when the result list is scrolled to the end.
In order to enable the remote service must support some sort of a paging mechanism and the query function given to Select2 must take advantage of it. The following example demonstrates how this can be set up. Search for some keyword and then scroll the result list to the end to see more results load:.
Note that when tagging is enabled the user can select from pre-existing tags or create a new tag by picking the first choice which is what the user has typed into the search box so far.The select tag in HTML is used to create a dropdown list of options which can be selected.
The option tag contains the value that would be used when selected. This is a boolean attribute. Output: Before clicking the list:. After clicking the list:. This option would have the hidden and disabled attribute in addition to selected. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.
