This adds documentation for the `templateResult` and
`templateSelection` options. The fact that placeholders and
custom messages are templated was noted, although most people
should be using the standard `text` property that they provide
anyway. This fixes the templating link provided in the release
announcement to link to the correct location in the documentation.
This also adds support for the `templateSelection` function to
return a DocumentFragment or jQuery compatible object to be
passed back and rendered.

The `closeOnSelect` option was previously used to control whether
or not the dropdown was closed when an option was selected. This
could be simulated by triggering the `open` event after the `close`
event was received, but it makes sense to abstract it out into a
decorator.
This also adds support for not closing the dropdown when the control
key is being held. This is useful when multiple options need to be
selected in quick succession, so the dropdown does not have to be
reopened.
This also adds documentation that covers both changes.
This closes https://github.com/select2/select2/pull/2735.
This closes https://github.com/select2/select2/issues/3017.
This also fixes the case where `templateResult` does not return a
string, where it will fall back to jQuery to set the value of the
option. This allows for the `templateResult` function to return a
jQuery or DOM element that contains the templated data.
Just like with the translation methods, only strings returned from
`templateResult` will be escaped.
The old flag icons have been transferred from the old repository to
the documentation, for use in the templates. Unfortunately I cannot
find a license for them, but I suspect a license isn't actually
needed considering the state flags are public.

Select2 previously had an issue displaying the text of long values
as it was not correctly wrapping the text. This was because the
browser did not know that it couldn't wrap at whitespace, which
has been fixed.
Now Select2 should properly display an ellipsis for large text
values instead of overflowing.
This closes https://github.com/select2/select2/issues/2984.
In a single select, the search field is automatically focused when
the select is opened. This also applied to multiple selects, but
this was causing issues because the container was automatically
focused when the dropdown was closed.
This makes a change such that the search field is automatically
focused when the dropdown is closed.
This closes https://github.com/select2/select2/issues/2995.
The search box previously displayed a clear icon on the far right
side in webkit-based browsers, specifically Chrome and Safari. This
hides the clear icon in those browsers, and also fixes a slight
sizing issue, so it should no longer be displayed.
This also disables autocorrect, autocompleted, as well as a few
other automatic search corrections on the field, so mobile devices
should have a better experience.

This splits out the two templating functions that are referenced in
the documentation. The two functions were previously available in
the source code, but they were not named with the method names that
the documentation referred to.
This closes https://github.com/select2/select2/issues/2993.
In past versions of Select2, supplying a value less than zero to
`minimumResultsForSearch` acted the same as providing a high value,
such as `Infinity`. This corrects the regression by mapping anything
less than zero to the value `Infinity`.
This closes https://github.com/select2/select2/issues/2994.
It is assumed that DOM elements or related objects will have been
escaped before they are passed back from templating functions. As
strings are typically blinding concatenated, like in our defaults,
it makes sense to escape the markup within them.
This is related to https://github.com/select2/select2/issues/3005.
It appears as though GitHub has stopped serving the Placeholder.js
GitHub Pages site. This broke placeholder support on older versions
of IE in the documentation and broke the link we had to the
polyfill. Since the repository is still online, and the
documentation should work without an internet connection, the
JavaScript files have been pulled into the documentation folder.
Translations will now be passed through `escapeMarkup` and injected
into the results messages as HTML just like the templating options
for the the results and selections. This fixes the regression from
3.x where the old formatters always supported HTML.
This closes https://github.com/select2/select2/issues/3008.
The `allowClear` option may not work as intended if a placeholder
is not used. This is becaise the placeholder holds the value that
the `<select>` should be reset to when the `x` is hit.
An error is now properly raised in the console when Select2 detects
that the `allowClear` option is used without the `placeholder`
option.
This closes https://github.com/select2/select2/issues/3016.
I18n translations expect a "maximum" argument for inputTooLong message,
but MaximumInputLength is passing "minimum". This renames "minimum" to
"maximum" to fix this problem.
This adds back the `ajax.transport` option, which allows anyone to
use their own AJAX backend. By default, `jQuery.ajax` is used as the
default transport backend.
**Breaking change:** Instead of taking `params` that contains a
`success` and `error` keys for the callback, two new callback
parameters are passed alongside of `params` that should be called
when the request succeeds or fails.
This closes https://github.com/select2/select2/issues/2987.
This is needed to escape any bad markup that is passed through
user-entered data. Users can prevent their markup from being
escaped by using a no-op `escapeMarkup` function.
This closes https://github.com/select2/select2/issues/2990.
Now we are using `jQuery.noConflict()` in tests, so it should be
slightly easier to detect when this happens next time. Tests just
need to be written for the component.

This adds documentation for the revised `matcher` function, as well
as the compatibility `oldMatcher` function for those who are
upgrading.

This prevents scrolling within scrollable containers (excluding the
dropdown) when the dropdown is open. This fixes an issue where the
dropdown would go out of sync with the parent container when the
parent container was scrolled.
We did not have this issue in past versions of Select2 because the
mask prevented any scrolling. Now that we have removed the mask, we
have to deal with scrolling from different areas of the page.
We initially tried to hook into the `scroll` events of the parent
containers, but because of a list of issues we decided against it.
If the container scrolled out of view, the dropdown would still be
left open and above everything else, even though the container
wasn't visually connected to it.
The `scroll` event does not bubble, so we need to attach the `scroll`
handler to every parent element that is scrollable. Since it is
surprisingly difficult to determine if an element is scrollable,
we modified some CC-BY-SA code and use that to determine if the
element has a scrollbar. The original `hasScroll` function can be
found at http://codereview.stackexchange.com/q/13338, the same link
left within the code, and was originally designed to be a sizzle
selector. As Select2 does not require a sizzle-compatible version of
jQuery, we converted it into a function that could be used with
`.filter` to filter down the elements.
This closes https://github.com/select2/select2/issues/2975.
Select2 did not previously have a high enough `z-index` for it to
be displayed over modals. The `z-index` has been raised to 1051,
so now it should appear over the jQuery UI and Bootstrap modals.
This closes https://github.com/select2/select2/issues/2958.
When Select2 is not used with a design that universally sets
`box-sizing: border-box` to elements, the search box previously
would take up more space than expected. This fixed the issue by
adding the `box-sizing` rule to the search box.
This closes https://github.com/select2/select2/issues/2978.
When we re-implemented support for responsive widths, through the
use of percentages, we never moved the support over to the dropdowns.
So the dropdowns generally were not large enough, and when resized
they never re-adjusted, and they didn't fully work as intended.
This fixes the issue by automatically resizing the dropdown whenever
it is repositioned, mainly to handle new scrollbars, which will
ensure that it is always the same width as the container.
This also adds a section to the examples for responsive design,
just like in the old documentation.
This closes https://github.com/select2/select2/issues/2949.
This reverts the changes (from 3.5.x) to the scroll detection, so
Select2 will still reposition itself every time the window is
scrolled or resized. This has the benefit of fixing the issue when
the screen jumps if the dropdown is too high, which would previously
close the dropdown.
Select2 will also correctly set the positioning if it is pushed out
of the top of the viewport. Due to an unexpected bug, Select2 would
previously still display above the container, but would be styled
as if it were below it.
This closes https://github.com/select2/select2/issues/2961.
This closes https://github.com/select2/select2/issues/2956.
This fixes an issue where an `unselect` event would be incorrectly
triggered when the selected option was selected again in a single
select. This has been fixed now, so the even will only be triggered
for multiple selects. The `close` event will still be triggered
though, so the functionality will still remain the same to the user.
This closes https://github.com/select2/select2/issues/2959.
The `selectOnClose` option did not work in production because we
were decorating the `dropdownAdapter` instead of the `resultsAdpater`
when automatically generating the adapters. This has now been fixed,
and the option should work without errors in production.
This also adds documentation for the `selectOnClose` option.
This closes https://github.com/select2/select2/issues/2953.
