While deep nesting will not work on a standard `<select>`, we can
emulate it through data objects still, and just handle the display
of the data in the results.
This also means that the horrific deep-nested CSS is back to handle
the padding. I hope that will get fixed over time.
This also fixes one of the performance issues with adding array
data, as options are added at the very end instead of one by one.
Due to a change in 7edf0e3ebe that
made the rendered selection take up the full width of the selection
container, the placeholder was not being automatically displayed.
The calculations were always turning out negative, which has been
fixed by not trying to automatically calculate the best possible
width.
Because of the change made previously to make events global, any
time a result message was triggered there would be a stack overflow.
This was because we were re-triggering the event locally if it
happened on a global level, which would start the loop.
This has been fixed so the event is never caught locally, but
instead uses the global handler.
The `AllowClear` decorator appears to work fine with multiple
selects, so we've chosen to remove remove it. This adds some
styling and fixes the check so it all works as expected.
This closes https://github.com/select2/select2/issues/2903.
This fixes an issue where the `x` in multiple selects (visible next
to the option) would be visible even if the container was disabled.
Because it was still accepting events as well, this would cause the
underlying data to be changed, even though it was disabled. We now
hide the icon using CSS so this issue doesn't occur.
The same applies to the `x` for clearing a placeholder.

Also pull the logic for automatically closing the dropdown into the
dropdown adapter, taking it out of the core.
The `selected` and `unselected` events are now `select` and
`unselect`, which is what many of the other adapters were expecting
them to be.
Some tests for placeholders have been added.
Tagging should be demonstrated using the multiple select, as that
is where it really shines. It's also how we used to demonstrate it.
This closes https://github.com/select2/select2/issues/2901.
Now Select2 can fire jQuery events that will match the corresponding
internal events. The `open` and `close` events are now publicly
accessible.
The selection adapter was chosen because it is the least likely to
be moved, but handles the most common events. This `EventRelay`
decorator should theoretically be able to decorate any of the
adapters, as they all have the `bind` method that it needs.
The star event will allow us to relay any custom events as well as
the ones used internally by Select2. This also makes it much
easier to start triggering events in general, as we don't need to
relay it in the core anymore.
A module has been created for the jQuery-facing events, and the
release announcement has been updated to mention the event name
changes.
This also adds some documentation about the public events.
For the dropdown search on single select instances, the search
focus should happen in a `setTimeout` call. This is because many
browsers trigger the element focus on `click`, so our original call
to `$search.focus` will essentially be ignored. By also focusing
it in a timeout, this will delay the call to `focus` so the browser
will no longer take it back.
We do not have this issue for multiple select instances, as they
trigger the `open` event on `click`, instead of using `mousedown`.
This fixes https://github.com/select2/select2/issues/2900.
The package files (bower, npm, etc.) now point to the new
distribution locations, and have the beta version numbers in place.
The version number has been removed from the `bower.json` and
`composer.json` files as they will retrieve the version numbers
from Git.
There was a plan to universally use an array as the return from
query methods, but now that we've realized pagination and extra
things are impossible without it, we're going back to the return
object. Anyone looking to migrate their data should be returning
an object with the key `results` containing what they previously
returned.
This should fix https://github.com/select2/select2/issues/2898
This fixes the SASS error caused by the `&[dir="rtl"]` selector in
the `_single.scss` and `_multiple.scss` files. We were expecting
these files to be nested within the `.select-container` class, which
would have made this a non-error as the `&` would refer to the
`.select2-container` class that was wrapping the `@import`.
This moves the `@import` statements into the `.select2-container`
class, so this no longer triggers an error in the Ruby version of
SASS.
This closes https://github.com/select2/select2/issues/2896
jQuery.mousewheel will allow us to prevent the dropdown from
automatically closing when the user scrolls to the end of the list.
It is automatically bundled in the full versions of Select2 and
we don't require that it is included in order for Select2 to work.
jQuery.mousewheel was taken directly from the source repository
using the commit at
cc2c5d73ae
I'm still not quite sure how this should be handled for the general
case, but for the special case we have this for infinite scrolling,
only on AJAX data.
This will always clone the options that are passed in when
initializing Select2 on multiple objects (like `$("select")`) so
it doesn't always assume that the configuration is the exact same.
This prevents any reference-based tricks for modifying the data
within Select2, but some would look at that as an upside.
The documentation for templates still needs to be created.
A warning is now generated in the console for applications using
the previous data attributes that have been migrated.
Now that the data objects have the `element` property, we can test
to make sure it's a DOM element and then use it for selecting the
option. This allows us to select multiple options with the same id,
as well as handle cases where that is already happening.
You cannot use `$e.val()` to select two options with the same id,
as jQuery will reject it, but you can set the second option to
`.selected = true`, which is supported.
alt-down/up is the standard way of opening a select when using a
screen reader. This also fixes the gradient in IE, so now it
displays the right colors. Also added a note about Placeholders.js,
so the placeholders on multi-select boxes will work in IE 9 and
below.
Added a disabled state for Select2. This will correctly listen to
property changes (so when the disabled property is changed) and
update the state of Select2 to reflect it.
Added a utility function to find a method to a different context.
With the recent changes to how Select2 works internally, this really
isn't needed. This has been added to make the migration path
easier, and it just internally calls `val` on the underlying select
element. The only difference is that the `val` function will now
convert any non-string elements to strings.
The second argument (`triggerChange`) has not been migrated, as
Select2 now internally relies on the `change` event.
**Note:** As the old `initSelection` method has not been migrated,
it is not possible to set the `val` on remote data sources where
the value has not previously been selected.
The backspace key now behaves very similar to how it does in other
multiple select boxes, such as the one that Stack Exchange uses.
When the user presses the backspace key, the last selected option
is unselected and the search box is filled with the text of the
option.
