Restore select2 input functionality after Bootstrap 5 cleanup

- Restored select2 input type from earlier commit d4adf5e^
- Added select2 import to bootstrap5-editable.js bundle
- Updated demo with select2 example (requires select2 library)
- Enhanced README.md with comprehensive select2 documentation
- Includes support for static sources, AJAX sources, and advanced configuration
- Select2 library must be included separately (not bundled)

/**
Select2 input. Based on amazing work of Igor Vaynberg https://github.com/ivaynberg/select2.
Please see [original select2 docs](http://ivaynberg.github.com/select2) for detailed description and options.
You should manually download and include select2 distributive:
<link href="select2/select2.css" rel="stylesheet" type="text/css"></link>
<script src="select2/select2.js"></script>
To make it **bootstrap-styled** you can use css from [here](https://github.com/t0m/select2-bootstrap-css):
<link href="select2-bootstrap.css" rel="stylesheet" type="text/css"></link>
**Note:** currently `autotext` feature does not work for select2 with `ajax` remote source.
You need initially put both `data-value` and element's text youself:
<a href="#" data-type="select2" data-value="1">Text1</a>
@class select2
@extends abstractinput
@since 1.4.1
@final
@example
<a href="#" id="country" data-type="select2" data-pk="1" data-value="ru" data-url="/post" data-title="Select country"></a>
<script>
$(function(){
//local source
$('#country').editable({
source: [
{id: 'gb', text: 'Great Britain'},
{id: 'us', text: 'United States'},
{id: 'ru', text: 'Russia'}
],
select2: {
multiple: true
}
});
//remote source (simple)
$('#country').editable({
source: '/getCountries',
select2: {
placeholder: 'Select Country',
minimumInputLength: 1
}
});
//remote source (advanced)
$('#country').editable({
select2: {
placeholder: 'Select Country',
allowClear: true,
minimumInputLength: 3,
id: function (item) {
return item.CountryId;
},
ajax: {
url: '/getCountries',
dataType: 'json',
data: function (term, page) {
return { query: term };
},
results: function (data, page) {
return { results: data };
}
},
formatResult: function (item) {
return item.CountryName;
},
formatSelection: function (item) {
return item.CountryName;
},
initSelection: function (element, callback) {
return $.get('/getCountryById', { query: element.val() }, function (data) {
callback(data);
});
}
}
});
});
</script>
