How make select2 placeholder for search input
You can use the event:
select2:opening: Triggered before the dropdown is opened. This event can be prevented
It's enough to add the placeholder attribute in this event:
$(this).data('select2').$dropdown.find(':input.select2-search__field').attr('placeholder', 'My Placeholder')
$('select').select2({
placeholder: 'Select an option'
}).on('select2:opening', function(e) {
$(this).data('select2').$dropdown.find(':input.select2-search__field').attr('placeholder', 'My Placeholder')
})

<select style="width: 100%;">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
Use event select2:open.
$('#mySelect').select2().on('select2:open', function(e){
$('.select2-search__field').attr('placeholder', 'your placeholder');
})
I had the same need and I had ended up writing a small extension for the Select2
plugin.
There is a new option for the plugin, searchInputPlaceholder
, in order to set a placeholder for the 'search' input field.
Add the following code right after the plugin's js file:
(function($) {
var Defaults = $.fn.select2.amd.require('select2/defaults');
$.extend(Defaults.defaults, {
searchInputPlaceholder: ''
});
var SearchDropdown = $.fn.select2.amd.require('select2/dropdown/search');
var _renderSearchDropdown = SearchDropdown.prototype.render;
SearchDropdown.prototype.render = function(decorated) {
// invoke parent method
var $rendered = _renderSearchDropdown.apply(this, Array.prototype.slice.apply(arguments));
this.$search.attr('placeholder', this.options.get('searchInputPlaceholder'));
return $rendered;
};
})(window.jQuery);
Usage:
Initialize the select2 plugin with the searchInputPlaceholder
option:
$("select").select2({
// options
searchInputPlaceholder: 'My custom placeholder...'
});
