How to remove search box from Chosen JS?

Question

On github it says that the search box was now optional in the chosen select boxes. Does anyone know how to remove it?

Answer 1

The current version of Chosen provides two methods to control the display of the search box. Both are passed in as options during initialization. To hide the search box completely pass in the option "disable_search": true:

$("#mySelect").chosen({
  "disable_search": true
});

Alternatively, if you want to show the search iff there are a certain number of options, use the option "disable_search_threshold": numberOfOptions (where numberOfOptions is the minimum number of options required before showing the search box):

$("#mySelect").chosen({
  "disable_search_threshold": 4
});

jQuery(function($) {
  // Create a set of OPTION elements from some dummy data
  var words = ["lorem", "ipsum", "dolor", "sit", "amet,", "consectetur", "adipiscing", "elit", "duis", "ullamcorper", "diam", "sed", "lorem", "mattis", "tristique", "integer", "pharetra", "sed", "tortor"],
      options = $($.map(words, function(word) {
        return $(document.createElement('option')).text(word)[0];
      }));
  $('select').each(function() {
    // Add the dummy OPTIONs to the SELECT
    var select = $(this).append(options.clone());
    // Initialize Chosen, using the options from the
    // `data-chosen-options` attribute
    select.chosen(select.data('chosen-options'));
  });
});

body {

  display: block;
  margin-bottom: 1.4em; }
  label .label {
    font-weight: bold;
    margin-bottom: .2em; }
select {
  width: 14em; }

just hide it when needed with

$('.chzn-search').hide();
