Select2 autocomplete by option value

Question

I have tried to integrate tag/autocomplete for my site. Its working through option text. I am almost close to result but still hanging.

Now when you try to select option

Answer 1

To remove the double-ups of the Id and the Text showing when entering just the Id check whether the entered term matches an existing Id, and if it does simply return the Text of the matching option:

options = [];

// create an array of select options for a lookup
$('.custom-select option').each(function(idx) {
    options.push({id: $(this).val(), text: $(this).text()});
});


$("select").select2({
  tags: "true",
  placeholder: "Select an option",
  allowClear: true,
  width: '100%',
  createTag: function (params) {
    var term = $.trim(params.term);

    if (term === '') {
      return null;
    }
    
    // check whether the term matches an id
    var search = $.grep(options, function( n, i ) {
      return ( n.id === term || n.text === term); // check against id and text
    });
    
    // if a match is found replace the term with the options' text
    if (search.length) 
      term = search[0].text;
    else
      return null; // didn't match id or text value so don't add it to selection
    
    return {
     id: term,
     text: term,
     value: true // add additional parameters
    }
  }
});

$('select').on('select2:select', function (evt) {
  //console.log(evt);
  //return false;
});

.select2-container {
  max-width: 400px;
}
