Question

Is there anyway to make select option as selectable/auto complete/searchable? unfortunately i cannot change the form. so i cannot change the select option into text field. but i be able to access the css and javascript..

Below is the select option.

<select name="siteID" id="siteID" class="abcd" style="width:100%" /> 
            <option value='0' selected='true'> Not associated to any Circuit ID </option>
            <option value='2101' > 1007345136 </option> 
            <option value='2102' > 1007921321 </option> 
            <option value='2103' > 1007987235 </option> 
            <option value='2407' > 132 </option> 
            <option value='2408' > 141 </option> 
            <option value='2409' > 142 </option> 
            <option value='2410' > 145 </option>

            <option value='3301' > circuit id 50 </option> 
            <option value='2105' > fadhil </option> 
            <option value='2104' > faisal </option> 
            <option value='3002' > IPEN - SITE TEST </option> 
            <option value='3601' > Manual Circuit ID </option> 
            <option value='3302' > new circuit id fadhil </option> 
            <option value='1809' > try iframe </option> 
        </select>

is there any javascript/jquery and css that can transform it as serchable.

Answer 1

Check out Chosen.

I tried both select2 and selectize and neither worked properly for me. I'm currently using jQuery 1.9.x. Chosen worked first try on 3.6 with basic tests but not sure if it will work well in current jQuery versions with all browsers.

[Update] In my production environments, I'm using jQuery 1.9.x with Chosen and it runs rock solid for my usecases.

Answer 2

For those who are using bootstrap in their project, a searchable select can be made using dropdown buttons. Add an input field inside the dropdown menu and use javascript to filter through the options.

A detailed explanation with example can be found on the following blog:

Answer 3

Ok, I understand that you cannot change the select to anything else but those who are searching for similar thing and can change the select to datalist, it is very simple:

<input list="weekday">
<datalist id="weekday">
  <option value="Sunday">
  <option value="Monday">
  <option value="Tuesday">
  <option value="Wednesday">
  <option value="Thursday">
  <option value="Friday">
  <option value="Saturday">
</datalist>

Answer 5

Display: none will not work foe IE11

I had same issue for search in select option.

What I did is disabled the un matched options and the hide them.

After this I have sorted the options to show only enabled options on top.

The code I have written is pasted below - please try to understand the logic I hope it will work

to disable the options use:

$("#addselect option")attr('disabled', 'disabled').hide

and to again enable it use:

$("#addselect option").removeAttr('disabled').show();

to sort by disabled options:

$("#addselect option").each(function (i, val) {
    if ($(this)[i].disabled) {
        moveDown("selectId");
    }
    else {
        moveUp("selectId");
    }
}

function moveUp(selectId) {
    var selectList = document.getElementById(selectId);
    var selectOptions = selectList.getElementsByTagName('option');
    for (var i = 1; i < selectOptions.length; i++) {
        var opt = selectOptions[i];
        if (!opt.disabled) {
            selectList.removeChild(opt);
            selectList.insertBefore(opt, selectOptions[i - 1]);
        }
    }
}

function moveDown(selectId) {
    var selectList = document.getElementById(selectId);
    var selectOptions = selectList.getElementsByTagName('option');
    for (var i = selectOptions.length - 2; i >= 0; i--) {
        var opt = selectOptions[i];
        if (opt.disabled) {
            var nextOpt = selectOptions[i + 1];
            opt = selectList.removeChild(opt);
            nextOpt = selectList.replaceChild(opt, nextOpt);
            selectList.insertBefore(nextOpt, opt);
        }
    }
}

You can use javascript to include other scripts like explained here:

How do I include a JavaScript file in another JavaScript file?

function includeJs(jsFilePath) {
    var js = document.createElement("script");

    js.type = "text/javascript";
    js.src = jsFilePath;

    document.body.appendChild(js);
}

Then you could solve your problem using Selectize:

includeJs("https://code.jquery.com/jquery-2.1.4.min.js");
includeJs("https://cdn.rawgit.com/brianreavis/selectize.js/master/dist/js/standalone/selectize.js");

$(function() {
    $('select').selectize();
});

You will also need to include in your css the rules from selectize.css (or you could create a link element using a similar includeCss function in Javascript)

Note that in the fiddle I fixed the autoclosing <select /> (not allowed)

Answer 7

You may consider using a jQuery plugin called Select2. You cannot self-close a <select> tag! You can just use it this way:

$(function () {
  $("select").select2();
});

@import url(https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/css/select2.min.css);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/js/select2.full.min.js"></script>
<select name="siteID" id="siteID" class="abcd" style="width:100%">
  <option value='0' selected='true'> Not associated to any Circuit ID </option>
  <option value='2101' > 1007345136 </option> 
  <option value='2102' > 1007921321 </option> 
  <option value='2103' > 1007987235 </option> 
  <option value='2407' > 132 </option> 
  <option value='2408' > 141 </option> 
  <option value='2409' > 142 </option>

  <option value='2702' > 248 </option> 
  <option value='2703' > 251 </option> 
  <option value='2704' > 254 </option> 
  <option value='2705' > 264 </option> 
  <option value='1804' > 27 </option>
