How to show disable HTML select option in by default?

Question

I am new to HTML and PHP and want to achieve a drop-down menu from the mysql table and hard-coded too. I have multiple select in my page, One of them is

<select name="tagging">
    <option value="">Choose Tagging</option>
    <option value="Option A">Option A</option>
    <option value="Option B">Option B</option>
    <option value="Option C">Option C</option>
</select>

Problem is now that user can also select "Choose Tagging" as his tagging but i only want to provide him to chose from available three. I used disable as

<select name="tagging">
    <option value="" disabled="disabled">Choose Tagging</option>
    <option value="Option A">Option A</option>
    <option value="Option B">Option B</option>
    <option value="Option C">Option C</option>
</select>

But now "Option A" became the default one. So i want to set "Choose Tagging" as by default and also want to disable it from selection. Is it a way to do this. Same thing need to be done with other select which will fetch data from Mysql. Any suggestion will be appreciable.

Answer 1

use

<option selected="true" disabled="disabled">Choose Tagging</option>    

Answer 2

In HTML5, to select a disabled option:

<option selected disabled>Choose Tagging</option>

Answer 3

I know you ask how to disable the option, but I figure the end users visual outcome is the same with this solution, although it is probably marginally less resource demanding.

Use the optgroup tag, like so :

<select name="tagging">
    <optgroup label="Choose Tagging">
        <option value="Option A">Option A</option>
        <option value="Option B">Option B</option>
        <option value="Option C">Option C</option>
    </optgroup>
</select>

Electron + React Let your two first options be like this

<option hidden="true>Choose Tagging</option>
<option disabled="disabled" default="true">Choose Tagging</option>

First to display when closed Second to display first when the list opens

Answer 5

Another SELECT tag solution for those who want to keep first option blank.

<label>Unreal :</label>
<select name="unreal">
   <option style="display:none"></option>
   <option>Money</option>
   <option>Country</option>
   <option>God</option>
</select>

Answer 6

 selected disabled="true"

Use this. It will work in new browsers

Answer 7

Use hidden.

<select>
  <option hidden>Choose</option>
  <option>Item 1</option>
  <option>Item 2</option>
</select>

This doesn't unset it but you can however hide it in the options while it's displayed by default.

Answer 8

we can disable using this technique.

<select class="form-control" name="option_select">
  <option selected="true" disabled="disabled">Select option </option>
  <option value="Option A">Option A</option>
  <option value="Option B">Option B</option>
  <option value="Option C">Option C</option>
</select>

Answer 9

If you are using jQuery to fill your select element, you can use this:

html

<select id="tagging"></select>

js

array_of_options = ['Choose Tagging', 'Option A', 'Option B', 'Option C']

$.each(array_of_options, function(i, item) {
    if(i==0) { sel_op = 'selected'; dis_op = 'disabled'; } else { sel_op = ''; dis_op = ''; }
    $('<option ' + sel_op + ' ' + dis_op + '/>').val(item).html(item).appendTo('#tagging');
  })

This will allow the user to see the first option as a disabled heading ('Choose Tagging'), and select all other options.

Answer 10

You can set which option is selected by default like this:

<option value="" selected>Choose Tagging</option>

I would suggest using javascript and JQuery to observe for click event and disable the first option after another has been selected: First, give the element an ID like so:

<select id="option_select" name="tagging">

and the option an id :

<option value="" id="initial">Choose Tagging</option>

then:

<script type="text/javascript">

$('option_select').observe(click, handleClickFunction);

Then you just create the function:

function handleClickFunction () {

if ($('option_select').value !== "option_select") 
{
   $('initial').disabled=true; }
}
