How to show disable HTML select option in by default? - html

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

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 3

In HTML5, to select a disabled option:
<option selected disabled>Choose Tagging</option>

Answer 4

Electron + React.
Let your two first options look 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

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>

Answer 6

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 7

<select name="dept" id="dept">
<option value =''disabled selected>Select Department</option>
<option value="Computer">Computer</option>
<option value="electronics">Electronics</option>
<option value="aidt">AIDT</option>
<option value="civil">Civil</option>
</select>
use "SELECTED" which option you want to select by defult.

Answer 8

selected disabled="true"
Use this. It will work in new browsers

Answer 9

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 10

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.

<option value="saab">Saab</option>

<option value="audi">Audi</option>
</select>

Answer 12

This will hide the option for you this easier that to make a other dropdown box
<option selected="true" disabled="disabled">Choose Tagging</option>

Answer 13

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; }
}
