I have a select
which initially shows Select language until the user selects a language. When the user opens the select, I don\'t want it to show a
The proper and semantic way is using a placeholder label option:
= ""
to that option
option
select
This will force the user to select another option in order to be able to submit the form, and browsers should render the option
as desired:
If a select element contains a placeholder label option, the user agent is expected to render that option in a manner that conveys that it is a label, rather than a valid option of the control.
However, most browsers will render it as a normal option
. So we will have to do fix it manually, by adding the following to the option
:
select > .placeholder {
display: none;
}
<select required>
<option class="placeholder" selected disabled value="">Select language</option>
<option>Option 1</option>
<option>Option 2</option>
</select>
Because you can't use assign placeholders for select
tags, I don't believe that there is any way to do exactly what you're asking for with pure HTML/CSS. You can, however, do something like this:
<select>
<option disabled="disabled">Select language</option>
<option>Option 1</option>
</select>
"Select language" will show up in the dropdown, but once another option is selected it will not be possible to reselect it.
I hope that helps.
Op1:
$("#MySelectid option").each(function () {
if ($(this).html() == "text to find") {
$(this).attr("selected", "selected");
return;
}
});
Op2:
$('#MySelectid option')
.filter(function() { return $.trim( $(this).text() ) == 'text to find'; }).attr('selected','selected');
Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML.
Adding a value of selected
to the item we want to appear as a header forces it to show in the first place as a placeholder.
Something like:
<option selected disabled>Choose here</option>
The complete markup should be along these lines:
<select>
<option selected disabled>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
You can take a look at this fiddle, and here's the result:
If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden
attribute like so:
<select>
<option selected disabled hidden>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
Check the fiddle here and the screenshot below.
<option value="" id="ddl" name="prop" style="display:none;" disabled selected>chose something </option>
you can of course move the css to a css file if you want, and put a script to catch the esc
button to select the disabled again. Unlike the other similar answers I put value=""
, this is so if you send the value(s) of your select list with a form, it won't contain "chose something". In asp.net mvc 5 sent as json compiled with var obj = { prop:$('#ddl').val(),...};
and JSON.stringify(obj);
the value of prop will be null.
I have a solution with a span displayed above the select until a selection done. The span displays the default message, and so it's not in the list of propositions:
HTML:
<span id="default_message_overlay">Default message</span>
<select id="my_select">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
</select>
CSS:
#default_message_overlay {
position: absolute;
display: block;
width: 120px;
color: grey;
}
select {
width: 150px;
}
Javascript (with JQuery):
$(document).ready(function() {
// No selection at start
$('#my_select').prop("selectedIndex", -1);
// Set the position of the overlay
var offset = $('#my_select').offset();
offset.top += 3;
offset.left += 3;
$('#default_message_overlay').offset(offset);
// Remove the overlay when selection changes
$('#my_select').change(function() {
if ($(this).prop("selectedIndex") != -1) {
$('#default_message_overlay').hide();
}
});
});
I've made a jsfiddle for demo. Tested with Firefox and IE8.
