I have made a drop down in which you can select multiple items but i want no item to be selected by default but when i come this page i get first item selected by default . I don't know how to set it as unselected at start.
<select>
<option disabled selected> </option>
<!-- Normal other options goes here -->
</select>
Add this extra option.
[or]
If you have JQuery/JavaScript, do the following
document.getElementById("dropdown").selectedIndex = -1;
$("#dropdown").prop("selectedIndex", -1);
No you cannot do without an extra option/without JS/JQuery. It is the default behaviour of dropdown
If you want no item to be selected you can just add this before your first option:
<option></option>
Update: For the multiple select: this should work fine
<select name="cars" multiple="multiple">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>

I created a drop down list with links. It works properly except when I go back one page, then instead of the option which is 'selected' in the HTML, it shows the option I had navigated to. I would like it to reset, so that the page I'm on is the one being displayed when the list is collapsed. How can I fix this?
<div id="drop">
<select name="year" id="year" onchange="location = this.value;">
<option value="sermons-2023.html"selected>2023</option>
<option value="sermons-2022.html">2022</option>
<option value="sermons-2021.html">2021</option>
<option value="sermons-2020.html">2020</option>
<option value="sermons-2019.html">2019</option>
<option value="sermons-2018.html">2018</option>
<option value="sermons-2017.html">2017</option>
<option value="sermons-2016.html">2016</option>
<option value="sermons-2015.html">2015</option>
</select>
</div>
You have to save the value with js in localstoreg and then after returning to the previous page you can see that the value is the same
Here is the code I am having issues with:
<select name="webmenu" id="filter_option" style="width: 175px; " onchange="searchTree($(this).val());">
<option value="">--View All--</option>
<option value="Tree">Tree</option>
<option value="Dog Approval">Dog Approval</option>
<option value="Cat">Cat</option>
<option value="Sky">Sky</option>
I have an issue with the dropdown in that when I select this: <option value="">--View All--</option> in chrome the list does not load all default values when this option is selected.
When I go into chrome inspector and look at the line: <option value="">--View All--</option> the option value looks like this: <option>--View All--</option>
Why is it stripping out the value="" part of the code?
without the code ot link to that site I cannot guess what exactly is happening at your side.
but answering the question from the title…
you can only select multiple options if the attribute multiple is present in the tag select. then to make an option tag selected it needs the attribute selected.
so to select all options, all option tags need an attribute selected.
read up: select, multiple, option
<!doctype html>
<html>
<head><title></title></head>
<body>
<select size="5" multiple>
<option selected value="1">1</option>
<option selected value="2">2</option>
<option selected value="3">3</option>
<option selected value="4">4</option>
<option selected value="5">5</option>
</select>
</body></html>
if you can maybe add your problem to the above playground and a solution might be found through that.
I have a select like this :
<select name="cars" multiple>
<option value="volvo" selected>Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
I would like the option "Volvo" selected by default and required, but the user can unselect it if he wants. I would like that the user would not be able to unselect it.
This select is generated with PHP, so I can add an hidden field, but I want the user to know that this option is required. How can I do that?
When option is selected by default, without 'selected' text in it. How is it possible?.
I actually need a different option but I am not able to choose anything.
// set by default selected value using "selected" property of option
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel" selected>Opel</option>
<option value="audi">Audi</option>
</select>
// if you don't specify form select default option is first one "Volvo"
Default first one option is selected without "selected" property set beacuse that default behavior is that
If no "selected" attribute is provide, the first option in the select list will be selected by default. It will work this way in all browsers. Using an option with no text or value gives the appearance that nothing is selected:
<select>
<option value=""></option><!-- this will be selected by default, but the value will be empty string-->
<option value="1">Value 1</option>
<option value="2">Value 2</option>
<option value="3">Value 3</option>
</select>
I have a dropdown select list, from which I can choose a country. the first option is: choose your country.
<select>
<option selected disabled value=''>Choose your country</option>
<option value="1">Canada</option>
<option value="2">France</option>
</select>
But when I click to open the list, I can see choose your country in the options. Is there a way to hide this option from the list, and only show it as a placeholder before any selection is made?
Hides the default option from appearing in the list:

IMO the better solution would be to use something like: http://harvesthq.github.io/chosen/
<select>
<option value='' disabled selected style='display:none;'>Choose your country</option>
<option value="1">Canada</option>
<option value="2">France</option>
</select>
Use display:none; on your first value:
<select>
<option value="" selected disabled style="display:none;">Choose your country</option>
<option value="2">Canada</option>
<option value="3">France</option>
</select>
