I notice that if you add multiple to a select element then all of the options are shown, while without multiple the element has a drop down button. I would like to have the drop down button and then be able to select multiple items from the drop down list. Is this possible?
There's a jsfiddle here: http://jsfiddle.net/Z6KWr/3/
<select id="delete_dropdown" multiple>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
</select>
Thanks
No, the dropdown cannot allow multiple selection. For doing so you have to use some other plugin which will allow multiple selection while looking like a dropdown.
There are some plugins which you can find here

This is not possible in HTML. If you're interest in jQuery plugins then check
Multiple Select in Chosen.js
or
Multi-Value Select Boxes in Select2.js

I'm making a dropdown menu in HTML and was trying to figure out how to pre-select a drop down value when the page loads. I've tried the following, using the selected option to indicate what value I want to be the default upon load. Though, this doesn't seem to work and I still end up with the first option being the default. I'm sure it's really simple but is there
<select selected="3">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
</select>
Rather than manually put it in the <option value> tag, since these options are being generated via a loop, is there a way in the <select> tag to indicate what option should be defaulted? Thanks.
Use the selected property of the <option> you want selected by default:
<select>
<option value="1">1</option>
<option value="2">2</option>
<option value="3" selected>3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
</select>
You can set that property programatically, if you update your question to include how you are generating, I can update this to show you how.
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.
If you have
<select>
<option value="val1">Teemo bot</option>
<option value="val2">Teemo mid</option>
<option value="val3">Akali mid</option>
</select>
How do I make it, when you click on one, it transfers you to another site.
you might want to use on change, since you are unable to select a option if first click redirects.
<select onchange="javascript:document.location=this.options[this.selectedIndex].value;">
<option value="http://google.com">Google</option>
<option value="http://stackoverflow.com/">Stackoverflow</option>
</select>
Does there exist a way to store two separate values in a select form element? For instance
<select>
<option value="">A + B</option>
</select>
I would like to store values A and B separately, but select them both with one option.
You can add two options:
<option value="a">A</option>
<option value="b">B</option>
Is this what you need?
Use a multiple select instead:
<select name="yourChoices[ ]" multiple>
<option value="A">A</option>
<option value="B">B</option>
</select>
Users are able to choose more than one option.
Here is an example: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select_multiple
Is there a way to add an additional 'submenu' to a dropdown list on a contact form? So it would technically work like a drop-down navigation.
Below is the drop-down list for my contact form. And i've been asked to see if I can add additional options to lets say, Existing Partner. So when they hover over that item it expands to other options.
<label for="hear">How did you hear about us? </label>
<select class="contact-drop-down" name="hear" id="hear">
<option>Click to choose</option>
<option value="1">Existing Partner</option>
<option value="2">Word of mouth</option>
<option value="3">Brochure</option>
<option value="4">Email mailshot</option>
<option value="5">Google</option>
<option value="6">Yahoo</option>
<option value="7">Bing</option>
<option value="8">Other search engine</option>
<option value="9">Other</option>
</select>
You can't expand on hover with the standard select within HTML, but you can with either Javascript or HTML5 and CSS3.
This site has a list of 30 examples of HTML5 navigation menus and this site has a large selection of Javascript and JQuery examples.
Hopefully one of these might help you get what you want.
You can use optgroup tag for this.
<select>
<optgroup label="Existing Partners">
<option value="existing_partner_a">Partner A</option>
<option value="existing_partner_b">Partner B</option>
<option value="existing_partner_others">Others</option>
</optgroup>
</select>
No you cannot add sub menu to actual dropdown control. But you may find many custom controls.

Saurabh Goyal above suggested to use . I also thought of suggesting the same. But is used for categorization & I dont think thats what you want.
Try optgroup for this .for example
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>
</select>
