I have a <select> element defined like this:
<select>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
I would like to get the same functionality (being able to select an option), except I want to permanently display all the options, instead of hiding them in a drop-down-list. I basically want to make a listbox.
Would this be possible?
Is there already an element that will do this?
Would I have to modify the element?
Try to use size attribute in your select widget
code
<select name="file_type" size="8">
<option value=".jpg">.JPG</option>
<option value=".png">.PNG</option>
<option value=".gif">.GIF</option>
</select>

I have an issue with the <select> element. When I set the multiple attribute, Chrome automatically scrolls to the last <select> that has an <option> with the selected attribute.
ex: http://jsfiddle.net/j1yrxzpp/
<select multiple="multiple">
<option selected="selected">1</option>
<option>2</option>
</select>
Have you any ideas about this ?
There is a bug for this issue https://code.google.com/p/chromium/issues/detail?id=423256
For example, a drop-down list that has the options 1,2 and 3 but has the default text "Make a selection..." without that being a selectable option.
If that's confusing here is a fiddle. Basically, I don't want you to see "make a selection..." in that example when you click on the drop down. Just 1,2 and 3.
I assume it could be done with some javascript but that seems hackish.
Code:
<select>
<option>make a selection...</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
<select>
<option selected="true" disabled="true" >make a selection...</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
http://jsfiddle.net/Et4VH/
Looks like you can do this using display:none:
<select>
<option style="display:none">make a selection...</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
Working example: http://jsfiddle.net/66Tbz/2/
Try this:
<select>
<option disabled="true" >make a selection...</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
If that won't work for you, you might have to resort to Javascript, intercepting clicks and canceling them.
ETA: Or perhaps combine them: when clicking on the dropdown, disable the "make a selection" option, ensuring the user can only select one of the other options. The challenge would be to find an event to trigger enabling "make a selection" again.
ETA: Well, the following would probably be at the outer limits of "reasonable to spend time on", but I include it for completeness: You could build a "control" that consisted of a label and a hidden listbox, with a graphic to the right of the label to trigger the visibility of the list box. You'd need javascript, and it would be a nuisance to get the appearance quite right, but it could do exactly what you've described.
But if you get to that point, you might as well just script up some click handlers for a regular dropdown, and tweak its behavior.
You could add a disabled attribute as Ann suggested, but then the default would not be visible per default anymore.
Use a <label> to recommend the selection, do not use a meaningless <option> for that.
<label for="foo">Select something</label>
<select name="foo" id="foo">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
Try this:
<select>
<option selected="selected" disabled="true" >make a selection...</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
You could write a validation javascript function and display a error if the user has not selected any option
<form onSubmit="validate()">
<select>
<option>make a selection...</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</form>
Instead of using an inline style, (assuming an id of "selectid" on the select object) why not set #selectid > option:first-child{ display: none; } ?
I forked your fiddle. (heh, heh)
http://jsfiddle.net/qV9kp/
<select>
<option value="" disabled="true">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
Is it possible to dynamicaly resize the visible options in select tag in forms? I have the example:
<select size="1">
<option value='1'>1
<option selected value='2'>2
<option value='3'>3
<option value='4'>4
</select>
I would like to have visible all options (to setup size dynamically with css) when design page for printing. And also to see selected option(s) in another design (color, bold ...). For resize I tried:
select{
size:4;
}
but it doesn't work. I need a working solution at least for FF, IE, Safari ...
Do have any idea?
Thanks in advance!
You can use this way:
<select size="1" size="4">
<option value='1'>1</option>
<option selected value='2'>2</option>
<option value='3'>3</option>
<option value='4'>4</option>
</select>
And don't forget to close the </option>
Does native HTML have a listbox element? You know how it has a drop box element (called select), does it also have a listbox?
If not, do you know how I could place a list box in my Website.
One method, is to create a table & have each element detect the onclick event. But I dont want to make my own just yet. Are javascript widgets easy to use?
Use a select list:
<select multiple="multiple" size="2">
<option value="Whatever">One</option>
<option value="Other">Two</option>
</select>
#Myles has the select box which is correct, you can also allow multiple select options.
<select multiple="multiple">
<option value="opt1">Option 1</option>
<option value="opt2">Option 2</option>
<option value="opt3">Option 3</option>
</select>
Add the multiple attribute to a normal <select> and use the size attribute to determine how many rows you want shown. (If you don't set the size attribute, then all options will be visible.):
<select multiple="multiple" size="5">
See example.
I think what you need is the select tag, but set the selects attributes of multiple and size. Here is a reference http://www.w3schools.com/tags/tag_select.asp.
<select multiple='multiple' size='3'>
<option value='o1'>Red</option>
<option value='o2'>Green</option>
<option value='o3'>Blue</option>
</select>
At this moment the standards do not have a listbox element.
There's a web spec in progress about the <selectmenu> element which does have a listbox slot (not element). Possibly this could end up being back in the <select> element

Is there any way to have a drop-down list in which non of the items are selectable? So basically, I'm just looking to use it as a way of showing/hiding a list. I don't want any hover highlighting and I don't want to be able to change the selected item.
Could you suggest if this is possible, or if anyone has any other ideas to achieve something similar, could you point me to a good example.
Thanks
The optgroup tag comes to mind. It has a disabled attribute.
<select>
<optgroup label="My List" disabled>
<option value="item1">Item 1</option>
<option value="item2">Item 2</option>
</optgroup>
</select>
However, IE 6 and 7 don't respect the disabled. Arrgh. Neither do they listen to the readonly attribute slapped on the whole select.
You will have to add a onchange="this.value ='item1';" fallback for those browsers, which obviously isn't watertight if JavaScript is turned off.
