Is there a way to set properties to the <options> of <select> (dropdown)?
I have:
Code: <select id="sth" name="bla">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
This is done automatically from the foreach loop.
But, I need:
Code: <option id="sth" value="bla">bla</option>
Why do I need this?
Select is list of all countries. I wanna store the country phone code in ID and the value to be country name. That way, when user changes the country (from drop down) I can update phone country code automatically. Work around is to create another Ajax call to get the code upon .change() but would rather avoid this 
Thanks!

Do you mean to say, each option would have their own unique id?
The options tag supports the standard attributes:
Quote:class
dir
ltr
id
lang
style
title
xml:lang
The CI form_dropdown() function, only supports passing multiple attributes to the <select>, and not the <option>. You can modify this yourself by re-writing this function adding in the functionality to pass attributes to the <option>.
I've done this myself for other form functions where there was no ability to even pass attributes to a form element in the first place... This is especially true with the table library which lacks the same capability throughout, and is missing key structure elements for creating a table!

Well, that's what I have eventually done
In case anyone needs same functionality:
in helpers/form_helper.php (around line 350 in function form_dropdown())
was:
Code: function form_dropdown($name = '', $options = array(), $selected = array(), $extra = ''){}
// changed to:
function form_dropdown($name = '', $options = array(), $selected = array(), $extra = '',$id=FALSE)
// and was:
else
{
$sel = (in_array($key, $selected)) ? ' selected="selected"' : '';
$form .= '<option value="'.$key.'" '.$sel.'>'.(string) $val."</option>\n";
}
// Changed to:
else
{
if($id==TRUE)
{
$sel = (in_array($key, $selected) OR in_array($val,$selected)) ? ' selected="selected"' : '';
$form .= '<option value="'.$val.'" id="'.$key.'" '.$sel.'>'.(string) $val."</option>\n";
}
else
{
$sel = (in_array($key, $selected)) ? ' selected="selected"' : '';
$form .= '<option value="'.$key.'" '.$sel.'>'.(string) $val."</option>\n";
}
}
I used this approach not to break functionality of the function for all other dropdowns I am using

Hey,
i know that this thread is a bit old, but i was also looking for a quick solution and i tried something and its working, without editing any helper or core.
Code: $options = array(
'small" class="small_class' => 'Small Shirt',
'med" class="med_class' => 'Medium Shirt',
'large" class="large_class' => 'Large Shirt',
'xlarge" class="xlarge_class' => 'Extra Large Shirt',
);
$shirts_on_sale = array('small', 'large');
echo form_dropdown('shirts', $options, 'large');
// Would produce:
<select name="shirts">
<option value="small" class="small_class">Small Shirt</option>
<option value="med" class="med_class">Medium Shirt</option>
<option value="large" selected="selected" class="large_class">Large Shirt</option>
<option value="xlarge" class="xlarge_class">Extra Large Shirt</option>
</select>
Its working and the form validation still works
Hope this will help somebody.
Greeting from Germany
Richard!

You can also generate the HTML the old fashioned way, if a helper is ever limiting what you're trying to output.
[eluser]richiejaeger[/eluser]
Sure, you could
But the thread is about form_dropdown() ^^
