Hello
I have a select list and I need a way to set certain option tags invisible. I tried applying style="display:none" to the option tags but this has had no effect.
The reason for this is that I am going to use some JavaScript to dynamically enable some selections in the drop down list.
Please see the attached code snippet.
Thanks

<select id="counties" tabindex="1">
 <option value="">Select</option>
 <option style="display:none" value="IE76176089">Carlow</option>
 <option style="display:none" value="IE96268862">Cavan</option>
 <option style="display:none" value="IE55624026">Clare</option>
 <option style="display:none" value="GB55624026">London</option>
 <option style="display:none" value="GB55624026">Surrey</option>
</select>

You can't hide options, you have to remove them from the select list if you don't want them to show up.

Here is how you dynamically add an option to the select list:

var o = document.createElement('option');
o.value = 'IE76176089';
o.text = 'Carlow';
document.getElementById('counties').options.Add(o);
