Is there a way to hide option
or optgroup
HTML elements? I've tried calling hide()
in jQuery, and also using regular Javascript to set style.display='none'
.
It works in Firefox but not in any other browsers. Actually removing them from the DOM does work, so perhaps there's a way to save each DOM element when it's removed, and reinsert them in the same place?
My HTML is like this:
<select name="propsearch[area]" id="propsearch_area">
<option value="0">- Any -</option>
<optgroup label="Bristol">
<option value="Hotwells">Hotwells</option>
<option value="Montpelier">Montpelier</option>
</optgroup>
<optgroup label="Cardiff">
<option value="Heath">Heath</option>
<option value="Roath">Roath</option>
</optgroup>
<optgroup label="Exeter">
<option value="Pennsylvania Road">Pennsylvania Road</option>
<option value="Lower North Street">Lower North Street</option>
</optgroup>
<optgroup label="Swansea">
<option value="Brynmill">Brynmill</option>
<option value="Uplands">Uplands</option>
</optgroup>
</select>
I figured that this solution works fine for me:
Make another select e.g.
$("#footer_canvas").after('<select id="parkingLot"></select>');
then hide it
$("#parkingLot").hide();
When you want to 'hide' some optgroup, just 'park' it in this hidden select.
$('#VehicleVehicleCategoryId optgroup[label="kategorie L"]').appendTo("#parkingLot");
Same way you can make it visible. This is just the snippets of my solution, that works fine for me.
