Menu
I have a select that contain this values:
<select id="lstCities" class="valid" name="City">
<option value="OSNY">OSNY</option>
<option value="dd">dd</option>
<option value="OSffNY">OSffNY</option>
<option value="ANTONY">ANTONY</option>
<option value="0">Autre...</option>
</select>
How can I delete all options but i would like to keep only
<option value="0">Autre...</option>
My problem is my list is dynamic sometimes I have 3,5,7,.... select + the last one <option value="0">Autre...</option>

Explanation: If we want to remove all items from dropdown except the first item then we can use $('#ddlItems option:not(:first)'). remove(); Here we have excluded first item from being deleted. If we want to remove all items from dropdown except the last item then we can use $('#ddlItems option:not(:last)').
Approach: Select the option from select which needs to remove. Use JQuery remove() method to remove the option from the HTML document.
The option to be removed is selected by getting the select box. The value to be removed is specified on the value selector (value='optionValue') on the select box. The remove() method is then used to remove this selected option. The find() method can be used to find the option in the value with the value selector.
select all options, then exclude the one with that value :
$('#lstCities option[value!="0"]').remove();
