I have several Checkbox
<div class="checkbox">
<label>
<input type="checkbox" class="chkItem" name="Selected" value="1" /> A
</label>
</div>
<div class="checkbox">
<label>
<input type="checkbox" class="chkItem" name="Selected" value="2" /> B
</label>
</div>
<div class="checkbox">
<label>
<input type="checkbox" class="chkItem" name="Selected" value="3" /> C
</label>
</div>
How do I create a "Search" search for the letter "C" for example and hide all other checkboxes?
