code:

html:

<ul name="events-categories" id="events-categories">     <li><input type="checkbox" name="category-events" value="185" placeholder="" id="category-185" class="events-category"> conventions         <ul class="event-children">             <li><input type="checkbox" name="child-category-all" value="" class="events-child-category-all">all</li>             <li><input type="checkbox" name="child-category-190" value="190" id="child-category-190" class="child events-child-category">science</li>             <li><input type="checkbox" name="child-category-191" value="191" id="child-category-191" class="child events-child-category">technology</li>         </ul>     </li>     <li><input type="checkbox" name="category-events" value="184" placeholder="" id="category-184" class="events-category"> music         <ul class="event-children">             <li><input type="checkbox" name="child-category-all" value="" class="events-child-category-all">all</li>             <li><input type="checkbox" name="child-category-189" value="189" id="child-category-189" class="child events-child-category">blues</li>             <li><input type="checkbox" name="child-category-188" value="188" id="child-category-188" class="child events-child-category">jazz</li>             <li><input type="checkbox" name="child-category-187" value="187" id="child-category-187" class="child events-child-category">rock n roll</li>         </ul>     </li>     <li><input type="checkbox" name="category-events" value="186" placeholder="" id="category-186" class="events-category"> tributes</li> </ul>​

css:

.event-children {     margin-left: 20px;     list-style: none;     display: none; }​

jquery far:

/**  * left sidebar events categories  * toggle sub categories  */ $('.events-category').change( function(){     console.log('showing sub categories');     var c = this.checked;     if( c ){         $(this).next('.event-children').css('display', 'block');     }else{         $(this).next('.event-children').css('display', 'none');     } });  $('.events-child-category-all').change( function(){     var c = this.checked;     if( c ){         $(this).siblings(':checkbox').attr('checked',true);     }else{         $(this).siblings(':checkbox').attr('checked',false);     } });​
