I'm trying to figure how how to make the check-box make an inventory item collapse and expandable. I'm not sure what I'm doing wrong and I'm open to help or alternatives. I appreciate any help I can get for this, I don't know where I'm going wrong or how to accomplish this exactly. Here's what I got... <div class="melee-sheet"> <table cellpadding="10" cellspacing="0"> <tr> <td colspan="3" class="sheet-statlabel-big-gray" style="font-size: 1.5em; width: 450px;">Strength Weapons</td> </tr> </table> <fieldset class="repeating_meleeweapons"> <label class="labelcheck" title="collapse this item"> <input name="attr_simpleinventory" type="checkbox" value="hide"> <span style="font-size: 12px;">Collapse</span> </label> <table cellpadding="0" cellspacing="0"> <tr> <td class="sheet-statlabel-big" style="font-size: 1.5em;
