Psycho Posted May 28, 2010 Share Posted May 28, 2010 I would just build all of the checkbox lists and then use style properties to show/hide the appropriate lists. Example: <html> <head> <script type="text/javascript"> function showList(selectObj) { var lists = new Array('cars', 'computers', 'sports'); var selectedListID = selectObj.options[selectObj.selectedIndex].value; var divObj; for(i=0; i<lists.length; i++) { divObj = document.getElementById(lists[i]); divObj.style.display = (selectedListID==lists[i]) ? '' : 'none'; } return; } window.onload = function() { showList(document.getElementById('listType')); return; } </script> </head> <body> <select name="listType" id="listType" onchange="showList(this);"> <option value="cars">Cars</option> <option value="computers">Computers</option> <option value="sports">Sports</option> </select> <br /> <div id="cars"> <input type="checkbox" name="cars[]" value="Honda"> Honda<br /> <input type="checkbox" name="cars[]" value="Ford"> Ford<br /> <input type="checkbox" name="cars[]" value="Toyota"> Toyota<br /> </div> <div id="computers"> <input type="checkbox" name="computers[]" value="Dell"> Dell<br /> <input type="checkbox" name="computers[]" value="HP"> HP<br /> <input type="checkbox" name="computers[]" value="Alienware"> Alienware<br /> </div> <div id="sports"> <input type="checkbox" name="sports[]" value="Football"> Football<br /> <input type="checkbox" name="sports[]" value="Basketball"> Basketball<br /> <input type="checkbox" name="sports[]" value="Baseball"> Baseball<br /> </div> </body> </html> Quote Link to comment Share on other sites More sharing options...
