Hi, I have a template: The first part is a form with a drop down list. The second part of the template consists different tabs. By selecting from the list, it shows different content in the second part of the template. But I want to change the drop down list content when switch between tabs. How can I do it? The simplified version of the codes look like: <div class="panel"> <h3 >Select a tissue specific analysis: </h3> <div class="filt_options"> <form action=“/someaction/&" method="post" autocomplete="off"> <select name="tissue" class="tissue_selector"> <?pl foreach my $tissue ( @$tissues ){ ?> <option value="[== $tissue->[1] =]"> [== $tissue->[0] =]</option> <?pl } ?> </select> </form> </div> <div class="sub_data" id="tissue_selection”> <ul class="tabs"> <li><a href="#t_first">Overview</a></li> <li><a href=“#t_second”>Plot</a></li> </ul> <div id="t_first" class=“overview”> </div> <div id=“t_second” class="plot"> </div> </div> </div> Many thanks, Wendy
