I have this drop-down list that works successfully, when someone wants to search by keyword, channel or All. I'd like to add the ability where someone can search by sub-channel. <form method="get" action="../search.php" name="myForm" /> <input autocomplete="off" id="keyword" name="keyword" value="SEARCH WORDS" onfocus="if (this.value=='SEARCH WORDS') {this.value=''; this.style.color='#696969';}" onclick="clickclear(this, 'Search [var.site_name]')" onblur="clickrecall(this,'Search [var.site_name]')" value="" /> <select size="1" name="type" class="dropdown_box" /> <option value="All">All Videos</option> <option value="1">Channel-1</option> <option value="2">Channel-2</option> <input type="submit" value="VIEW"/> </div> </select> </form> Code (markup): A user/uploader can upload a video to a channel, and select a sub-channel, but currently can't search by sub-channel. How can I add code so that someone can select a sub-channel under each channel? Thanks for any help.
