    resolved [RESOLVED] Chained Select, but for a checkbox?

    Ok, so I have a drop-down select menu to select "which company" is responsible for a given project... but if a certain one is selected, I need it to offer a checkbox that says something like "this company only?" ... currently we're only working with 1 company that needs this checkbox, because the rest of the companies we work with, we handle all of their business.

    Any suggestions?

    Exclamation

    Sort of like that, yes, but the options' values have to be the ID-numbers of the companies

    Alternative solution (because I'm such a slow typist!)
    Code:
    <!DOC HTML>
    <html>
    <head>
    <style>
    #cb {display:none}
    </style>
    <script type="text/javascript">
    //<![CDATA[
    function selectCompany(info) {
      var tarr = info.split(':');
      document.getElementById('cb').style.display=tarr[0];
      alert(tarr[1]);  // save or return value is necessary for later use elsewhere
    }
    //]]>
    </script>
    
    </head>
    
    <body>
    
    <select onchange="selectCompany(this.value)">
    <option value="none:"> please select </option> 
    <option value="none:Company 1">  company 1 </option>
    <option value="block:Company 2"> company 2 </option>
    <option value="none:Company 3">  company 3 </option>
    </select>
    <div id="cb"><input type="checkbox"/>Just this one?</div>
    
    </body>
    </html>
