  • 0

I’m building a UI in Google Sites using Apps Script and I am able to create a listbox. According to the documentation if you change the setVisibleItemCount to 1 it will become a dropdown box.

I have tried both 1 and 0.

Neither seems to make it a drop-down box. Using Firefox 13.0.1 to view. Have also tried Safari.

Anyone had any luck with this?

Code looks like this:

var vPanel = container.createVerticalPanel();
    //List box
    var lb = container.createListBox(true).setId('listbox').setName('listbox');

   // add items to ListBox
   for(var i=0;i<LIST_OF_PROJECTS.length;i++){
       lb.addItem(LIST_OF_PROJECTS[i]);
   }

   vPanel.add(lb);
   lb.setVisibleItemCount(1);  //supposed to make it a drop-down but doesn't

   lb.setSelectedIndex(0);

This is all inside a Google Site and the page that is being displayed is a Apps Script Page. Perhaps you are NOT using Google Sites? Above code gives me a single line but no drop down arrow.

    Could you post your relevant code please ?, It’s working for me on firefox (slightly differently), chrome & safari. (see screen cap when I click the selector, SetVisibleItemCount is 1)

    thx

    enter image description here

    EDIT : One important point : to get the list acting as a dropdown list you have to choose ‘disable multiple selection’, in other words : createListBox(false) or no parameter… but not ‘true’ as it is in your code !! (now we know why it doesn’t work in your case 😉

    With this parameter set to false , it works as expected in standalone webapp, embedded on site and linked to spreadsheet without any difference.
