Another problem from a reader. Unlike checkbox or radio prompts, list prompts don’t expand and collapse to fit the number of options available to them.

In the above image, we have a prompt that has too much space. Let’s shrink that down.

Now it shrinks to the number of rows displayed, or expands to a maximum of 15 items.

It’s actually a very easy script. The first step is to identify the prompt. We’ll use the old fW script (so this should work in every since 8.4).

var fW = (typeof getFormWarpRequest == "function" ? getFormWarpRequest() : document.forms["formWarpRequest"]);
if ( !fW || fW == undefined)
{
  fW = ( formWarpRequest_THIS_ ? formWarpRequest_THIS_ : formWarpRequest_NS_ );
}
var preFix = "";
if (fW.elements["cv.id"])
{
  preFix = fW.elements["cv.id"].value;
}
var nameSpace = "oCV" + preFix;

Next, we need to identify the prompt object:

var pr = fW._oLstChoicesPromptName;

The prompt itself is a standard SELECT element. We can set the size attribute to easily set the height.

This gives us:

if  (pr.options.length>15)
{
  pr.size=15
}
else 
{
  pr.size=pr.options.length
}

The following report XML is based on 10.2.1, but you can downgrade it easily by changing the schema number on the first line.
