Quickie: Resizing a value prompt list

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.
This prompt is taking far too much room.

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)

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.
