Change the Size of a List Collector Slushbucket Variable

List collector variables are a great way to collect multiple pieces of information about referenced records in a single variable in the Service Catalog. One complaint I get about these variables is that they take up a lot of space on the screen. While there’s not a lot you can do with regular slushbuckets in the system, List Collector variables have a little bit more flexibility because they can be manipulated with client scripts. Check out the SNCGuru List Collector archives for more examples of cool List Collector modifications you can use.

In this article I’ll show you how you can reclaim some of that Service Catalog screen real estate by modifying the size of a list collector variable using a catalog client script.

ere’s a cool catalog client script that I figured out for a client. It allows you to move one or more selected options from one side of a list collector variable slushbucket to another. Using the script is pretty straight forward. Just supply the name of the list collector variable you are working with, and then make sure you provide an array of option IDs to move from one side to another. The option IDs need to be added to the ‘selectedIDs’ array in the middle chunk of code. The code below is set up to move ALL options in the right column of a slushbucket to the left.

Limiting Number of Selections in a List Collector

ist collector variables are a great way (currently the only way) to allow a user to select multiple options from a referenced table in a single variable on a service catalog item. The list collector variable allows you to choose from one to many (potentially hundreds or more) selections. What if you wanted to limit the number of items that a user could select? This script does exactly that. It restricts the selected items list on a list collector variable to whatever amount you choose. Just use the catalog client script below and set the variables for the maximum number of selections and the name of the variable to apply the restriction to.

Customizing the Slushbucket

The term ‘Slushbucket’ is used in Service-now to refer to a couple of places in the system…

  • The popup window view that you see when you click the ‘Edit’ button from a related list at the bottom of a form.
  • The interface used to display any ‘List collector’ service catalog variable

A question that comes up pretty often is “Can I customize the slushbucket to display more information about the items shown?”. The answer to this is ‘YES’ but it might not work exactly like you think it should. Currently, you only have control over the field values shown below the slushbucket when you click on any item to highlight it. The actual values shown in the slushbucket are determined by the ‘display’ field on the dictionary entry for the referenced table. Most people would like to display multiple columns worth of data for items within the slushbucket itself, but this is not possible yet.

Changing the Filter of a List Collector Variable via Client Script

f you’ve worked with the Service-now.com service catalog much, you’ve probably realized that there are some differences between the service catalog interface and the traditional forms that are used throughout the rest of the tool. The intention of this is to make the experience a little bit better for end users of the system but it also means that you, as an administrator, have to learn a few new tricks to deal with those differences.

One of these differences is the List collector variable. It allows the user to select multiple items from a list of items and optionally filter those items to help in their selection. One of the most common requests I see about this type of variable deals with how to handle the filter at the top of the list collector. Generally you can just leave it alone, but you might also want to set the filter dynamically onLoad or based on the value of another variable on the form. Depending on the situation and the number of items in the list collector table you may want to remove the filter portion completely.
