We've had a number of clients ask about structuring catalog item forms as more of a "wizard" that only renders one section at a time. After thinking about it for a while, I realized that I could use the GlideForm API to programmatically hide and show the different sections (containers). So over the past couple of weeks, I've been working on a new widget that simply interacts with the out-of-box catalog item widget, and uses the API's to add all of the wizard-like capabilities. I think it turned out pretty cool, it's fully themeable, and best of all, it does not require cloning of any widgets. I still have a few more features to add, and I'm also considering adding an accompanying library of Variable Sets that provide a more graphical UI than the out-of-box catalog variables. If all goes well, I may end up including the widget in our RocketFuel library of widgets, so if you're interested in adding some wizard-like capabilities to your portal, feel free to contact me and we can schedule a demo. I'd love to hear what you guys think in the comments below. Is this a useful widget? Does this improve the user experience of the service catalog item form?
Today I am going to show you how to change the styling of the built-in notifications in Service Portal. The default notifications in Service Portal are based on the Bootstrap Alerts components, but I prefer the smaller "Toast" notifications of Bootstrap 4. Default New Style The following CSS sets a new width and aligns the notifications in the upper right corner of the screen rather than spanning the whole page. You will need to add the following styles into a CSS Include in your theme. CSS [crayon-5d593d0c5dce3090112365/] If you are already on the Madrid release, I recommend replacing the above HEX colors with the $brand-success and $brand-danger variables so that they can be driven by the variables defined on your theme. If you wish to trigger notifications from your own widget, you can trigger notifications using either of the following. Server Side: gs.addInfoMessage("Success goes here"); gs.addErrorMessage("Error goes here"); Controller: spUtil.addInfoMessage("Success goes here"); spUtil.addErrorMessage("Error goes here"); BEFORE AFTER This is just a small example of how you can restyle the default notifications, but there is still plenty of ways this could be improved. If you have some ideas or other styles that you would like to share, feel free to post them in the comments below.
By now, you've probably already used the Simple List widget. It is one of the default widgets on the OOB portal homepage. Similar to the Data Table widget, it is used to display a list of records from a table. However, there is a lot more to this widget than you might think. In this post, we will cover some of the secrets of the simple list widget. To give you a quick sample of its capabilities, there is an OOB demo page available at: https://yourinstance.service-now.com/sp?id=test_list Features Include: Display records from any table and filter Support for image fields Show primary and multiple secondary fields Limit the height with scrollable body Trigger an event Customizable actions To get started, let's first create a widget which shows the payload of the event that get's triggered when clicking a record. HTML: [crayon-5d593d0c61174002970208/] Client Script: [crayon-5d593d0c6117d999857754/] Now if you place this widget on the same page as the Simple List widget, and if you don't specify a "Link to this page" in the Instance Options, you will see the JSON representing the record you clicked on. With this event, it'll be very easy to trigger a modal window or other user interaction, but for now let's proceed to adding some List Actions. LIST ACTIONS The Simple List widget supports adding additional actions for the records in the list. For some reason this related list is not visible on the form by default, so we'll need to add it: Pull up the Platform View of the Instance Record of the Simple List Click the hamburger icon > “Configure” > “Related Lists” Add "List Action -> Parent List" Now you should see the List Actions Related List When adding List Actions, you are able to include properties from the record in the URL field using double brackets: [crayon-5d593d0c61184080384117/] However, there are a couple of unfortunate limitations: You cannot link to an external URL You cannot use URL prefixes such as “mailto:” or “tel:” Clicking a List Action does not trigger an event This limits the List Actions to just linking to other pages, but hopefully this will get fixed in an upcoming release. DEMO Here is a quick video demonstrating how to configure some List Actions on the Simple List widget.

Learn how to streamline your stylesheets in Service Portal by utilizing the full power of SCSS. In this tutorial, I'll walk you through how to use CSS Variables in your widgets, so that they can be overridden in the Theme and Portal records. This is very useful when creating highly reusable widgets, themes or in situations where you have multiple portals sharing a theme. SCSS is a subset of the Syntactically Awesome StyleSheets (Sass) specification and is an extension of CSS. Every valid CSS stylesheet is valid SCSS. SCSS supports the following: Variables Variables are a way to store information that you want to reuse throughout your stylesheet. You can store things like colors, font stacks, or any CSS value you think you want to reuse. SCSS uses the $ symbol to make something a variable. Nesting SCSS lets you nest your CSS selectors in a way that follows the same visual hierarchy of your HTML. Operators SCSS has a handful of standard math operators like +, -, *, /, and %. Mixins A mixin lets you make groups of CSS declarations that you want to reuse throughout your site. You can pass in values to make your mixin more flexible. Functions SASS supports the use of functions by providing some keyword arguments, which are specified using normal CSS function syntax. Quick note: The order of CSS that is shown in the video is based on the Kingston release. In Jakarta, the Theme variables were loaded before the Portal variables.

How do you go from hacking a widget together to creating one that is maintainable, easy to understand and performant? You accomplish a lot with Service Portal widgets with a little knowledge of ServiceNow APIs and Angular.js, but too often widget client and server scripts become long and overly complicated. In this session, you will learn practical techniques to make your controller and server scripts more maintainable, flexible and powerful by embracing good coding practices, encapsulation, and decoupling.

Due to popular demand, here is a quick video highlighting the portal and some of the widgets we showed during our CreatorCon sessions at Knowledge18. We've made the following widgets and applications available for download: Gamification for Service Portal https://serviceportal.io/gamification-in-service-portal/ Unlocking Service Portal Widgets https://serviceportal.io/downloads/k18-creatorcon-example-widgets/ If you've found this content useful or if you have any special requests for upcoming posts, please let me know in the comments below.
