While developing web layouts, at some point you've probably run into the issue with the footer floating in the middle of the page just below the content. This can easily be fixed with a little CSS magic. Service Portal does support fixed headers and footers, but this causes the footer to stick to the browser window and overlap the content, which is not what we want. We want the footer to always be at the bottom of the page. This is called a "sticky footer". In between Helsinki and Istanbul some major changes were to made to the outer page structure that broke some earlier solutions posted on the community. My goal is to provide a solution that would work with all versions of Service Portal and it's various supported browsers. The Solution: I've chosen to implement the sticky footer using Flexbox as this provides the most amount of flexibility. One added advantage of flexbox is that it also supports variable height footers, which many other solutions do not. Installation: Go to your portals theme record. Select a footer widget, you can use the out-of-box "Sample Footer" as a test. Make sure the "Fixed footer" checkbox is unchecked. Paste the following snippet of CSS into the "CSS variables" textarea, or alternatively you can include it in a CSS Include. [crayon-5974cf6c3bdf6631754840/] It's been tested on Helsinki, Istanbul, and Jakarta using Chrome, Safari 9+, IE10+. For additional information on flexbox, you can check out the following resources: A quick guide to flexbox by CSS-Tricks - here. Solved by Flexbox, a website dedicated to cool flexbox techniques - here. I hope you've picked up something new and useful from this article.

In the stock Service Portal it asks the user "How can we help" and then provides the user with a big search input. This implies that the user could enter a sentence or phrase such as "reset my password" to answer the question, however this will rarely deliver the correct results. ServiceNow provides several search operators for performing full text searches with GlideRecord using ServiceNow's Zing search engine. However the stock widgets in Service Portal are hardcoded to use “123TEXTQUERY321” which works great for single word searches but not so much for searches containing multiple words or phrases. In this example, the simple addition of the word "my" prevented the user from finding the "Reset Password" item. To improve the search results, let’s take a quick look at some of the other options available. Search Operator Description IR_AND_QUERY Display results with exact matches of all terms only (Same as 123TEXTQUERY321) IR_OR_QUERY Display results with any matches of any terms. IR_AND_OR_QUERY First display results with exact matches of all terms, then display results with any matches of any terms Of the above, I recommend using IR_AND_OR_QUERY as this will return the best results across all combinations of searches. When performing a full text search, ServiceNow also adds an additional property to the GlideRecord called "ir_query_score" which contains the relevance score calculated by the system. Administrators can control the scoring for each field in a table with the ts_weight attribute. Here is a quick example of how to search the Service Catalog and return results ordered by relevancy: [crayon-5974cf6c3d0d9649300012/] For further reading, check out: https://codecreative.io/servicenow/gliderecord-full-text-search-explained https://codecreative.io/servicenow/how-to-do-full-text-search-with-gliderecord http://wiki.servicenow.com/index.php?title=Administering_Zing_Text_Search
If you’ve ever tried creating a dynamic link with a non-standard protocol or prefix (e.g. file, sms, tel, ftp, local) in Service Portal, you may have noticed that it prepends the url with “unsafe” rendering it unusable. The sanitization is a security measure aimed at preventing XSS attacks via html links and is coming from Angular.js which maintains a whitelist of safe urls. To fix this you will need to override the default whitelist by passing in a regular expression to the application configuration. You can do this by creating a “js_include” in your portal theme and include the following script: [crayon-5974cf6c3dc16682241477/] Where you see https?|ftp|mailto, etc… that is the regular expression you will want to update to include your url prefixes.
Included with Service Portal are a variety of different CSS utility classes loosely based on some of Bootstraps utility classes. For many of the classes below, you will see a format similar to: "m-t-lg", this stands for "margin top large". As I'm sure you can guess, there is also a classes for bottom, left, right, small (sm), medium (md), etc. and all the various combinations thereof. This allows you to easily add consistent margins, padding, colors, etc. without creating custom styles within the widget. Here is a list we've compiled of some of the most common utility classes: Padding: wrapper, wrapper-xs, wrapper-sm, wrapper-md, wrapper-lg, wrapper-xl Horizontal Padding: padder, padder-xs, padder-md, padder-lg, padder-xl Vertical Padding: padder-v, padder-v-md, padder-v-lg, padder-v-xl Top Padding: padder-t, padding-top-s, padding-top-m, padding-top-lg, padder-t-lg, padder-t-xl Right Padding: pad-right Bottom Padding: padder-b-none, padder-b, padder-b-md, padder-b-lg, padder-b-xl Left Padding: N/A Top Margin: m-t, m-t-none, m-t-xxs, m-t-xs, m-t-sm, m-t-lg, m-t-xl, m-t-n-xs, m-t-n-lg Right Margin: m-r, m-r-none, m-r-xs, m-r-sm, m-r-lg, m-r-n Bottom Margin: m-b, m-b-none, m-b-xs, m-b-sm, m-b-lg, m-b-xl, m-b-n Left Margin: m-l, m-l-none, m-l-xs, m-l-sm, m-l-lg, m-l-n Text Color: text-muted, text-primary, text-success, text-info, text-warning, text-danger Background Color: bg-primary, bg-success, bg-info, bg-warning, bg-danger Float Elements pull-left - Floats an element to the left pull-right - Floats an element to the right Clearing Floats clearfix - Clears floats Display & Margin center-block - Sets an element to display:block with margin-right:auto and margin-left:auto Visibility show - Forces an element to be shown (display:block) hidden - Forces an element to be hidden (display:none) invisible - Forces an element to be invisible (visibility:hidden). Will take up space on page even though it is invisible sr-only - Hides an element to all devices except screen readers sr-only-focusable - Combine with "sr-only" to show the element again when it is focused (e.g. by a keyboard-only user) text-hide - Helps replace an element's text content with a background image close - Indicates a close icon caret - Indicates dropdown functionality (will reverse automatically in dropup menus) Hide visible-xs, visible-sm, visible-md, visible-lg Show hidden-xs, hidden-sm, hidden-md, hidden-lg For more details on CSS in Service Portal, you can check out the unofficial documentation on Github: https://github.com/service-portal/documentation/blob/master/documentation/css.md#page
A common feature request for Service Portal is to be able to add custom buttons to the sc_request or ticket page similar to the way you could add UI actions to a form. This functionality is not available out-of-box, but here is a quick example on how you could create a custom widget to display some buttons to mimic the UI Actions on a form. In this example, we will create a "Resolve Incident" button to place on the incident "ticket" page. HTML: [crayon-5974cf6c3e040387686446/] Client Script: [crayon-5974cf6c3e048171570115/] Server Script: [crayon-5974cf6c3e04e776904813/] The resulting widget should look something like this: This is far from the complete solution, but will hopefully provide a good example to work off of.
Widget Instances are a vital component of Service Portal, and although at first glance they seem simple, they can be quite powerful when utilized correctly. In simple terms, the widget instance record stores the location of the widget (which column) and the context needed for it to render. The context of the widget is comprised of the fields on the instance table as well as the "Additional options" field in JSON format. The additional options get generated based on the fields defined in the "Options Schema" on the widget, documented here. Each widget defines which instance table it will use along with which fields from that table. To set the "table" and "fields" variables on the widget, you must open the widget record in the standard ServiceNow UI form. See the example below from the "Icon Link" widget which uses the "sp_instance_link" table. The following is the out-of-box instance tables available: Instance (sp_instance) Base instance table with the following fields: color, css, glyph, short_description, size, title, url Instance of Carousel (sp_instance_carousel) Instance primarily used by the carousel widget, has a related list of slides Instance of Simple List (sp_instance_vlist) Used by list widgets such as "Simple List" and "Unordered List" and contain fields specific to setting Tables and Filters Instance with Link (sp_instance_link) Used for creating widgets that act as hyperlinks, e.g. "Icon Link", with fields such as URL and references to commonly used tables Instance with Menu (sp_instance_menu) This is the instance used by the Header Menu (referenced from the Portal), but can also be used for any widget displaying a menu. It has a "Menu Items" related list. Instance with Table (sp_instance_table) The instances behind the Data Table and Count widgets, with fields for setting the Table and Filter You can also create your own Widget Instance table by extending "sp_instance" and referencing the new table and fields in a widget. If the table referenced on the widget is changed, it will NOT automatically update the existing instances, so you will need to remove the old instances and generate the new instances via the Service Portal Designer. Once completed, you will now see your custom instance fields when you view the widget Instance Options (CTRL + Click > Instance Options).
In Service Catalog you have the ability to embed a UI Macro as a variable in your catalog items or record producers. UI Macros are based on Jelly and as such they will not render in Service Portal. To work around this, you can now embed a widget for your UI Macro variables when displaying your catalog in Service Portal. In this example, we're going to create three variables, and make the third variable a widget that will display the sum of the other variables. Create a catalog item with the following variables: Single Line Text: "value1" Single Line Text: "value2" Macro: "results" On the "results" variable record, you will see a "Default Value" tab, with a reference to the Widget. Create and select a new widget called "Embedded Results", and use the following values: HTML: [crayon-5974cf6c3f876662627791/] Client Script: [crayon-5974cf6c3f87e800437988/] Now when you view this catalog item in the portal, the embedded widget will display the results of the two variables: Note, that the "field.change" event fires when the field loses focus, so you will have to tab or click out of the field to see the results.
An issue I have come across in the past is keeping track of all the small CSS color changes etc. Fortunately, Service Portal supports the use of SCSS variables in the widget CSS. For example, instead of using CSS to define a color in every widget, set the dynamic Bootstrap variables in your Service Portal theme. You can also create your own custom variables to use in specific projects; i.e. $favorite-color. Here is an example of what it would look like in the Widget CSS: Now when a color needs to be changed across multiple widgets, you can change it in a single place. Service Portal also supports other SCSS features such as the use of Nesting, Mixins, and Operators. Note: The Service Portal SCSS implementation is a subset of the full SASS specification. To view a full list of default Bootstrap variables that you can customize, visit this link. If you would like to explore more, you can view the official ServiceNow documentation.
A question that I get asked a lot is how to use custom fonts in Service Portal. Here are the three primary ways: Option 1: The easiest option is through Google Fonts. Select the Google font you want to use. Copy the font's style sheet URL. Go to your theme and add a new CSS Include. Make sure the "Source" is selected to URL and then paste the CSS URL. Click save. Now you can reference the font in your CSS. [crayon-5974cf6c406e2465137299/] Option 2: You'll need to encode your fonts using base64 and then include them in the CSS Includes of your theme. You can use this free tool by Font Squirrel: Create Your Own @font-face Kits | Font Squirrel. Use the "expert" option, then you will see an option for base64 encoding in the CSS section. Select "Base64 Encode." Once exported, add the generated code as a CSS include on your theme. For more information see: Learn how to create custom CSS in your theme here. Option 3: Another approach is to upload your font files as attachments to the CSS Includes record and then reference them with "sys_attachment.do?" and passing in the sys_id as a parameter. See the following example: For additional information on CSS fonts, here's an article that I have found to be very helpful. If you find this useful, let me know in the comments below.
