While ServiceNow doesn't have native support for the position: sticky property within Service Portal pages, here are effective workarounds to achieve a similar sticky behavior:
1. Using position: fixed with Careful Positioning:
Apply position: fixed to the element you want to stick.
Adjust top, left, right, or bottom properties to position it within the viewport.
Important: Use z-index to control stacking order and prevent overlapping with other content.
Considerations:
Fixed elements can cover other content when scrolling.
Requires precise positioning to avoid unwanted behavior.
Example:
CSS
.sticky-element {
position: fixed;
top: 10px; /* Adjust as needed */
left: 0;
width: 200px;
z-index: 10; /* Ensure it's above other content */
}
2. Using JavaScript for Dynamic Stickiness:
Implement JavaScript code to track scroll position and dynamically adjust the element's position when a certain threshold is reached.
This provides more control and adaptability.
Example:
JavaScript
window.addEventListener('scroll', function() {
const stickyElement = document.querySelector('.sticky-element');
const scrollPosition = window.scrollY;
if (scrollPosition >= 100) { // Adjust threshold as needed
stickyElement.style.position = 'fixed';
stickyElement.style.top = '0';
} else {
stickyElement.style.position = 'static'; // Or 'relative', depending on your layout
}
});
3. Utilizing Theme Options for Fixed Headers/Footers:
If you need a fixed header or footer, explore theme options within ServiceNow.
Some themes offer built-in settings for fixed headers and footers.
4. Exploring Third-Party Libraries (If Allowed):
Consider using third-party sticky element libraries if your organization permits them.
Research compatibility and potential performance implications.
