UI5 Web Components v2.25.0: What the New InputIcon & Dialog Fullscreen Toggle Mean for Your Codebase
Dr. Sarah Chen breaks down two long‑awaited features – and why this release is a safe, additive upgrade for teams already on the v2 track.
If you’ve been patching icon placement inside <ui5-input> with brittle CSS or rolling your own fullscreen dialog buttons, stop. Release v2.25.0 delivers clean, official components: <ui5-input-icon> and a showFullscreenToggle property on <ui5-dialog>. Over my 16 years spanning SAP BTP, S/4HANA, and UI architecture, I’ve seen how small, additive improvements like these eliminate entire classes of support tickets. Let’s dissect what’s changed, where the sharp edges remain, and how to adopt it with minimal risk.
The Real Story
The headline is simple: two new capabilities, no breaking changes. That alone makes this release attractive for enterprise teams that dread regression testing. Under the hood, the UI5 Web Components team has formalised two patterns that developers have been hacking together for years.
<ui5-input-icon> – Icons Inside Inputs Without the Pain
Previously, slotting an icon into an <ui5-input> required custom <span> elements, absolute positioning, and a prayer that the browser’s input-field internal padding wouldn’t clash. The new component is straightforward:
<ui5-input placeholder="Search...">
<ui5-input-icon slot="icon" name="search" clickable></ui5-input-icon>
</ui5-input>
The slot="icon" keeps it inside the input’s rendering boundary, and the component handles focus, hover states, and accessibility – things that home-grown CSS almost always misses. The clickable property also fires a standard click event, so you can trigger search, clear, or dropdown actions without wiring up inline handlers.
Sharp edge: The icon is currently limited to the beginning of the input field (the icon slot). If you need a trailing icon (e.g., a clear button), you’re still off‑road. In my experience, that’s the more common pattern for date‑picker and select‑like inputs. Expect community pressure to introduce a trailingIcon slot in a later release.
showFullscreenToggle – Finally, Native Fullscreen in Dialogs
Large datasets in a dialog – think pivot‑grids, complex forms, or rich‑text editors – have always forced users to awkwardly resize the window or squint at a cramped view. With v2.25.0, you can add a built‑in toggle:
<ui5-dialog header-text="Quarterly Report" show-fullscreen-toggle>
<!-- heavy content -->
</ui5-dialog>
The button appears in the dialog header, right next to the close icon. Toggling expands the dialog to the viewport, just like a native fullscreen API. It’s clean, it’s consistent, and it removes the need for the custom maximise/minimise buttons I’ve seen in at least 40% of Fiori‑like projects.
Important caveat: The fullscreen behaviour simply stretches the dialog to 100vw/100vh and adjusts the header and footer. It does not use the browser’s Fullscreen API, so there’s no escaping the parent frame if you’re inside an iframe or a container with a stacking context. For dashboard‑style apps, this is exactly what you want. If you need true cross‑document fullscreen, you’ll still have to call element.requestFullscreen() yourself – and that remains out of scope for the web component.
What This Means for You
If you’re already on UI5 Web Components v2.x, this upgrade is a no‑brainer: bump your dependency, review the two new features, and start deprecating your custom workarounds. The risk is near zero because the release contains no breaking changes – you can literally just swap the version number in your package.json.
For teams still on v1 or classic SAPUI5, this release highlights the growing maturity gap. The web‑component library is now receiving the “quality‑of‑life” improvements that make day‑to‑day UI development frictionless. If you’re planning a new BTP‑centric project (e.g., a standalone Fiori app using SAP Build Work Zone, standard edition), I’d strongly recommend starting with UI5 Web Components and skipping the older UI5 stack unless you have legacy controls you cannot replace.
Security note: Input icons that reveal sensitive data (e.g., show‑password toggles) must be handled with care. The component itself does not sanitise or mask your logic – that’s still your responsibility. Never trust a visual “eye” icon alone; always wire it to a secure state variable in your model.
Action Items
- Migrate all custom input‑icon hacks. Search your codebase for
position: absolute,z-indexhacks inside<ui5-input>containers. Replace with<ui5-input-icon>where it fits the beginning‑of‑input pattern. For trailing icons, log a feature request but don’t block the upgrade. - Audit all dialogs that display complex content. Add
show-fullscreen-toggleto every<ui5-dialog>that holds a table, chart, or form longer than a screenful. No extra logic needed – it’s a one‑property flip. - Update your theming. The new icon inherits from your active theme, but if you’ve heavily customised the input background or border, verify that the icon remains visible. A quick test in your design system’s storybook takes five minutes.
Community Perspective
Early feedback from GitHub and the SAP Community shows that the fullscreen toggle solves a real accessibility issue: users on smaller screens or with zoomed‑in UIs can now view complex dialogs without losing context. The input icon also earned praise for reducing the CSS‑maintenance burden. The only grumble – the lack of a trailing‑icon slot – is already being discussed on the open‑source roadmap. That kind of iterative progress is what makes the web‑components ecosystem healthy.
Bottom Line
UI5 Web Components v2.25.0 is a textbook “boring” release: additive, specific, and instantly useful. That’s exactly what enterprise developers need. Upgrade now, delete some CSS, and enjoy a cleaner, more accessible UI – all with no regression risk. When the trailing‑icon slot arrives (and I’m sure it will), we’ll have an even stronger story. For today, this is a win.
