Fix ix-tabs Scroll Issue in Small Dialogs | Siemens iX

Hey guys! Let's dive into a peculiar issue some of you might've encountered while using Siemens iX, specifically with the <ix-tabs> component. We're talking about a situation where the active tab mysteriously scrolls out of view when you're working with smaller dialogs. Don't worry; we're here to break it down and understand what's happening!

Understanding the Issue

So, here's the deal: when you're rocking a modal or dialog with a width around 600px and you've got a bunch of <ix-tab-item> elements inside your <ix-tabs> (enough to get that horizontal scroll going), clicking on the first tab (or the one right next to it) can cause the active tab to scroll away and hide itself. It's like a magic trick, but not the good kind!

The Problem in Detail

Let's get into the nitty-gritty. Imagine you've set up your modal, added your tabs, and you're ready to navigate. You click that first tab, expecting it to stay put, but whoosh, it scrolls right out of view! This behavior, while annoying, seems to be specific to these smaller dialogs. Interestingly, the same setup works perfectly fine in full-width modals, where the active tab stays visible like it should. This discrepancy is key to understanding the root cause and finding a solution.

Why This Happens

Now, you might be wondering, "Why does this even happen?" Well, it boils down to how the scrolling behavior is handled within these confined spaces. In smaller dialogs, the automatic adjustment to keep the active tab in view seems to falter, leading to this unexpected scroll-away. The component isn't correctly calculating the visible area and adjusting the scroll position accordingly. This is where we need to focus our attention to ensure a smooth user experience.

Expected Behavior vs. Reality

What we expect is pretty straightforward: the active tab should remain visible after being clicked. The scroll should automatically adjust so that the active tab stays nicely in view, allowing users to easily see and interact with the selected content. This is crucial for usability, especially in applications where tabs are used for primary navigation or to display different sets of information.

Prerequisites and Environment

Before we go deeper, let’s make sure we're on the same page regarding the setup. If you're facing this issue, chances are you've already ticked these boxes, but let’s confirm:

  • Contributing Guidelines: You've read the Contributing Guidelines. This is always a good first step to ensure you're following best practices and understand the project's expectations.
  • No Leaks: You haven't accidentally shared any internal or restricted information (like screenshots or code snippets). Keeping sensitive data secure is paramount.

Frontend Framework Details

This particular issue has been observed in an Angular (Standalone) environment. Knowing the framework helps us narrow down the potential causes and solutions. Different frameworks handle DOM manipulation and scrolling in their own ways, so this context is crucial.

Version Information

Specific versions matter! This problem was reported on:

  • @angular/core: Version 20.0.0
  • iX: Version v3.2.0

If you're experiencing this, check your versions to see if they align. It's possible that later versions may have addressed this issue, or that it's specific to this combination of versions. If you're on an older version, upgrading might be a solution, but always test thoroughly in a development environment first!

Reproducing the Issue: A Step-by-Step Guide

Okay, let's get practical. If you want to see this issue in action (or confirm that you're experiencing the same problem), here’s a step-by-step guide:

  1. Create a Modal/Dialog: Start by creating a modal or dialog. Make sure to set its width to around 600px. This is the key dimension that triggers the issue.
  2. Add ix-tab-item Elements: Inside the <ix-tabs> component, add several <ix-tab-item> elements. You’ll need enough tabs to enable horizontal scrolling. Think of it as setting the stage for the problem to occur.
  3. Click the First Tab: Now, the moment of truth! Click on the first tab or the one immediately next to it. This action should trigger the scrolling issue.
  4. Observe the Behavior: Watch closely. You should notice that the active tab scrolls away, disappearing from the visible area. This is the issue we're tackling.

By following these steps, you can reliably reproduce the issue and ensure that any proposed solutions are indeed effective. Reproducibility is crucial for debugging and fixing any software problem.

Diving Deeper: Why Does This Happen and How Can We Fix It?

Alright, guys, let's get into the meat of the issue and explore why this is happening and, more importantly, what we can do about it. We've already established that the active tab scrolls out of view in smaller dialogs, but what's the underlying cause?

Understanding the Root Cause

At its core, this issue likely stems from how the <ix-tabs> component calculates and manages its scroll position within a constrained space. When a tab is activated, the component needs to ensure that the active tab is visible within the viewport. In full-width modals, there's ample space, and the component can easily adjust the scroll position. However, in smaller dialogs, the limited width introduces a challenge.

The component's logic for adjusting the scroll position might not be correctly accounting for the reduced viewport size. It might be using a fixed offset or calculation that works well in larger containers but fails in smaller ones. This discrepancy can lead to the active tab being scrolled too far, effectively pushing it out of view.

Potential Culprits: CSS, JavaScript, or a Combination?

The cause could lie in a few different areas:

  • CSS: The component's CSS might be inadvertently contributing to the issue. For example, if there are fixed margins or padding that don't scale correctly with the container size, it could throw off the scroll calculations.
  • JavaScript: The JavaScript logic responsible for handling tab activation and scroll adjustment is a prime suspect. If the calculations for determining the scroll position are flawed, it could lead to the observed behavior.
  • Combination: It's also possible that the issue is a combination of both CSS and JavaScript. The CSS might define the layout and dimensions, while the JavaScript handles the dynamic scroll adjustments. A mismatch between the two could be the culprit.

Investigating the Code

To pinpoint the exact cause, we'd need to dive into the component's code. This would involve examining the CSS rules that govern the layout of the tabs and the JavaScript code that handles tab activation and scroll adjustments. Debugging tools, such as browser developer consoles, can be invaluable in this process.

We'd want to look for things like:

  • Scroll Position Calculations: How is the component calculating the scroll position to bring the active tab into view?
  • Viewport Size: How does the component determine the available viewport size within the dialog?
  • CSS Overrides: Are there any CSS rules that might be interfering with the component's layout or scroll behavior?

Possible Solutions and Workarounds

Once we've identified the root cause, we can start exploring solutions. Here are a few possibilities:

  1. Adjust Scroll Calculations: If the issue lies in the JavaScript, we might need to refine the scroll position calculations. This could involve taking into account the actual width of the dialog and the tab, ensuring that the active tab is always brought into view.
  2. CSS Tweaks: If CSS is a contributing factor, we might need to adjust the component's styles to better handle smaller containers. This could involve using relative units (like percentages) or media queries to adapt the layout to different screen sizes.
  3. Viewport Detection: The component might need to more accurately detect the available viewport size. This could involve using JavaScript to query the dimensions of the dialog and adjusting the scroll behavior accordingly.
  4. Workarounds: In the short term, there might be workarounds we can implement. For example, we could add a small amount of padding to the left of the tabs or adjust the scroll position manually after a tab is activated.

Providing a Code Example

Unfortunately, the original report didn't include a code example to reproduce the issue directly. However, the steps to reproduce provided earlier can help us create a minimal example. A code snippet that demonstrates the problem would be incredibly valuable in finding a solution.

<!-- Example Code (Conceptual) -->
<div class="dialog" style="width: 600px;">
 <ix-tabs>
 <ix-tab-item>Tab 1</ix-tab-item>
 <ix-tab-item>Tab 2</ix-tab-item>
 <ix-tab-item>Tab 3</ix-tab-item>
 <!-- ... more tabs ... -->
 </ix-tabs>
</div>

This is a simplified example, but it captures the essence of the problem: a set of tabs within a dialog with a limited width. A more complete example would include the necessary Angular components and styles to fully demonstrate the issue.
