Ionic Framework Version

• [ ] v4.x

• [X] v7.x
• [ ] Nightly

Current Behavior

1. Input in the middle of a 100%+ tall screen:

Focusing works well, blurring doesn't change the position

2. Input at the end of a 80% tall screen

Focusing doesn't work at all, blurring jumps back into previous position (instead of smooth scroll)

3. Input at the end of 100%+ tall screen

Focusing works well, blurring jumps back to position (instead of smooth scroll)

Expected Behavior

All animations should work just like the system animation, shown here:

---

• Focusing: Scrolling should start on tap, simulatenously with the keyboard animation
• Blurring: When user taps outside the field, it should animate back to the previous position, simulatenously with the keyboard animation

Steps to Reproduce

Create a simple page with a few spacer elements, and input, as shown here: https://github.com/vojto/ionic-input-repro/blob/main/components/AppShell.jsx#L39-L63

Thanks for testing Ionic 7! I can reproduce this behavior. Can you give this dev build a shot, and let me know if it resolves the issue?

npm install @ionic/core@7.0.0-dev.11676564756.14eccca7 @ionic/react@7.0.0-dev.11676564756.14eccca7 @ionic/react-router@7.0.0-dev.11676564756.14eccca7

That's much better.

It still doesn't animate on blur, just jumps back into position. I'm assuming that would be too complicated to implement?

When the input is blurred we removed the padding-bottom on the .inner-scroll element which does not have a transition by default. You could try adding a transition, but it might look a bit janky:

ion-content::part(scroll) {
  transition: padding-bottom 1s ease-in-out;
}

Thanks for the issue. This has been resolved via https://github.com/ionic-team/ionic-framework/pull/26810, and a fix will be available in an upcoming release of Ionic Framework. I focused on getting parity with what happens in Ionic v6, so there is no padding transition on blur. However, you can use the code snippet above if you would like to test the transition in your app. Let me know if you have any questions.
