Decision tree - page snaps to top if a user scrolls

Squiz Matrix Support

I’m using a decision tree and am running into an annoying issue.

When a user scrolls the page and answers a question, the page then snaps back to the top, meaning a user then has to scroll down again to answer the next question or see the answer. If a user just selects answers to questions as they appear on the page, there’s no issue, only when they scroll down themselves.

Is this a Squiz bug?

Shouldn’t scroll you up.

Are there any JS errors that get thrown when this happens?

Is it a public decision tree you can share the link to?

Also, what version of Matrix?

I’m using 5.4.5.1 and I’m not seeing any JS errors. It’s under construction at the moment.

I can’t replicate it, so it might be something specific to your implementation on the frontend. Perhaps some other JS in your page design is interfeering with it?

Maybe try using a brand new decision tree and using a basic design to see if you can replicate it there?

Alternatively, if you are a Squiz client, I’d recommend sending a support ticket in so that Squiz support can have a closer look and try and fix/diagnose.

Thanks. I’ve sent a ticket

So, running into this same issue again. The page snaps to the top when a user scrolls down while they’re working through the tree. If the bookmarks aren’t visible on screen, then the page snaps up. See: https://www.monash.edu/fees/other-costs/amenities/ssaf-calculator-2020-and-2021

The issue seems to only occur on radio buttons, as changing a value in the select box doesn’t have the same effect.

V.5.5.6.3

So it turns out by changing the styling of the radio buttons, this issue gets resolved. Clearly a bug though.
