Fixed position when scrolling until a certain point

Hi Will, unfortunately, this functionality isn't yet supported.

You can make an object either fixed or scrollable, you can't add a condition that will change this setting.

I have been using sort of a workaround - I use a cover rectangle with the color of the background, and have the fixed version of the element underneath it.

Here's a quick demo with a prototype:

I made the cover a slightly different color in the second screen, so you can see it.

And here's the file, so you can see how it's set up:

It is not perfect, and not applicable for every use case, but it is enough for most of these sticky header scenarios.

Until we get it as a feature, that's the only way to sort of achieve that effect.

Update: Made a small tutorial on how to achieve this

Hope this helps.

Cheers!
