Hello, I’m using the `WhileVisibleInScrollView` tag to trigger some animations. However, I want to make it so that the trigger activates when the entire object is visible in the `ScrollView`, right now the animation is triggered when any part of the object is visible in the `ScrollView`. Is this possible? Thanks ---

Hi, the `Distance` property allows a bit of customisation, but seems that it won’t do exactly what you’re after. I suggest you take a look at [WhileVisibleInScrollView](https://github.com/fusetools/fuselibs-public/blob/master/Source/Fuse.Controls.ScrollView/Triggers/WhileVisibleInScrollView.uno) implementation, and build a similar trigger that takes into account the height of the particular element. Hope this helps! ---

I see, are you suggesting that I build something similar to `WhileVisibleInScrollView` in Uno? Can you point me in the direction of a how-to or tutorial that can show me how to do this? Thanks! ---

Yes, that is exactly what I’m suggesting. Either building a new trigger, or extending `WhileVisibleInScrollView` so that it does what you need it to do. The [Native Interop](https://www.fusetools.com/docs/native-interop/native-interop) section and its subsections should get you started. Looking at the existing code in `fuselibs-public` will help a lot too; I’m fairly certain there are other triggers that access the dimensions of a visual. ---

Hi Zia, good news! We have now implemented a `Mode` property on `WhileVisibleInScrollView` that can be either `Partial` (default) which works just as it did before, and `Full` which works as you would expect it to. This has been merged to fuselibs-public/master now, so you can get it with a local checkout of fuselibs: [https://github.com/fusetools/fuselibs-public/pull/178](https://github.com/fusetools/fuselibs-public/pull/178) There are no details on which future release of Fuse will have this in the libs bundled with the installer, so if you need it, I suggest you get that local checkout working. ---

Amazing, thank you so much. I will have a play around.
