Hi,

I have two galleries. Gallery 1 contains a list of 5 items. Gallery 2 contains the details of each item from Gallery 1.

I would like to position the location of Gallery 2 right next to the selected item from Gallery 1 (i.e. dynamic Y based on the selected item from Gallery 1).

Doable?

Hi @karimabdelrazek ,
Firstly, the Selected Item of a gallery does not have a Y Property.
Depending on the possibility if this going off the screen, it would be (sort of) achievable by collecting the first list
ClearCollect(colFirstList, FirstList)
Adding a number column to it
Clear(colYRef); ForAll( colFirstList, Collect( colYRef, Last( FirstN( AddColumns( colFirstList, "RowNo", CountRows(colYRef) + 1 ), CountRows(colYRef) + 1 ) ) ) )
Then setting base the First list on colY and the Y of the second list to something like
(colY.Selected.RowNo * Gallery2.TempleSize) + Gallery2.Y
I have not tested any of this - it is a concept.

Hi @karimabdelrazek ,
I have just tested it and this works (except as I mentioned, it can go off the screen if your numbers are big enough)
Gallery1.Selected.RowNo * Gallery1.TemplateHeight + Gallery1.Y

Hi @karimabdelrazek ,
A bit of fine-tuning - I am actually going to use this myself. This will line the second gallery up exactly with the top of the selected item on the first on every selected item.
Gallery1.Selected.RowNo * (Gallery1.TemplateHeight + Gallery1.TemplatePadding) + Gallery1.Y - Gallery1.TemplateHeight

Hi there,
I am having a similar issue, but I'm a beginner in PowerApps. I would need exactly the output that @WarrenBelz posted. However, I cannot make my second gallery to show only the items that the user chose/clicked on from the first gallery.

Longer description:
Gallery A has software names (Items = taken from SP list), Gallery B has license types names (taken from another SP list). I would need for Gallery B to do what it's showed above in the gif: to show a list of license types based on the user selection (I need to record that afterwards).
I cannot make the Gallery A arrows clickable (nothing happens) and neither Gallery B to show dynamic content.
May you please help with what code to put where? I tried Filtering and others but nothing worked so far.

Many thanks!

Hi I made a variable onStart Set(varVisible; True) and then set the OnSelect on the Arrow to Set(varVisible; !varVisible). Then you need to set the Visible property on the Gallery B to varVisible
