Parent/Child nested galleries height issues

I have a powerapp that has a parent/nested child gallery. Inside the child gallery I have 3 radio buttons and two labels. Radio1 determines the visibility for the other two radio and labels.  My question is can i adjust the size of the either of my galleries based on the controls visible in the child galleries.

 

I do not think it is possible but I want to ask.  Also I have created an expand/collaspe as well on the parent, I want to know if there is away to set all of them to collasped.

 

Thanks in advance.

Sure, but not directly. Just think of it this way

If I have a control [control a] and selecting option 1 on it hides [control b] and shows [control c] and opposite is true for next case etc

 

So lets say [control a] does something along the lines of OnChange 

Set(radioChoice, Self.Selected.Value)

 

Now [control b] and [control c] can both set their visibility based on the Global Variable radioChoice, and since the variable is global the parent gallery can also reference that for its height. (make sure to have an option in there for blank, or to set a default value for radioChoice variable in the app onstart or screen onvisible

I have the visibility working that is not the issue the issue is that the heigh of the galleries are not adjusting meaning if i only have one control showing the child gallery should be 60 while if a lable and another radio button is showing it should be 221, however the parent is a flexible but the child is not collasping to 60 that is the issue.

make height of gallery something like (using my example)

switch(radioChoice, Blank(), 100, "Option 1", 100, 0)

Just have to do what I said above so the radio choice becomes a global variable instead of a nested reference

I am not following to be honest what you are suggesting, because i have tried all of this but it leaves the parent gallery over 221 when only radio1 is showing. it does not reduce it down.

What is the OnChange of your radio that hides everything. (and what selection on it will hide things)

What is the Height value of the gallery you want to disappear.

I think something is getting lost in translation here.

 

I have a parent gallery with an nested child gallery I have a radio1 that will always show, however based on the selected value it will hide or show labels and additional radio buttons in the child gallery.

 

What I an trying to accomplish here is my parent gallery is a flexible gallery which is fine but based on what is showing in my child gallery I want that to shrink or expand based on radio1 value.

That big white space is the Parent gallery not shrinking up i am trying to figure out if it is even possible?
