Expand/Collapse for repeating gallery

[Anonymous]

Hi all!

I have a repeating gallery (for a timecard) and I'm trying to expand/collapse some of the items in my gallery when I click a button. The only issue I'm running into is when I 'repeat' the gallery it's expanding/collapsing everything instead of the specific items relevant to that submission. 

As you can see in the picture, I want to expand/collapse each individual entry instead of all of the entries. The issue is I'm not sure how to set the visible property EACH SPECIFIC CONTROL instead of all the controls. 

Any help is greatly appreciated! 

Thank you!

Option 1

you could group all the controls you want to expand/collapse. On the groups visible property you should use

varShowControl

on the button OnSelect property use

Set(varShowControl,!varShowControl)

 I've wondered about this before. You can show or hide controls per item but afaik there is no way to have a gallery with varying heights per item.

I'm running into the same issue - it expands and collapses all groups instead of just for each specific entry.

@sopatte that's not true.

Steps to build something like you require:

1. Use a Gallery "Blank flexible height"

2. Try to build something like I did. Have a look at the tree view

3. To Group controls you just select all controls you want to group, left cklick and Group

4. Select the group and use this for the OnVisible property

ThisItem.ID = varItemID

5. On the button OnSelect use

Set(varItemID,ThisItem.ID)

Play the app and test it

Please keep in mind that there is no such thing as a "Group" in PowerApps.  When you Group your controls, you are just grouping them together in a convenient way.  So, while you think you might be setting the Visible property of the "Group" to something, you are really setting the Visible property of ALL the controls inside the group.  This is an important distinction!

@Anonymous your issue is that you are trying to use a single variable to expand and collapse multiple rows of multiple records.  So, in a sense, you would need multiple variables.  That is not practical in PowerApps this way.  So utilizing a more elaborate variable or a collection (in-memory database) to determine expansion/collapse is needed.

I am not seeing what it is that you want to expand or collapse as per the record/row of the gallery.  Your expand collapse is outside of the gallery, so it is assumed that you DO want to expand and collapse all items.

As for the spacing in the gallery - you need to use a Flexible Height gallery for what you are trying to do.

I hope this is helpful for you.

Hey Randy! So I have a collection taking in all of these values.

The reason the expand/collapse button is currently OUTSIDE of the gallery is because I couldn't get the expand/collapse function to work inside of the gallery. That being said I'm trying to move it into the gallery to make it work.

What I was initially trying to do was to make the onvisible property look like this:

Set(VarShowID, Sum(COLLECTION,ThisItem.ID)) and then the visible property for the controls (I.E. the group) was if(varShowID=Sum(COLLECTION,ThisItem.ID),true,false). I still am running into the issue of EVERYTHING expanding/collapsing instead of just the specific entry. 

Also, see the image below for what I am attempting to make visible/unvisible. Thank you!

@RandyHayes You are totally right and I am absolutely aware of that. But to keep life easier I thought using a group here would make sense. 🙂

It was true given the qualifier "afaik" :D. I didn't know about the flexible height gallery. I'm glad to know about it now.

Groups are just fine (although annoying at times), but the common misunderstanding is that the "Group" is a control by itself that has a Visible, OnSelect, etc. on it...It does not, it is just a convenience to select a group and set a Visible, but it is NOT setting a Visible on a "Group" it is setting the visible on ALL of the control in the group.  

The annoying part is that you can easily destroy existing formulas with that process.  So, if you had a control with a formula in the Visible property and then you grouped it with others and then set the Visible property on the "group" then you will be wiping out the existing Visible property on that particular control.

But in the case of the gallery "real estate", even grouping them will not cause the gallery to change height unless it is in a flexible gallery.
