Summary
In this blog post, I share the steps for creating an expand-collapse gallery control in the PowerApps Canvas App.
Now, let’s start building the Gallery, for which we would have to create our list first and have the same loaded in a PowerApps App as a data source.
Step-1
Create “Expand-Collapse Control” list with the following columns and their types
Step-2
Add a few entries in “Expand-Collapse Control” list
Step-3
Create a Canvas App and name it “Expand-Collapse App”
- Add a new Blank screen
- From the Controls section on the top in Insert tab, add a “Blank flexible height” gallery – which would be our Parent Gallery
- And add a “Blank vertical” gallery in “Blank flexible height” gallery – which would be our Child Gallery
- Parent Gallery
- Child Gallery
Step-4
Adding the data source to Gallery
In the Parent Gallery add “Expand – Collapse Control” list data
For Child Gallery in “Items” property add code – ThisItem
Step-5
Add labels according to the list’s columns and add show data
Step-6
Add code on all label’s “visible” property which are added in “Child Gallery”. Also, to have the Child Gallery show when button is clicked, we have to add code in Child Gallery’s on “Visible” property
“Visible” property – Switch(varShowId,0,false,ThisItem.ID,true)
Step-7
Add down arrow icon and up arrow icon.
Then first write code for the down arrow icon(Down arrow icon) on its “OnSelect” property –
If(varShowId=ThisItem.ID,Set(varShowId,0),Set(varShowId,ThisItem.ID))
And add code on visible property – If(Up arrow icon.Visible=true,false,true)
Step-8
On the down arrow icon and write code on it’s “OnSelect” property –
If(varShowId=ThisItem.ID,Set(varShowId,0),Set(varShowId,ThisItem.ID))
And write code on its “Visible” property –
Switch(varShowId,0,false,ThisItem.ID,true)
Please post your question, if you will find while implementing this process. Thank you.

Great tutorial
How would you handle Multiple Records for each employee
Example
Employee 1
Subrecord 1
Subrecord 2
Where in the data table you show “Expand-Collapse Control” list you would have two records for Employee 1 but different items under that employee
I would want to see both items when i expand the employee
Where to declare VarShowID? you didn’t mention in the tutorial. Its a half video.
