I want to implement View more comments functionality like Facebook in Powerapp mobile application with SharePoint as the datasource.

My comments are available in SharePoint lists based on Post ID. I am using a global variable to show my comments in my Powerapp screen using below formula.

App.OnStart

Set(
glbCurrentRecord,
First(
Filter(
MyComments,
ID in Param("myID")
)
)
)

TextInput Control Text property which shows only one comment.

glbcurrentrecord.comments

I have multiple comments for my posts. Any idea on how to achieve something similar as below screenshot in Powerapp ?

Hi @Iantaylor2050 ,

Use collection to store filtered records from comments list based on ID and display the same in gallery items. Add more records

ClearCollect(glbCurrentRecord, Filter(MyComments, ID = Param("myID")))

Hi @Iantaylor2050 ,

You can create a collection OnStart of App as @Ashwin7104 said. But to implement the "See more" functionality, I would suggest you add an additional Gallery just below the comment text input control and a Label with Text set to "See more" and adjust the appearance of the text through the Label's font related properties. And, set a variable OnSelect to show/hide the Gallery mentioned above.

UpdateContext({ShowGallery:!ShowGallery})

For the Gallery, the Items property set to the collection, Visible set to the variable ShowGallery. So click on the Label will switch the visibility of the Gallery, just like the "See more" "See less" functionality.

Besides, if you have other controls below the "comments area", you can add a Container first then add the Gallery in it, cut and paste all the controls below into the Container as well so that they will change position adjust to the Gallery's hide and show.

Hope this helps.

Best regards,
