Good day,

I have a gallery with a nested gallery. The gallery is sorted and grouped by conference names, and the nested gallery shows title and subtitle. I am trying to get only records to show who's subtilte is "Registration" from a drop down list in the Sharepoint List data source.

I have not been able to figure out how to filter the nested gallery though so it removes everything other then those with a "registration". Is there a way to do this.

GroupBy(Filter(SortByColumns('Expenses for Approval',"Title",SortOrder.Ascending),StartsWith(Title,ConfSearch_1.Text)),"Title","GroupbyConf")

Hi @rowhites ,

Can you please share the Items property of the nested gallery and the name of the column you wish to filter?

Sure things, the nested gallery items: ThisItem.GroupbyConf

The column name in the SharePoint list is Items

I deeply appreciate any help. Looked all through the web and other sources with little help.

Hi @rowhites ,

Try this for the Items property of the nested gallery:

Filter(ThisItem.GroupbyConf, Item.Value = "Registration")

HI @rowhites ,

Indeed, since Item is a choice type column, you need to filter for the value.
