Add item to List/Collection?

[BrianHFASPS]

I have one dropdown that I use to filter a list in a second dropdown. This is my code:

Distinct(Filter('[dbo].[StuListSmall]',Grade='Covid Grade Dropdown_1'.SelectedText.Value),Section)

I want to add an option to top of list that is 'All'. I am sure there is some easy way to do this but I can't figure it out. I would prefer not to have to make a collection since with this it is cleaner and more dynamic. Thanks.

So my fix was in first dropdown in OnChange I put this in:

ClearCollect(SectionList, {Result:"All"});Collect(SectionList,Distinct(Filter('[dbo].[StuListSmall]',Grade='Covid Grade Dropdown_1'.SelectedText.Value),Section))

Then my second dropdown just references the SectionList collection.  I guess that is the way to do it?
