Hello.
I have an Excel table called "Tabela_ACTIVITIES".
In this table I have 3 columns: "DEPARTMENT", "TIMELINE", "ACTIVITIES".
On PowerApps, I have 3 dropdowns: one for "DEPARTMENT", another one for "TIMELINE" and a third one for "ACTIVITIES".

What I would like to do is this.
When I select "DEPARTMENT" and "TIMELINE", the "ACTIVITIES" dropdown should just show the activities regarding my previous choice.
Thank you.
