I have a list in my SharePoint and now I'm trying to do kind of searching in PowerApps by using 3 components:
Dropdown (I want it to contain all the Columns names From the Data Source which is Sharepoint List)
SearchBox (Type the text I want to find)
Gallery (showing the results)
What I want to do is choosing a specific Column from the dropdown, then using the SearchBox to search on that particular Column I selected from the Dropdown to give me the results on the Gallery showing that selected column in the dropdown.
