I have a text field/column "Building" in a Power App. I want to modify this to a drop down where choices are selected from another SP List. I also want the user to be able to search for a value like a Combo Box. What is the syntax needed?

Are you using a Form to manipulate the Building data or creating the interface from scratch?
I’d say if you want a ComboBox experience, better use a ComboBox than a drop-down. 🙂
easiest would be to add a form, connect it to your SharePoint list and add a ComboBox to the field. Having done that you can add the SecondList.Column to the Items of your combobox.
