Setting Dropdown input field Default Value to Logged User Name

[pperrot1]

Hello,
I have a couple of dropdown inputs that serve as inputs to a gallery based on a Sharepoint list (Projects List). Once selected, the ˜project details˜ Edit Form opens for editing on a side gallery.

The project list has a ˜Responsible Person˜ column filled with a user assigned to each project.

One of my filtering dropdowns is based on that ˜Responsible Person˜ column. The Items formula to the dropdown is: Sort(Distinct(Projects List,'Responsible Person'.DisplayName),Result,Ascending)

I want that dropdown input to default to the logged User's name on start (so that the user can go straight to his assigned projects), but I also want them to be able to select other team members' names and be able to edit their projects in case they are on vacation, etc. How do I set that default value? Also.. .DisplayName doesn't seem to be a function that the Dropdown input understands.
Please help!

In the dropdown box's Default property, you can use this formula, assuming the display name in your source is their O365 username.

Office365Users.MyProfileV2().mailNickname

Yes, it worked!
I just had to tweak the formula to:

Office365Users.MyProfileV2().displayName

Thank you very much!!!
