Firstly, I agree with @maheshkasindi - I’d recommend not using texts here - option sets are much better suited for this, and give you way more possibilities and functionality, whilst at the same time making everything much simpler.
Having said that, if you do want to use texts, it should be as simple as setting the dropdown’s type of choices to text, and the source to the User’s list of Types of hair.
Is that what you’ve done already?
If it is, then presumably your Type of Hair field on the User is not set as a list (although you said in your post that it is, so I’m guessing you haven’t set the dropdown data source correctly).
But, I’d definitely suggest switching to use an option set for this instead.
Yeah I think I am gonna do this, it’s way more simple.
It was for a more simple management system, in the future I prefer to manage this in the database than into the design system for a better visibility.
It’s actually for video games. I use the user and hair for more simplicity.
But you choose a game, then you choose a map based on the game.
So if a map is added, I can add it in my app simply.
