How to expose blueprint value to be edited in the Level in the Details tab?

Hi all i am using Data table for my game and i wont to expose my row names to be edited by the level Designer.
what a did is promoted the variable to be public and clicked the eye so i can see it in the level see on the Image.

but dos not give me list. like inside the blueprints.

i some one can show me how or point me to some guide it will be nice.
Have nice day.

What you did there is creating a variable of your current RowName. That is just going to be Stone(the current option or what you write in it). You could either use GetRowNames for your data table (creates an array) or you could use a variable of type DataTableRowHandle.

Makes sense. Thank you
