In my case I want to add Unique option into the “Combo Box String” and I need to check if Combo Box String"'s options number is equal to a options Array in my code.
But neither checking if option is Unique nor Getting “Combo Box String” options number I can not find the function in the blueprint.
I have written up a feature request ( UE-22130) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
You could create a combo box with zero elements in it and then add and remove the options dynamically. Every time you add or remove an option you and 1 or subtract 1 from an integer. I hope that this information helps.
Make it a great day
also you can use find option index in blueprint
