How to access dropdown objects childrens?
Hi! I'm currently working on project, where we want to navigate menus with controller. Problem now is that how I can access and select dropdown menus options? So in scene I have dropdown object with 4 options. Current task is to be able to navigate in those options only with controller.
This script is attached to the Canvas. Canvas has canvas reycaster,canvas scaler,canvas and rect transform components.
Problem lies on a line 106.
Any help is appreciated!
