Over Ride select field
I'm a Sencha noob. I am trying to implement this over ride class so that I can either have blank or placeholder text in my selectField. I've added a JS Resource would this be the best way to do it? I can't seem to get it to work. Either I get a blank white screen or it doesn't work at all. Do I need to implement a store for this to work? My biggest question is with everything correct in my program will creating a js file with my override and including it as a JS Resource work correctly?
If you've created the select as a top level class you can just click "Create Override" and it will handle loading it for you etc.
If you didn't initially create it as a top level class, you can right click on it and select "Promote to Class" to make it a top level class.
Just a friendly advise:
