i think you missed the point, its not stealing the idea, you are writing it to your rays, not taking it directly from his. lol

its like cars, you can not paint one car one colour and expect all other car makers not to use that colour,

you asked for ideas, i gave an example, how you write it is your own code, not rays.

you are saying no-one can use a drop down but the 1st ever person that used a drop down lol thats silly.

you write it in your own style,. thats not stealing copyright, thats see more your own code.
