Resolved A dropdown that can go to its sides

I want to have a dropdown that lists its items to the left of it. I already have an dropdown that goes from top to bottom like so



But I want another dropdown at the bottom of the screen that opens to the right. I looked around but couldn't find anything. I dont need to use dropdown menu if it cant do that but how can I make it otherwise ?

Here is how I want it to look I hope it gets my idea trough

 

I found a way to get what I want but i dont know if its a good solution in the long run




As you might have guessed I just copied and turned my other dropdown -90 degrees in the z axis



But as I said I dont know if it will have problems in the future any other ideas are welcome!
