1. accepting of other thoughts and ideas
open to suggestions/discussion/ideas
To be 'open to' something means to be willing to discuss something or to consider it. "I am open to your thoughts on this if you'd like to share them with me." If you are liable to something or somehow vulnerable you can also say you are 'open to' something. "She has left herself wide open to criticism coming out with a comment like that." "Anyone not holding a ticket is leaving themselves open to being fined." You can also use 'open to' if you want to say something is available or accessible. "The collection is open to the public from May until early June."
I'm really not sure what to do about this problem, but I am open to discussion on the matter.
