[chiester]

Added the ability to pass a maxLength attribute so the length of the input in SimpleSelect can be limited.

Any chance this'll get merged @furqanZafar? It's a useful attr and the PR is pretty straightforward.

Why make a default limit? this is not backward compatible (i.e. Some usages may need more than 255 characters).

[chiester]

Can't you just override the default? maxLength=1024 , or whatever

[elisherer]

You didn't understand me. If I were to use this library and happen to have values with more than 255 characters, upgrading to the version with your feature would break my code unless I specify the maxLength prop. It usually a better practice to make new features "opt-in", meaning not enforcing it unless wanted, and upgrading should not force you to make changes in your code.

[chiester]

Thanks for the clarification. That's a good point.

With the PR I did (#160) it will be solved by passing inputProps.maxLength.
