Styling issue when the grouped checkboxes are invalid

[TheSharpieOne]

There is a styling issue when the checkbox groups are invalid.

Also, can you alias minChecked and maxChecked to be min and max as props on the AvCheckboxGroup (or just modify the existing min/max validations to work with arrays) to allow for something like:

<AvCheckboxGroup name="checkboxExample" label="U Pick 2!" max="2" min="2" required>
  <AvCheckbox label="Bulbasaur" value="Bulbasaur" />
  <AvCheckbox label="Squirtle" value="Squirtle" />
  <AvCheckbox label="Charmander" value="Charmander" />
  <AvCheckbox label="Pikachu" value="Pikachu" disabled />
</AvCheckboxGroup>

@TheSharpieOne good catch!

[reeseschultz]

I will update the aliasing. Also, I'll change the styling.

@TheSharpieOne I pushed a couple commits to address the issues you mentioned. When you have time, please take another look and let me know what you think.

The min and max checked validation also have the style issue. Not sure the best way to handle this as this is where it really starts to get different from radios.
The styles themselves are tied to the DOM's ValidityState. You could use .setCustomValidity on the underlying checkbox to control the ValidityState.

[reeseschultz]

Thanks for your feedback. I'll dig into the code and come up with an appropriate fix.

[reeseschultz]

@TheSharpieOne The .setCustomValidity function did the trick! Much appreciated.

Also, thanks for bearing with me. I just learned React for the sake of updating this library. Is there anything else you want me to add/change before the merge?
