@carsonip thank you. We have decided to add this feature though the implementation might be a bit different. Ill review this soon and give you feedback.

The CLA signature is fine now.

@carsonip sorry about the delay in this finally ready to add this feature. Im wondering if it might be better / more flexible to add an option ignore that you can set to any valid selector? thoughts?

[apsdehal]

I agree with @arschmitz that an option would be more convenient in this case.

[carsonip]

@arschmitz Sorry for the late reply. I would love to improve the request. Could you elaborate more about the ignore option? Which element should it belong to?

[apsdehal]

@carsonip ignore option will have a value of string which would a valid html selector for the items which should not be filtered.

[carsonip]

Sorry for the wait. I have updated the PR according to the comments. Not sure if there will be a significant performance hit since we will create a jQuery object from each item such that we can use the is() function. There will certainly be no performance hit if data-ignore is not set.
