Inside modal - sticky element is disappeared - modal

[jo-san]

Hi Author,

I have found it really cool plugin for sticky elements. Thanks for that.

I have a requirement where i need to keep a sidebar sticky inside a modal. When i try to implement it with sticky-kit my target element seems disappeared.

$(".modal-alternate-filters").stick_in_parent({ parent: ".modal-alternate-wrapper", offset_top: 10, spacer: false });

Is there any work around to make this work inside modal / fixed element.

Thanks,
Josan
