in Using jQuery • 7 years ago

Hi ,

below code is working fine, but while filter is applied if you use move left and right ,i am facing problem,

please can any body help us in this case.

1) Individual Filter is working fine.

2) Move right and left is also working fine

3) if filtered options are moving to right to left or vice versa , then remove the filter text then , see moved options are back to the list . orginal list is appearing.
