[CLOSED] ListFilter problem
Hi,
I'm implementing a local ListFilter functionality. Please refer to the code below. When I uncheck all the individual Industry checkboxes on the list, the parent Industry filter becomes unchecked, too, as expected. However, it doesn't work the other way around: if I uncheck the parent filter, its individual options selected, if any, remain checked off. Please suggest a workaround.
Thanks,
Vadym
