We have an option for users to search the tree, so we may only see some of the results, specifically the subcategories
The question is: How should the partial category checkbox (Apparel in this example) behave? There are 3 options:
1 - be disabled
2.1 - When users click the partial in becomes fully checked (normal checkbox behavior) - and the 4 leaves will be shown (this ignoring the search filter)
2.2 - When users click the partial in becomes fully checked and only the 1 leaf (Recreational $ Sporting) will be shown complying with filter, but hiding some of the checked items
3 - Only allow users to uncheck the Apparel checkbox - un-expected checkbox behavior but making sure filter shows the effect of the user action.
