Show/Hide Select All Tree Checkboxes
We are using a 3-level nav tree (Sport-Country-Competition) with nodes being selected only on the third level.
Upon running usability tests, we identified that the absence of a "select all" option is a pain point for our users. Should the users want to select all the competitions from a Sport-Country, they have to select each node one-by-one, which results in an unnecessary interaction cost.
We are considering replacing the country flag icon with a checkbox, should the user mouse over the country node; this way the user will check the country checkbox for all competitions to be selected.
My questions below:
- Revealing/Hiding the Select All checkbox will promote recall over recognition; will the impact be considerably bigger from the benefit?
- Should we expand the country node upon selecting it to show all children being selected instantly?
- Any other alternatives/suggestions we can think of?
