In the usability study, participants were asked to use the list of participants (to send a message). When they found the word "Participants" in the navigation, they were confused because the Participants link is both a node with children and a link to a page. People were clicking on the right-arrow beside the Participants link, expecting to be taken to the Participants page, but it just expanded the nodes below.
Two actions should be taken.
- To avoid confusion, a rule needs to be enforced that prevents nodes with children from being links to pages.
- Icons for expansion of sub-menus should be reviewed, perhaps using + and - icons instead of triangles, so the purpose of these icons becomes clearer.
The particular case (with users accessing a list of participants) may be resolved if the participants list is merged with the users list, but the general issue should still be dealt with.
This was a blocker for 2/6 participants.
