Accordeon Hika only generates links for child item

do you have the option "target element" on "image only" and "use images" on "no" ?
this can not be
if you want to have the target on images only, then the images are forced to show, else you can not toggle (which is the wanted behavior of an accordion)

Thank you, I understand that is the intended behavior of the Accordeon, though not everyone cares about the ability to toggle. Clicking on the menu item (rather than "+") similarly opens the menu displaying the submenu items.

The only remaining issue we're trying to work through is that the menu now collapses again on its own when clicking on a submenu item. I've compared the module configuration to an old installation that works and can't figure out how to keep the menu expanded when traversing submenus.

by my side if I go there
spectrumsignsoc.com/develop/categories-l...category/388-banners

the menu is opened on the active tree of "custom signs", so this is correct, right ?

That is the old site that works.

The site we're trying to get working is
www.willowcreekgraphics.com/

To illustrate the issue, clicking on "Vinyl Graphics" in the menu will expand the menu and display the associated submenu items in the content area as well.
Clicking on the submenu item "Solid Color" will cause the child menu items to be displayed in the content area, but the menu then collapses.

ok I see
do you have the latest 2.0.21 version of the module ?
CEd

The version installed is 2.0.19, which appears to match the current version on your site's downloads:
