Howdy, @fbrugger…thanks for writing in, and sorry for some of the confusion on this thread. You can specify how particles should show up for “current” and “ancestor” links in your Navigation using native options in the Builders. To do this, go to your Navigation Element → Menu → Active Links Setup:
This is where you can tell your Navigation Element to place certain graphics or particles in their “active” state for certain menu items. By default, you can see that this is turned on for “Current Link” and “Ancestor Links” at the top, so this means that any of the last three toggles you enable will be applied to both of those situations. So, if you wanted your Primary Particle to be always visible for both of these contexts, simply turn that switch to On and you should get your desired result. If you only wanted to target the “Current Link,” you could turn Off the “Ancestor Links” control, or vice versa if you only wanted to highlight the tree leading to the current link.
Hopefully this helps to clear things up, cheers!
