Collapsible Categories/Sub-Category vertical nav menu (left sidebar)

Continuing the discussion from Sidebar with categories:

@jord8on

I have a couple questions…

1. Would it be possible to add some highlight/indicator to show which category a person is in, by highlighting (or some other visible distinction) the category one is currently viewing?
2. Would it be possible to show sub-categories? Perhaps when a user is viewing a Category that has sub-categories, it would be great to see that Category open and showing the sub-categories beneath it.
   ↳ another point to this that would be nice is that if a Category has sub-categories, if there was a way to instantly see this… maybe kinda like the Discourse “Hide Details” feature works…

Example…

Category 1

Sub-Category 1

Sub-Category 2

Category 2

Category 3

Category 4

I posted that question ︎ in the Sidebar with categories - #30 by Stranik Plugin discussion.

I’m wondering how difficult it would be to customize that or write some custom code/plugin/theme component to allow extend that functionality and offer a nested folder type view of the categories and sub-categories.

Specs:

I want the Categories listed in the Sidebar menu to show the main categories and Categories with Sub-Categories would clearly indicate this. then when you click on one, it shows the sub-categories. And the last key functionality is that no matter where you are in the forums, the sidebar would indicate the source/location of the active discussion that you are viewing.

e.g. So if someone visits our forums from an organic google search, and end up viewing a Topic in a Sub-category, we want them to see that they are in a Sub-category, within the main Category.

Not sure how difficult it would be to develop this and/or what the cost would be, but if anyone can help with this, please let me know!
