This simple theme component allows for hiding lock badge icons for secure categories in the drop-down category selectors, header breadcrumbs, navigation sidebar menu, search results, and corresponding category chat channels.
Some people find the lock icon a bit misleading, thinking it means the category is locked and inaccessible. In Discourse, one can only see what they have access to, so the lock icon is simply an indicator that the category is restricted to others. Moreover, a lock icon is also used to signify a closed topic (this component does not hide those). Thus, some admins may simply wish to hide the category lock icon entirely, and that is what this component does.
Settings
There is one setting - an option for toggling for Staff, since seeing the lock icon can be a useful indicator for Staff members.
Nice! I’ve hacked a solution together for this a few times on various sites - brilliant to have it as a configurable theme component. You’ve got a knack for churning out some really useful customisations!!
Just checking - is it possible to use a Category selector instead of specifying each slug and ID? I would have thought that would be more durable for those like me who occasionally rename / move categories. Also, it might help with managing subcategories.
The lock icons are actually a bit tricky to hide in some places, that’s why the category ID is also required. I’m trying to figure out doing it also for search results but singling out select categories in the results seems near impossible.
oh good point. Can separate the slugs with a forward slash like category-slug/subcategory-slug (ie: boats/motorboats;8) and just use the subcategory ID. But a subcategory will inherit the parent category if you are hiding the lock icon there.
I will add this to the OP.
Yea I actually started developing it this way but I was getting results that were not what I expected. I will continue to work this method out because it is preferred for the reasons you describe. Thanks for the great feedback Nathan, I appreciate it.
I have updated the component for some of the field descriptions with corrections and more information about subcategories, and also edited the OP with the correct instructions for using subcategories.
Excellent theme component that was created in response to a question I had on another topic here. Can’t thank you enough for putting in the time to help us non-CSS experts manage their forum more effectively.
Ooh, thanks for this. I find all of those icons to be more distracting than informative — especially because they can mean so many different things in terms of actual access.
Nice!!! I love the extension to the navigation sidebar and search.
Have you had any further thoughts on having it as a category selector? To my ignorant mind, both the slug and the ID should be relatively straightforward to obtain from the category object.
heh, yea I worked on this a bit and got close but I was having trouble with the javascript to get the category slug from the ID. I know it’s possible and which methods in the existing library to use and the basic framework, I just need to spend some more time on it and debug. I have it so I can get most of it with the category selector, but in some places it requires the slug. I’m sure someone more proficient in javascript would be able to do it faster. LolaBot (GPT) was no help at all and kept creating nebulous arrays from thin air. lol
When I have some downtime, finishing it is on my Todo list. Also, now I have some more javascript gurus at my disposal. hehe
This is possible and I toyed with it when I was doing the component. When I replaced it with the unlocked padlock the difference in appearance wasn’t that noticeable because the icons are so small (the locked and unlocked ones don’t look much different at that size). I may revisit this. Even the key didn’t look great at that size. TBH.
It didn’t work on the sidebar last time I looked - that was probably fixed ages ago! But it works well now - thanks!
Perhaps the best path of all would be to combine the two TCs into one, as they both pertain to icons associated with categories, and this is an area of overlap.
I’m open to whatever works. I don’t have time at the moment to work on this, but I know we have a general plan to make the hide lock badge component official, we just haven’t gotten to it just yet. I’m also wanting to improve it a bit - the category setting in particular isn’t intuitive enough; I really dislike those kind of delimited text input fields with separators. Probably could use a bit of a code refresh and update given some of our core changes. Feel free to fork and hack! PRs always welcome. I think this was one of the first theme components I built.
When I apply this to a Category, it also affects all subcategories of that Category (unhelpfully); this prevents it from being useful in my context of having restricted private subcategories.
makes quite a bit more sense for categories and subcategories in Discourse. 
seems a much better fit for closed topics.
