LF: CSS with collapsible caves

What it says on the tin! Literally the only thing I want is the ability to collapse my caves for faster navigation, preferably with the ability to set some as collapsed by default. It gets really unwieldy scrolling through den with average to large packs. I want it to look like wolvden standard in every way except for the collapsible caves. Anyone know of somewhere I can find this?

Oooo, this would be so cool! subbing to this thread to see if anyone helps 

Do you want it to work on click, or on hover? On click would require javascript and I'm not sure if that's supported. On hover should be possible and I should be able to do it.

How would the hover part work on mobile, do you think? 

I'll test it and see! 

Check out the code on my den and let me know what you think. It works for me on mobile but some browsers behave differently. Optionally, I could make it just display the caves by default on mobile... unless that defeats the purpose for you. 

It works pretty well on mobile! On your profile the openable sections are too close together so it's hard to scroll without opening any as there's nowhere to put your fingers lol. But in the den it seems to work well! Is it possible to get this kind of CSS implemented while preserving the look of vanilla WD den pages? Thank you for your help!

Yes, it is 

It does work on my computer at least as well, though it is a bit glitchy
