Want to Expand/Collapse Devices Reaction Solved

I suck at making reactions.

Need help with making an advance reaction to toggle between states both expand & collapse using one button in my touchosc controller I’m currently building?

Seems simple, but spend three days now. I tried the Device is collapsed value but no luck and Im not able to figure out the more in depth reaction programming any help would be appreciated.

I’ve included my css script and template below.

Update!!!
With the help of amazing GlennV who is kind enough to help me out, we got the show/hide device or blue hand device selected working.
Which you can download and add to your own projects.

Note, There is a css bug and GlennV will raise the issue. But in the meantime it works, you will need to change and assign it to your own button and it should be working with momentary button config.

Thank you GlennV
