Change Title Background Color when expanded

[duczz]

when you use multiple expander cards its hard to see which one is currently expanded, it would be great when the activ expanded expander card header has a other color.

so is it possible to add a function thats allow to change the title background color from the expanded card? (only when expanded)

@duczz open

        type: custom:expander-card
        title: "Räume"
        expander-card-background-expanded: "#ffffff12 radial-gradient(circle, transparent 1%, #ffffff12 1%)"```

Perfect, looks good 👍🏻👍🏻 Is it possible to Change the color only from the top Line (Räume ) too? Currentlly it looks like it change the General backgroundcolor without the entities

[MelleD]

Yes only the complete background. The other option for the button looked weired when you have padding. But if you see the PR you could also easily add a option for button background expanded.

IMHO this make more sense because you can the group which is related to the expander make also sense when you have more than one

Alright thank you 👍🏻

What I would like to try is to make the state open/closed into a var. Maybe then you can do everything what you want with card mod if you have the state —var(open)

But I have no experience to expose variables to card mod and have to test it when I have some time ;)

That would be cool, that makes it much more flexible 👍🏻
