Have plus/minus icon option for collapsible menu.

[HristovCodes]

The title says it all, since they are both very similar in functionality I was very suprised to not find a menu variant with + and - instead of the up and down arows.

Specifically talking about this: https://daisyui.com/components/menu/#collapsible-submenu
And the collapsible alternative: https://daisyui.com/components/collapse/#with-arrow-plusminus-icon

Is this something that is planned or not? I could also work on this if contributions are open and if possible I'd love you to point me in the right direction before I start.
