SelectMenu Multiple Improvements: Deselect All, Badge instead of comma

[fabianwohlfart]

Description

I was looking through the v3 alpha5 and found that select menu with multiple will have a width of 0 if you deselect all.

Also instead of comma separating the selected items it would look great to have badges with an x on the right side, so it's easier to differentiate. compare to this (taken from kirby cms)

Hi @fabianwohlfart 👋

This happens because there is no placeholder defined on that demo, however, if you define a placeholder, then you are fine 🙏
