fix: Selectively show custom checkbox component

[Yimura]

Description

This PR changes the behaviour of the underlying checkbox component to not render unless the item is selected.

Fixes #123

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

People previously having relied on their custom checkbox always rendering will be impacted. As the checkbox is unable to know if it's selected or not I wouldn't expect anyone to be negatively impacted by this.
