@Floriferous What about the optional prop? Do you have an illustration of the problem?

[Floriferous]

We could extend the check to include both children && optional.

Here's what it looks like, all the empty space below the StepIconComponent is the empty labelContainer.

If I change the labelContainer to display: 'none':

EDIT: Forgot to specify we're using the alternativeLabel: true prop

[oliviertassinari]

@Floriferous Thanks, sounds great. It seems that we could also take care of the paddingRight style if no labels are shown.

[Floriferous]

Cool :)

Just curious about code style, why do you prefer the ternary cond ? <Component /> : null over cond && <Component />?

[oliviertassinari]

Because (0 && {}) === 0. It requires to have the guarentee that cond is a boolean.
