title: Disable the collapse action from a Material-UI Stepper component
body: <p>I am building a react site using <strong>Material-UI</strong>, specifically, the <strong>Stepper</strong> component.</p>
  
  <p>Is there any way to disable the collapse and expand of each <code>StepContent</code> for vertically oriented <code>Stepper</code>? I want to keep the styles of the component, but I essentually want all content of the stepper to be visible.</p>
  
  <p>An example of a "collapsing" <code>Stepper</code> is <a href="https://codesandbox.io/s/ry36xp2pzn" rel="nofollow noreferrer">here</a>. I simple need to figure out how to disable the collapsing.</p>
  
  <p>I've read the <a href="https://material-ui.com/demos/steppers/" rel="nofollow noreferrer">docs</a> back to back and haven't found an obvious way to do this, yet it seems like it should be doable.</p>
