Multi step Form and support for searchable multi select dropdown

[lateshK]

Hi,

1. There is support for multi step form, like sign up forms where on each form user enters info and click next to display step
2. Support of searchable multi select drop down like (react-select)

The multiform is not necessarily supported out-of-the-box, but you could add an onUpdate callback to the form itself, and then update local state to keep track of whether the necessary data was set in the form to allow the "next" button.

It'd be interesting to think about adding a button type to the available FormItems so you could write conditions around it.

<Form
  instance={instance}
  onUpdate={(id, value) => {
     // Update local state to detect whether the 
     // form has been updated with the necessary data
     // to render the "Next" button
  }}
  onSubmit={(hasError) => {}}
/>

{doShowNextButton && <button>Next</button>}

And I think the searchable dropdown would be pretty interesting. I created #16 as an enhancement for this.
