I have simple from which i used semantic-ui-react to create it :
  <Form onSubmit={this.handleSubmit.bind(this)}>
          <Form.Field>
            <Input placeholder="From ..." type="text" ref="from" />
            <Label pointing>please enter valid email adress</Label>
          </Form.Field>
          <Divider />
now i cant access to value's of the input. here is my code:
  from: this.refs.from.value
it's all undefined.how can fix this ?
 
                        
I recommend to use
Formand related components in the controlled way, because most of SUIR components are functional, so they don't support refs. I've a codepen to show it in action. There is also example in docs.
