React conditional divs with hooks - reactjs

Question

I am creating a signup form that will render differently depending on whether the person signing up chooses Post a project or Work on a project from the very first div in the form.
How can I render each div that follows in the form-group conditionally based on what is selected in the first div? I am using hooks and I have found that most examples are for the extends Component approach.
My form:
const signUpForm = () => (
<form onSubmit={clickSubmit}>
<div className="form-group">
<select onChange={handleChange("role")} class="form-control">
<option selected>I want to...</option>
<option>Post a project</option>
<option>Work on a project</option>
</select>
</div>
<div className="form-group">
<input
onChange={handleChange("name")}
type="text"
placeholder="Name"
className="form-control"
value={name}
/>
</div>
<div className="form-group">
<input
onChange={handleChange("email")}
type="email"
placeholder="Email"
className="form-control"
value={email}
/>
</div>
<div className="form-group">
<input
onChange={handleChange("password")}
type="password"
placeholder="Password"
className="form-control"
value={password}
/>
</div>
<div className="form-group">
<input
onChange={handleChange("studying")}
type="text"
placeholder="I'm studying..."
className="form-control"
value={studying}
/>
</div>
<div>
<div>{createInputs()}</div>
<button
className="btn btn-outline-primary btn-sm mb-3"
onClick={addSkill}
type="text"
>
Add more skills
</button>
</div>
<button onClick={clickSubmit} className="btn btn-primary" type="submit">
Sign Up
</button>
</form>
);
State:
const Signup = () => {
const [values, setValues] = useState({
name: "",
email: "",
password: "",
studying: "",
skills: [""],
error: "",
success: "",
role: ""
});
const { name, email, password, studying, skills, success, error, role } = values;
handleChange():
const handleChange = name => event => {
setValues({ ...values, error: false, [name]: event.target.value });
};

You should first divide the signUp in two parts and then call second function based on value of "role" from state.
The idea is to return the divs from second function based on state of first input.
const signUpForm = () => (
<form onSubmit={clickSubmit}>
<div className="form-group">
<select onChange={handleChange("role")} class="form-control">
<option selected>I want to...</option>
<option>Post a project</option>
<option>Work on a project</option>
</select>
</div>
{this.renderInput()}
<button onClick={clickSubmit} className="btn btn-primary" type="submit">
Sign Up
</button>
</form>
);
renderInput() {
if (values.role === "post") {
return (
<div className="form-group">
<input onChange={handleChange("name")} type="text" placeholder="Name" className="form-control" value={name} />
</div>
<div className="form-group">
<input onChange={handleChange("email")} type="email" placeholder="Email" className="form-control" value={email} />
</div>
<div className="form-group">
<input onChange={handleChange("password")} type="password" placeholder="Password" className="form-control" value={password} />
</div>
<div className="form-group">
<input onChange={handleChange("studying")} type="text" placeholder="I'm studying..." className="form-control" value={studying} />
</div>
<div>
<div>{createInputs()}</div>
<button className="btn btn-outline-primary btn-sm mb-3" onClick={addSkill} type="text">
Add more skills
</button>
</div>
);
}
}

You want to test the role state value is truthy/falsey and render the rest of your form on that value.
const SignUpForm = () => (
<form onSubmit={clickSubmit}>
<div className="form-group">
<select
defaultValue='unselected' // set default value here
onChange={handleChange("role")}
className="form-control" // fix className here, class alone isn't correct in react
>
<option value='unselected'>I want to...</option>
<option value='post'>Post a project</option>
<option value='work'>Work on a project</option>
</select>
</div>
{!!role && (
<Fragment>
<div className="form-group">
<input
onChange={handleChange("name")}
type="text"
placeholder="Name"
className="form-control"
value={name}
/>
</div>
<div className="form-group">
<input
onChange={handleChange("email")}
type="email"
placeholder="Email"
className="form-control"
value={email}
/>
</div>
<div className="form-group">
<input
onChange={handleChange("password")}
type="password"
placeholder="Password"
className="form-control"
value={password}
/>
</div>
<div className="form-group">
<input
onChange={handleChange("studying")}
type="text"
placeholder="I'm studying..."
className="form-control"
value={studying}
/>
</div>
<div>
<div>{createInputs()}</div>
<button
className="btn btn-outline-primary btn-sm mb-3"
onClick={addSkill}
type="text"
>
Add more skills
</button>
</div>
</Fragment>
)}
<button onClick={clickSubmit} className="btn btn-primary" type="submit">
Sign Up
</button>
</form>
);
