Hello Arnav, can you help me in this situation:

// start without being checked
Type: ( ) entry ( ) exit

If you check entry, show the select "country"

Type: (*) entry ( ) exit

// show country selection
<div>
<label>Country</label>
<select id="country" required>
<option value="">Choose...</option>
<option>United States</option>
<option>Italy</option>
<option>Portugal</option>
</select>
</div>

// If you check the output, show the "country" selection and the "quantity" radio
Type: ( ) entry (*) exit

// show country selection
<div>
<label>Country</label>
<select id="country" required>
<option value="">Choose...</option>
<option>United States</option>
<option>Italy</option>
<option>Portugal</option>
</select>
</div>

// show the quantity radio
Quantity: ( ) low ( ) high

Note: When starting up, the radios should show without being checked
