Replication the field using a button

[fithaN]

Hi,
I am creating subjects form a dropdown menu which gets replicated after I press a button.
Is there a way I can implement it as below using the material drop down?
Below is what it should look like.

I don't really understand what you're asking but if you're looking to make a dropdown that appears on a button click perhaps this example will help

            <DropdownToggleButton onPress={this.dropdown.focus} />
            <Dropdown
              containerStyle={{height: 0, width: 0}}
              pickerStyle={{width: 200}}
              dropdownOffset={{ top: 32, left: -190 }}
              ref={e => this.dropdown = e}
              data={data}
              renderAccessory={() => null}
            />
