Customize elements in react-native-dropdown-picker

Question

React Native Dropdown Picker is the most popular library to implement a dropdown in React Native. But in the library, I could not find a way to customize the dropdown arrow and the ticks in the dropdown list. They are by default in black color and cannot be customized with my knowledge.

Basic implementation:

import DropDownPicker from 'react-native-dropdown-picker';

function App() {
  const [open, setOpen] = useState(false);
  const [value, setValue] = useState(null);
  const [items, setItems] = useState([
     { label: 'ice-cream', value: '1' },
     { label: 'strawberry', value: '2' },
     { label: 'grapes', value: '3' },
     { label: 'fruit salad', value: '4' },
     { label: 'jello', value: '5' },
     { label: 'apple', value: '6' },
  ]);

  return (
    <DropDownPicker
      open={open}
      value={value}
      items={items}
      setOpen={setOpen}
      setValue={setValue}
      setItems={setItems}
    />
  );
}

There is a prop in the called arrowIconStyle. But for that also, I could not find a way to give a color as a style.

Ex: arrowIconStyle={{color: 'white'}}

Unfortunately this does not work and gives an error: 

Type '{ color: string; }' is not assignable to type 'StyleProp'.ts(2322)

Can someone please help me regarding this?

Thank you.

Answer 1

try to change the arrow icon and implement your own styles for the icon like the following: https://snack.expo.dev/@hewr/57a779

Answer 2

//to change the dropdown box style
dropDownContainerStyle={{
  backgroundColor: "#dfdfdf"
}}

// to style the selected item style
selectedItemContainerStyle={{
   backgroundColor: "grey"
}}

You can customize the icons in this way.

import DropDownPicker from 'react-native-dropdown-picker';
import AntDesign from 'react-native-vector-icons/AntDesign';

                    <DropDownPicker
                    showArrowIcon={true}
                    ArrowDownIconComponent={({style}) => (
                      <AntDesign
                        style={{marginRight: 5}}
                        color="green"
                        name="check"
                        size={20}
                      />
                    )}
                    ArrowUpIconComponent={({style}) => (
                      <AntDesign
                        style={{marginRight: 5}}
                        color="red"
                        name="check"
                        size={20}
                      />
                    )}
                    showTickIcon={true}
                    TickIconComponent={({style}) => (
                      <AntDesign
                        style={{marginRight: 5}}
                        color="green"
                        name="check"
                        size={20}
                      />
                    )}
/>
