How to change font size and colour for search input text?

Thanks for this great library, it helped me a lot when I am trying to implement a screen.
But it could be more convenient if we can add more customizable props. At this moment I want to style the search box inside the Dropdown ( placeholder & input style, custom search & close icon... ).
Hope to hear from you soon.

Because the source is distributed with TS, type checking in CI will check every usage of the library and unfortunately cannot be ignored with normal tsconfigs

An example on how to distribute to commonJS https://github.com/callstack/react-native-builder-bob

Hi, Is it possible to change the design or layout of the label or result portion?

I already done i with list items. I want to style the result with the same design with the item list.

Is It possible?

I found renderLeftIcon but I can't put selected image uri for it.

renderLeftIcon={() => (
                <>
                    <Text>Image left</Text>
                </>
)}

Here's my sample data array

const data = [
    {
        value: '1',
        label: 'Samantha Calls',
        phone: '0932131',
        image: {
            uri: 'https://www.vigcenter.com/public/all/images/default-image.jpg',
        },
    },
    {
        value: '2',
        label: 'David Salon',
        phone: '0932131',
        image: {
            uri: 'https://www.vigcenter.com/public/all/images/default-image.jpg',
        },
    },
[

Hoping for your response. Thank you

Sometimes dropdown crashes with the below errors
Invariant Violation: [1297,"RCTView",1,{"height":"<<NaN>>"}] is not usable as a native method argument
Invariant Violation: [1295,"RCTView",1,{"height":"<<NaN>>","justifyContent":"flex-end"}] is not usable as a native method argument

IOS app is working fine but android is crashing.

How do I know state of dropdown box open vs closed in order to set right hand icon.

I could track via onblur and onfocus but there may be better and safer way

2: Can I do a custom renderItem callback ?

Hey @hoaphantn7604, first of all thanks for this great library.

There is just one issue I'm facing is, Dropdown data doesn't get updated when dropdown is open (and data is empty),
and when dropdown data gets updated (for e.g null to [...]) I have to close dropdown and open it to display data.

Require cycle: node_modules/react-native-element-dropdown/index.ts -> node_modules/react-native-element-dropdown/src/SelectCountry/index.tsx -> node_modules/react-native-element-dropdown/index.ts

node_modules/react-native-element-dropdown/src/SelectCountry/index.tsx
这个文件下的这句要注释掉,不然会导致循环引用

//import { Dropdown } from '../../index';

If the data array contains first item with a value of 0, selecting that first dropdown item would render the placeholder instead of the first item.

import React, {useState} from 'react'
import { StyleSheet, View, Text } from 'react-native'
import { Dropdown } from 'react-native-element-dropdown'


const DropdownMenu = props => {
    const [selectedTab, setSelectedTab] = useState(null)

    const tabs = [{label: 'first', value: 0}, {label: 'second', value: 1}, {label: 'third', value: 2}]

    const renderItem = (item) => {

        return(
            <View style={styles.item}>
                <Text style={styles.textItem}>
                    {item.label}
                </Text>
            </View>
        )
    }

    return (
        <Dropdown 
            style={styles.dropdown}
            placeholderStyle={styles.textItem}
            selectedTextStyle={styles.textItem}
            data={tabs}
            search={true}
            labelField='label' 
            valueField='value' 
            placeholder='Select Group'
            searchPlaceholder='Search...'
            value={selectedTab}
            onChange={ item => {
                setSelectedTab(item.value)
                props.selectedCallback(item.value) // callback for changing Tab page
            }} 
            renderItem={renderItem}
        />
    )
}

export default BleDropdown

const styles = StyleSheet.create({
    dropdown: {
        height: 25,
        width: 125,
        margin: 10,
        backgroundColor: 'white',
        borderRadius: 10,
        padding: 10,

Hi @hoaphantn7604, Is it possible to implement pull to refresh or refreshControl in the dropdown items? Thank you

Hi @hoaphantn7604,

How can I get the value from nested object?

Here's my data it has name under metadata object

Is it possible that I can get it and put it in labelField="metadata.name"?

Regards,
Paul

Any suggestions on how to place list of selected items in (on) the "select item" line where placeholder text is located (as with dropdown) instead of displaying them below?

How i can set min Height? because i have a list with 2 items and dropdown list is big

Hi Team,

       I have found a small UI design issue in your plugin. The issue is in Dropdown. Please replace the view tag with fragment tag for _renderListTop() and _renderListBottom() in src ---> Dropdown ---> index.tsx and remove flex:1 in container from styles.ts. After doing this, the dropdown height is auto set to its items height.

Screenshots for reference:-

Hi, I was trying to use valueField props for control dynamically my dropdown components. I have this Array<Tax> objects at below.

I used value and label field like below

Label field is working smoothly but valueField not. I suppose when I write valueField='value' Dropdown itself onChange method (_value)=> parameters should come with my <Tax> object key name which is value but when I tried this way I faced (_value)=> parameters came with entirely <Tax> object

Is there any problem on your code or am I doing something wrong ? Thank you :)

Code

:

when API provide data for initial value , how to implement initial value from API to component dropdown.
im already try using props value , but still nothing , initial value not render autofill at UI dropdown

It would be a privilege to have ability of customizing Label Field data and it wouldn't be only one filed to display
for example: I like to show the selected item like this,
"John Smith, 25, California"
{fullName, age, state}

Anyone having this issue? I can "fix" this by giving containerStyle={{marginTop: -60}}. I'm not sure why it happens.

I'm not able to make the height of the container list fit its content?

Hi I'm having this issues in Android. Please help!

would it be possible to add a prop for the function that filters the list (function onSearch in Dropdown component)?

I'm using version 1.2.6 with react-native 0.65.1

In code examples for Multi-Select it is implied that onChanges passes an array of objects (based on item.value).

In my case it appears that onChange is supply object key denoted by valueField.

onChange={item => {
   setValue(item.value);
}}

In typescript world (as example)

assuming data array is of type IndexedValue[]
where

interface IndexedValue {
  index: number,
  value: string
}

then in my case I see onChange returning a string list and not IndexedValue list.

Can you please confirm correct operation.

Here is search bar:

When you click on input, it opens dropdown with new input:

When you click on "Search", modal moves, but dropdown doesn't:

Here is the code:

Hi @hoaphantn7604,

Is it possible that I can add button below search input field?

Below is the sample web design and I want it in react-native also. I want to add "add new customer button".

Hoping for your response. Thank you

How to close or open dropdown from another event ?

Hi hoaphantn7604,

First of all - gread job with react-native-elemen-dropdown. I like the flexibility of the component and how it behaves.

I would like to ask you for small improvement. In my case I'm using the dropdown with custom search input in Modal with KeyboardAvoidingVIew. The problem is when the keyboard is opened, the KeyboardAvoidingView is changing the layout and the position of the dropdown is not updated.

Thanks in advance!

Best Regards,
Ivan

So I have three elements in my Dropdown, but it has way too much space.

OnonEndReached and onEndReachedThreshold not working eitheir in Dropdown component or flatlistprops

Issue: When I am running code inspection there are several issues reported:

Errors:

Found 4 errors.

When I scroll down and select the dropdown, it also goes down with scroll. Here is the screenshot:

Please note it happens on selecting model(the first dropdown input)
If I don't scroll down it works fine

Hi @hoaphantn7604 , good work on the dropdown!

I have a suggestion to let user to override renderItem and renderLeftIcon instead of using the default (current) component, this will let user to adjust the design of the component according to their needs.

This is what the SelectCountry do currently:

return (
    <Dropdown
      ref={ref}
      {...props}
      renderItem={_renderItem}
      renderLeftIcon={() => {
        if (selectItem?.image) {
          return <Image source={selectItem.image} style={[styles.image, imageStyle]} />;
        } else {
          return null;
        }
      }}
    />
  );

I'll connect this with the PR I made

Should that down arrow in right flip when dropdown is opened?

can you add feature to add props to text for the dropdown? it will be good for adding props like numberOfLines and ellipsizeMode

<Text style={[styles.textItem, placeholderStyle, font()]} {...this.props.selectedTextProps}>
{currentValue && currentValue[labelField] || placeholder}

The module works really good. Only thing I did not find is to disable the options in the dropdown menu or simply disable the menu? Is there a way I can do it with this module?

it's not a bug but I am using your package in my project u all did a great job just need to add onfocus(),onBlur(), methods so if user click on to dropdown then border color change

Hello friend,
Firstly thank you for this repo.
I realized that we can't change styles of dropdown select item menu. See the image below. If there is a way doing this, can you explain to me

Hi @hoaphantn7604,

How can I open the Dropdown list using TouchableOpacity outside Dropdown component? Thank you

Hey @hoaphantn7604 ,

State value gets updated without using any setState function in onChange ,
If I only print the stateValue in onChange function, It prints the updated value.

Here is expo (check logs) : https://snack.expo.dev/@ak_expo/react-native-element-dropdown

Hi, I am having this problem when I want to use it in my project

const {
    selectOptions,
    inputContainerStyle,
    mainContainerStyle,
    inputFont,
    label,
    placeholder,
    placeholderStyle,
    error,
    dropdownValue,
    withSearchBar,
    searchBarPlaceholder,
    listContainerStyle,
    supportText,
    inputSearchStyle,
    onSelect,
  } = props

  return (
    <View style={[styles.dropdownContainer, mainContainerStyle]}>
        <Dropdown
          style={[styles.dropdown, inputContainerStyle]}
          fontFamily={inputFont ? inputFont : 'Rubik-Regular'}
          containerStyle={listContainerStyle}
          data={selectOptions}
          labelField='value'
          valueField='id'
          placeholder={placeholder}
          placeholderStyle={placeholderStyle}
          value={dropdownValue}
          onChange={onSelect}
          search={withSearchBar}
          searchPlaceholder={searchBarPlaceholder}
          inputSearchStyle={[styles.inputSearchStyle, inputSearchStyle]}
          iconColor={color.Neutral5}
          maxHeight={200}
        />
    </View>

It was running fine, but when I ran the app again, the error occurred.

I am using a dropdown for the country data and it contains more than 150 data, without search, it is working fine but with search it is throwing error of " Invariant Violation: scrollToIndex out of range: requested index 101 is
out of 0 to 36 "

import { Dropdown } from 'react-native-element-dropdown';
import { ScrollView, Text, TextInput, View } from 'react-native';

return (

<Text style={[styles.regularText, styles.f15]} numberOfLines={1}>
Country/Region

<Dropdown
style={[styles.dropdown, styles.lightText]}
data={allCountries}
labelField="label"
valueField="label"
placeholder="Select Country"
value={country}
onChange={(item) => {
setcountry(item.label);
}}
renderItem={_renderItem}
selectedTextStyle={[styles.selectedText, styles.mediumText]}
placeholderStyle={[styles.selectedText, styles.mediumText]}
maxHeight={300}
search
autoScroll={true}
searchPlaceholder="Search..."
inputSearchStyle={{ height: 40, fontSize: 13, }}
iconColor={colors.primary}
/>

      {/* <Text style={[styles.regularText, styles.errorTextStyle]}>Error message</Text> */}
    </View>

)

I have used Dropdown. When using search input box the error of Cannot read property 'indexOf' of undefined arises.

Whenever I will scroll to the list at first its works fine but a the second time it threw an error

Hi @hoaphantn7604, I'm not sure if I implemented the flatListProps correctly seems I can't receive the alert even if I change it to console.log. Please see below screenshot
