I have been using a Premade React-Bootstrap Typeahead search-bar found here
I am having trouble accessing the child elements from the dropdown. I want to be able to have an Onclick function for the dropdown items, but it doesn't seem like I have access to the children.
Below is the code I have currently, where I use typeahead
<div className="search-bar">
<Typeahead
id="sample"
options= {cities.map((city) => (city))}
labelKey="name"
placeholder="Enter a city"
/>
</div>
How do I get an onclick for these element cities listed?
You can customize menu rendering and behavior by using the renderMenu prop:
<Typeahead
options={options}
renderMenu={(results, menuProps) => (
<Menu {...menuProps}>
{results.map((result, index) => (
<MenuItem
onClick={() => console.log('click!')}
option={result}
position={index}>
{result.label}
</MenuItem>
))}
</Menu>
)}
/>
With the menu items exposed, you're free to add your own onClick handler to each item. Here's a working example.

thanks for being here! My question is related to how I can create an 'onChange' property in the Material UI Menu component. When I am using the 'onChange' property of the Select component, I can easily alter my state after the user clicks on it. I would like to create a similar effect, but then using a Menu instead of a Select component. Note that I am using a function inside a hook, which might complicate things.
Below I could show you how an example of how my code looks:
const [sortingMethod, setSortingMethod] = useState(() => sortHighestSummerTemp);
const onSortMethod = (e) => {
setSortingMethod(e.target.value);
};
<FormControl>
<InputLabel shrink>Sort By </InputLabel>{' '}
<Select defaultValue="" onChange={onSortMethod}>
<MenuItem value={() => sortHighestSummerTemp}>☀️ Hottest summers</MenuItem>
<MenuItem value={() => sortLowestWinterTemp}>🥶 Coldest winters</MenuItem>
<MenuItem value={() => sortMostHotDays}>🥵 Most hot days</MenuItem>
</Select>
</FormControl>;
That's my select component in action, which is working. And here is the same Menu, where I don't know how to implement the "onChange":
<FormControl className={classes.formControl}>
<PopupState variant="popover" popupId="demo-popup-menu">
{(popupState) => (
<React.Fragment>
<Button
variant="contained"
color="primary"
startIcon={<SortIcon />}
{...bindTrigger(popupState)}
>
Sort by
</Button>
<Menu
value=""
// onChange={onSortMethod} <-- How to do this? ⚠
{...bindMenu(popupState)}
>
<MenuItem
onClick={popupState.close}
value={() => sortHighestSummerTemp}
>
☀️ Hottest summers
</MenuItem>
<MenuItem
onClick={popupState.close}
value={() => sortLowestWinterTemp}
>
🥶 Coldest winters
</MenuItem>
<MenuItem onClick={popupState.close} value={() => sortMostHotDays}>
🥵 Most hot days
</MenuItem>
</Menu>
</React.Fragment>
)}
</PopupState>
</FormControl>;
I would be blessed if you could explain how to achieve a similar effect with the Menu component!
Thank you for reading.
I think you should do that per MenuItem (at the onClick property). The Menu itself doesn't have that kind of property: Material-UI page
Secondly, I don't like value as a function. I think you can just pass the variable (sortHighestSummerTemp or sortLowestWinterTemp) to a state. React page reference
This is my JSX:
<FormControl>
<ButtonGroup className="groupedHorizontal">
<InputLabel htmlFor="category">Category:</InputLabel>
<Select onChange={(event) => that.handleCategoryChange(event)} native={true} id="category">
<option></option>
{catOptions}
</Select>
<BrandsPopup />
<Button onClick={(e) => that.removeCategory(e)}>Del</Button>
</ButtonGroup>
</FormControl>
The BrandsPopup is a component which render a material-ui Button within <React.Fragment>. The select and the "Del" button are fine bordered as ButtonGroup elements. The problem is, BrandsPopup is not bordered and does not appear as part of the group. How to apply ButtonGroup styles on the button, rendered from the child component?
ButtonGroup uses cloneElement and thereby assigns its own props to its children. You should be able to log them to the console inside BrandsPopup and then just need to assign them to your button component. It is, of course, possible that this conflicts with how you are using BrandsPopup elsewhere in your app.
And if BrandsPopup indeed only contains one Button component you don't need the Fragment wrapper.
<ButtonGroup className="groupedHorizontal">
<BrandsPopup />
</ButtonGroup>
const BrandsPopup = (props) => (
<React.Fragment>
<Button
// these come from ButtonGroup 🧙
className={props.className}
color={props.color}
variant={props.variant}
>
click me
</Button>
</React.Fragment>
);
I have the following Select from Material UI:
<FormControl className='select-form'>
<InputLabel id="demo-simple-select-outlined-label">Choose User</InputLabel>
<Select
labelId="demo-simple-select-outlined-label"
id="demo-simple-select-outlined"
value={this.state.userId}
onChange={this.handleChange}
label="choose-user"
>
{Object.keys(users).map(uId => (
<div key={uId}className='select-menu'>
<img
src={''}
alt={`Avatar of me`}
className='signin-avatar'
/>
<MenuItem value={30}>{users[uId].name}</MenuItem>
</div>
))}
<MenuItem value={20}>Hello</MenuItem>
</Select>
</FormControl>
My handleChange method gets the value of the MenuItem below with the value of 20 when selected. I just used that as a test and the Select and the onChange work just fine.
The problem is the div, that get dynamically rendered from the users object. I want to render an avatar and the name of the user in every MenuItem. I have to pack them in a div, because the .map() needs to have one parent item.
I want to pass the value (the user id) of the selected MenuItem to the handleChange method, but all I get is an undefined when a user select is clicked.
How can I pass the value of the select to the onChange method, when the Select items are packed inside a div?
The correct way is to put your image inside the MenuItem, and you will get the value
{
Object.keys(users).map((uId) => (
<MenuItem value={uId}>
<img src={''} alt={`Avatar of me`} className="signin-avatar" />
{users[uId].name}
</MenuItem>
));
}
I am using redux form with material ui. I have an array of form templates that are available to select as options. What I am trying to achieve is to get the selected template back, dispatch an action and then initialize redux form with selected template values. I am unable to call the method on SelectItem component (nothing gets logged to the console). I went through the similar problems and solutions but nothing seemed to work in my case. My code goes like this:
setTemplate = (option) => {
console.log(option);}
{formTemplates && (
<Row>
<StyledFormControl>
<Field name="templates" label="Available templates:" component={SelectField}>
<MenuItem value="" disabled>
Choose template:
</MenuItem>
{formTemplates.map(option => {
return (
<MenuItem value={option._id} onClick={this.setTemplate.bind(this, option)} key={option._id}>
{option._id}
</MenuItem>
);
})}
</Field>
</StyledFormControl>
</Row>
)}
Do you have any idea why this should not work? Thanks
try
onClick={() => this.setTemplate(option).bind(this)}
I am trying to determine if SelectField is expanded or not, i.e. if the dropdown and it's MenuItems are visible.
Currently I use roughly following approach:
<SelectField onClick={() => this.setState({ isExpanded: true })} >
<MenuItem primaryText={
<MenuItemContent onHide={() => this.setState({ isExpanded: false })}} />
}>
</SelectField>
and in MenuItemContent I implement
class MenuItemContent extends React.Component {
componentWillUnmount = () => this.props.onHide()
}
This approach has a drawback, that when you click outside the menu, the componentWillUnmount call is not triggered immidiately, but cca after 200ms, despite the MenuItems are no longer visible.
The Select field menu can be expanded by clicking it, and when is expanded, it will hide either when some menu item is clicked, or user clicks outside the menu.
This is how the SelectField looks when is expanded:
And here is collapsed:
For the better handling of SelectField close event you can use property dropDownMenuProps:
/**
* Object that can handle and override any property of component DropDownMenu.
*/
dropDownMenuProps: PropTypes.object,
By using this prop we can pass to DropDownMenu component onClose prop with handler function, which will be fired instantly after DropDownMenu close (caused by ESC, outside click or item select). Unfortunately DropDownMenu component dont provide similar prop to determine the opening so the only way (without
extending the component) is to follow your approach with onClick event handler.
Here is my working test example:
onSelectClose = () => {
console.log("close")
}
onSelectOpen = () => {
console.log("open")
}
render() {
return (
<MuiThemeProvider>
<div className="App">
<SelectField
floatingLabelText="Frequency"
onClick={this.onSelectOpen}
dropDownMenuProps={{
onClose: this.onSelectClose
}}
value={this.state.value}
onChange={this.handleChange}>
<MenuItem value={1} primaryText="Never" />
<MenuItem value={2} primaryText="Every Night" />
<MenuItem value={3} primaryText="Weeknights" />
<MenuItem value={4} primaryText="Weekends" />
<MenuItem value={5} primaryText="Weekly" />
</SelectField>
</div>
</MuiThemeProvider>
);
}
