I'm having problems with material UI Autocomplete changing from single select to multiple select based on condition throws error Cannot read property 'length' of null
Here's a codesandbox demonstrating this:
https://codesandbox.io/s/material-demo-forked-q0038?file=/demo.js
Here I have created scenario to change from single to multi conditionally
I know I can use another autocomplete component if it's multi but if there any solution to do in single component it will be helpfull
You can set the key prop to ismulti:
<Autocomplete
multiple={ismulti}
id="tags-standard"
key={ismulti} // here
options={top100Films}
getOptionLabel={(option) => option.title}
renderInput={(params) => (
<TextField
{...params}
variant="outlined"
label="Multiple values"
placeholder="Favorites"
/>
)}
/>

I was using previous Mui version 4.11.4 with the Autocomplete component and everything worked well with the disablePortal prop.
However, i am using Mui 5 now and the autocomplete dropdown list sometimes show on top instead of always being on the bottom as what i wanted.
<Autocomplete
disablePortal={true}
id='controlled-demo'
ref={idRef}
name={id.current}
onChange={(e, value) => {
const id = idRef.current.getAttribute('name');
handleOptionChange(e, value, id);
}}
options={getExercisesByCategoryAndMusclegroup(exercise)}
getOptionLabel={(option) => `${option.title}`}
isOptionEqualToValue={(option, value) => option.title === value.title}
renderInput={(params) => (
<TextField
{...params}
name='exercise'
// onChange={(e, value) => handleOptionChange(e, value)}
label='Search exercise...'
variant='outlined'
size={isMatched ? 'small' : 'medium'}
/>
)}
/>
I've tried using a custom Popper component as i saw on another post setting the placement to 'bottom' but that didnt resolve my issue.
Is there a bug to the new v5? Anyone else is experiencing this?
I don't know if this is a bug in MUI v5, but what worked for me is to simply remove the disablePortal prop, which automatically set the placement of the dropdown list to the bottom for any number of elements in the list.
I'm displaying three property values (option.primary_line, option.city, option.state, and option.zip_code) from state in the autocomplete suggestions; however, I'm trying to display only the option.primary_line value in the textarea when an option from the list is selected. I've tried setting the option.primary_line value to state and adding it as a value (tried defaultValue as well) to the textarea to no avail. What am I missing?
<Autocomplete
id="combo-box-demo"
options={addressSuggestions}
getOptionLabel={(option) =>
`${option.primary_line}, ${option.city}, ${option.state} ${option.zip_code}`
}
onInputChange={handleAddressLookup}
freeSolo={true}
renderInput={(params) => (
<TextField
{...params}
variant="outlined"
fullWidth
/>
)}
/>
You should use renderOption instead, and in getOptionLabel return the value you want to be assigned to the input
<Autocomplete
...
renderOption={(option) =>
`${option.primary_line}, ${option.city}, ${option.state} ${option.zip_code}`
}
getOptionLabel={(option) => option.primary_line}
...
/>
I have a problem using the Autocomplete component provided by Material UI for React.js.
Here is what my component looks like :
<Autocomplete
options={options}
value={value}
disableCloseOnSelect
onChange={handleChange}
limitTags={4}
getOptionLabel={(option) => option.name }
renderOption={(option, { selected }) => (
<React.Fragment>
<Checkbox
icon={icon}
checkedIcon={checkedIcon}
className={classes.checkbox}
checked={selected}
/>
{option.name}
</React.Fragment>
)}
renderInput={(params) => (
<TextField {...params} variant="outlined" label={label} placeholder={label} />
)}
{...custom}
/>
I can't get the feature disableCloseOnSelect to function with a controlled component, as it does not prevent the list from closing after select... If I remove the props value and onChange everything works perfectly, but I need them for my project.
Does anybody have the same problem or see anything wrong with the way I am handling things ?
There is an issue that seems to match mine here. In that case, could it be a bug ?
This is most probably caused by the mother component re-rendering. Autocomplete's state needs to be localised.
Here's a sandbox demonstration of the difference this makes:

It also has performance benefits.
Solution
I used renderTags in my Autocomplete:
renderTags={() => (
<div>
{(props.selectedAutocompleteValues).map(value => (
<Chip key={value} label={value} />
))}
</div>
)}
Original question
I'm trying to add a handler that clears all selected values from an Autocomplete with multiple values and a dropdown. Basicly duplicating the action of the clear-button that is inside the Autocomplete, and triggering this action from outside the Autocomplete.
The reason for this is that I want to have a filter (material-ui Select) that allows reduces the number of options in the Autocomplete. When changing the filter-value, the previously selected values of the Autocomplete should be cleared.
I'm rendering the values in the Autocomplete with the following code, so it seems like what I need to do is change the params in some way. Any suggestions on how to do this, or other ways of clearing the values?
renderInput={params => (
<TextField {...params} label="my-label" variant="outlined" fullWidth />
)}
Update after comment from Ryan Cogswell:
<Autocomplete
multiple
disableCloseOnSelect
autoHighlight
clearText='Nullstill'
closeText='Lukk'
openText='Åpne'
options={Array.from(props.myMap.keys())}
onChange={(event: any, value: string) => {
props.myUpdateFunction(value)
}}
renderInput={params => (
<TextField {...params} label="myLabel" variant="outlined" fullWidth />
)}
/>
where myUpdateFunction is in the grandparent-component of where the Autocomplete is:
myUpdateFunction = (myArray: Array<string>) => {
this.setState({
selectedAutocompleteValues: myArray,
})
}
The Select component that I want to use to reset the Autocomplete component:
<Select
labelId="my-select-label"
id="my-select"
autoWidth
value={props.mySelectValue}
onChange={(event: any) => props.updateSelect(event.target.value)}>
{Array.from(props.selectOptions, ([optionNr, optionName]) =>
<MenuItem key={optionNr} value={optionNr}>{optionName}</MenuItem>
)}
</Select>
with the following onChange handler:
updateFylke = (value: number) => {
const selectedAutocompleteValues = new Array<string>();
this.setState({
mySelectValue: value,
selectedAutocompleteValues: selectedAutocompleteValues,
})
}
I recommend using a controlled input approach (i.e. specify the value prop for the Autocomplete using selectedAutocompleteValues). Then clearing the Autocomplete is just a matter of updating your state appropriately.
You can see an example of this approach in this related answer: Material ui Autocomplete: can tags be created on events aside from 'Enter' events?.
I'm using React and Material-UI framework for a project and want to implement the MUI-Autocomplete Component. I do get the options displaying as they're meant to be but upon selecting one of these options the Input field goes blank and even the state remains unchanged.
I also tried the demo on the website and couldn't get it to work.
Here's the code. Take a look at output here.
Link to video showing output
<Autocomplete
id="combo-box-demo"
options={this.props.products}
getOptionLabel={option => option.name}
style={{ width: 300 }}
renderInput={params => (
<TextField
{...params}
label="Combo box"
variant="outlined"
fullWidth
/>
)}/>
I could not replicate the problem on CodeSandbox but here's the link to it.
