I currently have a search input which filters through the github repos. I then have a drop down select which allows a user to filter based on the language of the code used. I instead would like to use buttons rather than a drop down. Is there a way to filter the results on click as opposed to onChange like I am doing with the drop down. My code is as follows:
const Profile = () => {
const [formData, setFormData] = useState(INITIAL_STATE)
const [updated, setUpdated] = useState(false)
const [created, setCreated] = useState(false)
const { data } = useContext(GithubContext)
const handleUpdated = () => {
setUpdated(!updated)
data &&
data.sort((a, b) => {
if (updated) return a.updated_at > b.updated_at ? -1 : 1
return a.updated_at > b.updated_at ? 1 : -1
})
}
const handleCreated = () => {
setCreated(!created)
data &&
data.sort((a, b) => {
if (created) return a.created_at > b.created_at ? -1 : 1
return a.created_at > b.created_at ? 1 : -1
})
}
const handleInputChange = field => e => {
setFormData({ ...formData, [field]: e.target.value })
}
const classes = useStyles()
return (
<>
<div style={{ marginTop: 85, marginBottom: 85 }}>

export default Profile
and here is the drop down component:
import React, { useRef } from "react"
// MUI stuff
import Select from "#material-ui/core/Select"
import InputLabel from "#material-ui/core/InputLabel"
import MenuItem from "#material-ui/core/MenuItem"
import FormControl from "#material-ui/core/FormControl"
const SelectStatus = ({ language, handleInputChange }) => {
const inputLabel = useRef(null)
return (
<FormControl style={{ width: "100%" }}>
<InputLabel ref={inputLabel} id='demo-simple-select-outlined-label'>
Status
</InputLabel>
<Select
labelId='demo-simple-select-outlined-label'
id='demo-simple-select-outlined'
value={language}
onChange={handleInputChange("language")}
fullWidth
>
<MenuItem value='All'>All</MenuItem>
<MenuItem value='HTML'>HTML</MenuItem>
<MenuItem value='JavaScript'>JavaScript</MenuItem>
<MenuItem value='Ruby'>Ruby</MenuItem>
</Select>
</FormControl>
)
}
export default SelectStatus
Any suggestions would be extremely helpful!!!
You can just use buttons and add them a value so it will work exactly the same as the dropdown
const handleInputChange = field => e => {
setFormData({ ...formData, [field]: e.target.value })
}
<Button onClick={handleInputChange('language')} value="All">All</Button>
<Button onClick={handleInputChange('language')} value="HTML")>HTML</Button>
<Button onClick={handleInputChange('Javascript')} value="Javascript">JavaScript</Button>
<Button onClick={handleInputChange('Ruby')} value="Ruby">Ruby</Button>

I want to add an editable text field in dropdown options of MUI Autocomplete.
I was able to add MUI text field by adding it in renderOption prop of Autocomplete.
Problem
I am not able to edit the text fields since the autocomplete selection overrides it.
<Autocomplete
open={open}
multiple
value={!!value ? [value] : []}
classes={{ popupIndicatorOpen: classes.popupOpen }}
closeIcon={null}
popupIcon={<KeyboardArrowDownIcon style={{ opacity: 0.6 }}/>}
forcePopupIcon
style={{ width: 300 }}
options={options} //array
getOptionLabel={opt => isInstanceOfIRange(opt) ? Concatenate([opt.min.value, opt.max.value], ' - ') : opt.value.toString() || ''}
renderTags={(opts, getTagProps) =>
opts.map((opt, index) => (
<CustomTag key={index.toString()} opt={opt} {...getTagProps({ index })} classes={classes} />)
)}
onChange={handleChange}/
renderInput={params => (
<TextField
{...params}
label={props.label}
variant='filled'
onFocus={() => setOpen(true)}
onInput={onInputChange}
/>
)}
renderOption={(option, { selected }) => (
<CustomOption option={option} selected={selected} />
)}
PopperComponent={PopperComponent}
PaperComponent={PaperComponent}
/>
Custom Options rendering text box
const CustomOption = ({ selected, option }) => (
<div style={{ display: 'flex', flexDirection: 'row' }}>
<Checkbox
size="small"
color="primary"
checked={selected}
style={{ marginRight: 8 }}
icon={<RadioButtonUncheckedIcon />}
checkedIcon={<RadioButtonCheckedIcon />}
/>
{
isInstanceOfIRange(option) ? <RangeRender option={option} /> : <SingleRender
option={option} />
}
</div>
);
The Two text boxes are rendered using this component
const RangeRender = ({ option: { min, max } }) => {
const { labelPostfix, labelPrefix } = useContext(DropDownContext);
const inputProps = labelPrefix ? {
startAdornment: <InputAdornment position="start">{labelPrefix}</InputAdornment>,
} : labelPostfix ? { endAdornment: <InputAdornment position="end">{labelPostfix}
</InputAdornment>,} : {};
return (
<Box style={{ display: 'flex', gap: 12 }}>
<NummberField
type="number"
variant="outlined"
value={min.value}
InputProps={inputProps}
/>
<NummberField
type="number"
variant="outlined"
value={max.value}
InputProps={inputProps}
/>
</Box>);
};
I am trying to hide the grid item of a certain product and let the others slide in. Right now i am using the display:none property but it hides the item instantaneous.

You need to filter the items as you expect by color or size first.
...
const filteredProducts = newItems.filter(newItem => newItem.id === product.id);
...
<Container maxWidth="lg" >
<Grid
container
// You don't need to use direction="row" since it is default props value
spacing={3}
>
{filteredProducts.map((product) => (
<Grid item xs={12} sm={6} md={4} lg={3} key={product.id}>
<Product product={product} disable={newItems.some(newItem => newItem.id === product.id)} />
</Grid>
))}
</Grid>
</Container>
...
If you want to filter the products more accurately, then you could build a customer filter function. Please refer to this.
I'm using Formik with chakra UI to create dynamic forms using the Fomrik Field array. and I Open my form in Chakra modal, problem is when I open my form in modal it change field name and id to array last object id , When i remove modal its works as expected, I Recreated my problem here

as I can see you create modal views for each field. This is not a bad solution but it is better to make one modal and give it data to display (I take out the modal component from the map cycle)
Now the main problem to set special data for each button. I add the state new field id.
In formik inputs change values and names to locations[${modal.id}].facebookUrl
The reason, why are you getting last modal is not controlling it's statement. There is now field which says React not to show 2nd,3nd or other components, so there are 4 modals on each other. You can also use your code but add condition which will hide or show your modal view for example
modal.id === idx && <Modal/>

I have a component that scrolls to view after a comment has been submitted.
const commentSubmit = (e: any, id: number) => {
......
divRef.current.scrollIntoView({ behavior: "smooth" });
};
It scrolls to the comment where <div ref={divRef]></div> is placed which is at the bottom of the most recent comment. The probelem is that if i make a new post, it will scroll into the wrong div element. So its just scrolling at the very bottom. How can i tell ref to scroll to the a specific element based on what post the comment belongs to ?
{post.Comments.length > 0 ? (

The question seems quite complicated, but i over complicated it.
What i had to do was add this
setTimeout(() => {
divRef.current.scrollIntoView({ behavior: "smooth", block: "center", inline: "nearest" });
}, 1500);
in the commentSubmit method, this will scroll to the recent comment.
const commentSubmit = (e: any, id: number) => {
e.preventDefault();
const formData = {
comment_body,
id,
gifUrl,
};
props.postComment(formData);
setCommentBody("");
setOpenForm(false);
console.log(divRef);
// divRef.current.scrollIntoView({ behavior: "smooth" });
// my attempt to scroll to the lastest comment.
setTimeout(() => {
divRef.current.scrollIntoView({ behavior: "smooth", block: "center", inline: "nearest" });
}, 1500);
}
And make some adjustments to the code, if there are no comments divRef will throw an error upon adding a comment, because it is looking for a comment but there aren't any comments, so we will do this if there are comments less than 1 or 2. In my case im using 2 cause im showing 2 comments initially and i have a filter that shows more comments, and show less.
{post.Comments.length === 0 ? <div ref={divRef}></div> : null}
reference scrollIntoView Scrolls just too far
Rest of the code
{post.Comments.length === 0 ? <div ref={divRef}></div> : null}
{post.Comments.length > 0 ? (
<Fragment>
<Typography style={{ padding: "10px 0px", margin: "20px 0px" }}>Commments</Typography>
<CommentList ref={divRef} user={currentUser} deleteComment={props.deleteComment} userId={post.userId} postId={post.id} comments={post.Comments} {...props} />
{/* if show more hide show more button and show show less comments button */}

<Grid item={true} sm={12} lg={12} style={{ padding: "30px 0px" }}>

I am using formik for the forms. In my form, I need to use the concept of FieldArray and it's a nested one. I could not fill the nested forms with respective values. Here is how I have done
const Itinerary = ({ itineraries, push, remove }) => {
return (
<>
<Heading>Itinerary</Heading>
{itineraries && itineraries.length === 0 && (
<span
style={{
color: theme.color.primary,
padding: "0 10px",
cursor: "pointer"
}}
onClick={() => push({})}
>
+
</span>
)}
{itineraries &&
itineraries.length > 0 &&
itineraries.map((day, index) => {
return (
<React.Fragment key={index}>
<Row key={index} style={{ alignItems: "center" }}>
<Text>
How many
<DaysField
component={TextField}
name={`itineraries.${index}.days`}
placeholder="days"
normalize={val => val && parseInt(val)}
/>
of itinerary?
</Text>
{itineraries && itineraries.length - 1 === index && (
<>
<Button>
<Button.Round onClick={() => push({})}>+</Button.Round>
</Button>
<Button>
<Button.Round onClick={() => remove(index)}>
-
</Button.Round>
</Button>
</>
)}
</Row>
<FieldArray
name={`itineraries.${index}.itinerary`}
render={({ push, remove }) => (
<>
<Heading>
Fill up itinerary
{itineraries[index].itinerary &&
itineraries[index].itinerary.length === 0 && (
<span
style={{
color: theme.color.primary,
padding: "0 10px",
cursor: "pointer"
}}
onClick={() => push({})}
>
+
</span>
)}
</Heading>
{itineraries[index].itinerary &&
itineraries[index].itinerary.length > 0 &&
itineraries[index].itinerary.map((i, idx) => {
console.log(
"itinerary index",
itineraries[index].itinerary[idx]
);
return (
<React.Fragment>
<Row
style={{
alignItems: "center",
alignSelf: "center"
}}
>
<Col xs={12} md={3}>
<Field

return value && parseFloat(value);
}}

</Col>
<Col xs={12} md={1}>
{itineraries &&
itineraries.length - 1 === index && (

<ActionBtn>

</>
)}
</Col>
</Row>
</React.Fragment>
);
})}
</>
)}
/>
</React.Fragment>
);
})}
</>
);
};
The itineraries initialValues looks like this
itineraries: [
{
days: 1,
itinerary: [
{
day: "Day 1",
description: "description",
overnight: "overnight info",
altitude: 150.5
},
{
day: "Day 2",
description: "description 2",
overnight: "overnight info",
altitude: 150.5
}
]
}
]
Only Nested part is not working. Can anyone help me at this, please?
You problem is in how you pass the name for the component:
name={`${itineraries[index].itinerary[idx]}.overnight`}
This way, what you are doing is passing the value of itineraries[index].itinerary[idx] to a string.
What you should do is pass that as a string, not it's value:
name={`itineraries[${index}].itinerary[${idx}].overnight`}
This way, only the indexes get the value printed, which is correct.
Here is the difference
${itineraries[index].itinerary[idx].overnight will return [object Object].overnight because you are access the value of itineraries[index].itinerary[idx] and it's calling .toString().
But itineraries[${index}].itinerary[${idx}].overnight will return itineraries[0].itinerary[0].overnight which is a valid formik string and it can get it's value.
