I am new to React, Redux Form and Material. I would like to create a nested drop down selector component that can be dropped in a Redux Form similar to this:
Here is the renderSelectField used to create the select component.
const renderSelectField = ({
input,
label,
meta: { touched, error },
children,
...custom
}) => (
<SelectField
floatingLabelText={label}
errorText={touched && error}
{...input}
onChange={(event, index, value) => input.onChange(value)}
children={children}
{...custom}
/>
);
const MaterialUiForm = (props) => {
const { handleSubmit, pristine, reset, submitting, classes } = props;
return (
<form onSubmit={handleSubmit}>
<div>
<Field
name="favoriteColor"
component={renderSelectField}
label="Favorite Color"
>
<MenuItem value="ff0000" primaryText="Red" />
<MenuItem value="00ff00" primaryText="Green" />
<MenuItem value="0000ff" primaryText="Blue" />
</Field>
</div>
<div>
<Field
id='chapter'
name='chapter'
component={SelectMenu}
label='Chapter'
/>
</div>
<div>
<button type="submit" disabled={pristine || submitting}>
Submit
</button>
<button type="button" disabled={pristine || submitting} onClick={reset}>
Clear Values
</button>
</div>
</form>
);
};
My SelectMenu component is
const chapterFormValues = [
{
key: "international-4",
caption: "France"
},
{
key: "international-5",
caption: "Africa"
},
{
key: "international-6",
caption: "United Kingdom"
},
{
key: "usa-key",
caption: "North America",
subMenuItems: [
{
key: "usaChapter-1",
caption: "Central"
},
{
key: "usaChapter-2",
caption: "East"
}
]
}
];
const SelectMenu = (props) => {
const [open, setOpen] = useState(false);
const handleClick = () => {
setOpen((open) => !open);
};
const handleSubMenuClose = () => {
setOpen((open) => !open);
};
const { label, classes } = props;
const renderMenuItems = () => {
return (
chapterFormValues !== undefined &&
chapterFormValues.map((option) => {
if (option.hasOwnProperty("subMenuItems")) {
return (
<React.Fragment>
<MenuItem onClick={handleClick} className={classes.menuItem}>
{option.caption}
{open ? <IconExpandLess /> : <IconExpandMore />}
</MenuItem>
<Collapse in={open} timeout="auto" unmountOnExit>
<hr />
{option.subMenuItems.map((item) => (
<MenuItem
key={item.key}
className={classes.subMenuItem}
onClick={handleSubMenuClose}
>
{item.caption}
</MenuItem>
))}
</Collapse>
</React.Fragment>
);
}
return (
<MenuItem
className={classes.menuItem}
key={option.key}
value={option.caption === "None" ? "" : option.caption}
>
{option.caption}
</MenuItem>
);
})
);
};
return (
<FormControl>
<InputLabel>{label}</InputLabel>
<MuiSelect
input={<Input id={`${props.id}-select`} />}
value={props.value}
{...props.input}
{...props.custom}
>
{renderMenuItems()}
</MuiSelect>
</FormControl>
);
};
Here is a link to the code sandbox I created. Material UI ReduxForm Select
It works except the nested drop down does not update the selector field. I have researched this and found this issue Stackoverflow redux form with nested lists but no solution.
Can anyone give me advice as to what I am missing? I believe I need to pass the event in the handleSubMenuClose function back to the Redux Form somehow but am stumped as to how to do this.
