问题 I am using Material UI Multiple Select based on documentation example. I need to save id of the selected option and show name, so I render object. When I used example from documentation with placeholder, i see ids instead names of selected. See: https://codesandbox.io/s/kxz5yqmrzv?from-embed const names = [ { id: "a", name: "Oliver Hansen" }, { id: "b", name: "Van Henry" }, { id: "c", name: "April Tucker" }, { id: "d", name: "Ralph Hubbard" }, { id: "e", name: "Omar Alexander" }, { id: "f",

问题 According to the material ui docs here: https://material-ui.com/components/typography/ I should be able to use the Typography component as follows: <Typography variant="h1" component="h1"> Hello World </Typography> However, since updating to nextjs 9, I get this typing error: Type 'string' is not assignable to type 'ElementType<HTMLAttributes<HTMLElement>>' for the component property. I've tried updating the typing dependencies a bunch, but nothing seems to help. Thanks to Shanon's suggestion

问题 I'm using Material-UI and I'd like to use the List/ListItem Component to group my Radio Buttons. Similar to this one: <RadioButtonGroup ...> <List> <ListItem ... nestedItems={[ <RadioButton ... />, <RadioButton ... /> ]} /> <ListItem ... nestedItems={[ <RadioButton ... />, <RadioButton ... /> ]} /> </List> </RadioButtonGroup> Is there a way to archive this? Thanks. 回答1: My temporary workaround is to use checkboxes which look and behave like radio buttons. import List from 'material-ui/lib

问题 The select field can be found here: in the Material-UI demo It's methods appear to be inherited from the menu / popover classes but I haven't been able to figure out how to fire 'open' when onFocus event fires for example. This would solve my keyboard related usability issues! 回答1: You could do it by accessing the DOM node of the down arrow button, and manually triggering a click event on it. Example that works on Mac Chrome on the demo website, via the console, after adding a 'mySelect' id

问题 My Component looks like import React, {PropTypes} from 'react'; import TransactionListRow from './TransactionListRow'; import {Table, TableBody, TableHeader, TableHeaderColumn, TableRow} from 'material-ui/Table'; const TransactionList = ({transactions}) => { return ( <Table> <TableHeader displaySelectAll={false}> <TableRow> <TableHeaderColumn>Name</TableHeaderColumn> <TableHeaderColumn>Amount</TableHeaderColumn> <TableHeaderColumn>Transaction</TableHeaderColumn> <TableHeaderColumn>Category<

问题 I want to display like an error with red color unless there is a selected option. Is there any way to do it. 回答1: For setting a required Select field with Material UI, you can do: class SimpleSelect extends React.Component { state = { selected: null, hasError: false }; handleChange(value) { this.setState({ selected: value }); } handleClick() { this.setState({ hasError: false }); if (!this.state.selected) { this.setState({ hasError: true }); } } render() { const { classes } = this.props; const
