问题 I am trying to use the 'Stepper' react material-ui component, but I am having difficulty using it in a class fashion, rather than function as they have in their previews. Here is what I have so far, and it does load but with some problems: The text that appears is 'unknown step' meaning that the function 'getStepContent' does not gets called properly Every time I am hitting the 'next' button, it gives me an error saying: 'Cannot read property 'has' of undefined' seems like almost all of my

问题 Does anyone know how to remove the margin from material UI icons!? I want for mobile to remove that margin, which is margin-left: -4px and margin-right: 8px ? Is there anyway to override it with classes?

问题 I am trying to pass a list of values to buttons. On Clicking the buttons a modal with the specifically mapped value should appear but in my case only the last value (3) in my array appears in all modals... How should I fix it ? state = { open: false, stationData : [ { id:1, number:'1' }, { id:2, number:'2' }, { id:3, number:'3' } ], }; handleOpen = () => { this.setState({ open: true }); }; handleClose = () => { this.setState({ open: false }); }; render() { const {stationData} = this.state;

问题 I'm facing an issue, and I searched in Google to find answer with no chance. I have created a React / material Ui library, with a lot of components extended from Material UI. This library belongs to a yarn workspace, together with a main app. The library is built with webpack and babel. In the main app, I'm importing these components and try to apply the global theme, created in the main app, using ThemeProvider. It's seems to work as first sight.

问题 I could not reproduce the problem but I tried to. I have a Material UI element with a child I've added inside it. The icon/child is the X in the corner. The tab/parent is the surrounding box.
