TextField inheritance

While not explicitly documented, the props of the MUI TextField component are also available on the MuiFileInput component.

See: https://mui.com/material-ui/api/text-field/

Example

import AttachFileIcon from '@mui/icons-material/AttachFile'
// ...

<MuiFileInput
  size="small"
  variant="outlined"
  disabled
  slotProps={{
    htmlInput: {
      accept: 'video/*'
    },
    input: {
      startAdornment: <AttachFileIcon />
    }
  }}
/>
