Features

  • Select entire blocks, as opposed to individual words or characters.
  • To select an entire block, mouse down outside the text area and then move the cursor into the block. Once it is selected, you'll see a background color.
  • Keep moving down or up to select multiple blocks.
  • Once selected, the available actions are: copy, cut, and delete.
  • Keyboard shortcuts:
    • Cmd+A (Mac) / Ctrl+A (Windows/Linux):
      • First press: Selects the current block
      • Double press: Selects the whole document using block selection
    • Note: This behavior can be disabled by setting handlers.onKeyDown = null when creating the plugin

Add data-plate-selectable to the container or the element you want to start block selection.

Example:

   <PlateContent
    aria-disabled={disabled}
    className={cn(
      editorVariants({
        disabled,
        focusRing,
        focused,
        size,
        variant,
      }),
      className
    )}
    data-plate-selectable
    disableDefaultStyles
    readOnly={disabled ?? readOnly}
    {...props}
    />

Styling

You can style the selection area by adding this class to the container:
