  • Detect and act on when options are changed. (However, class-related options and encrypt are excluded)
  • When options are changed, if keyRandomize is true, the key array is changed randomly.
  • You can bind only one value to one keypad, or you can bind multiple values.
  • You can always keep the value of the show true and adjust the position of the keypad so that the keypad can always be located in a fixed layout.
  • You don't have to always bind the visible value.
  • If you match the total length of the optional keyArray with the total length of the keypad, the design will not break.
  • You can use Slot
 <div>Something you want</div>
