    "The ``FloatInput`` widget allows selecting a floating point value using a spinbox. It behaves like a slider except that lower and upper bounds are optional and a specific value can be entered. Value can be changed using keyboard (up, down, page up, page down), mouse wheel and arrow buttons.\n",

To express interactivity entirely using Javascript without the need for a Python server take a look at the [links user guide](../../user_guide/Param.ipynb).\n",
