    "The ``MultiChoice`` widget allows selecting multiple values from a list of options. It falls into the broad category of multi-value, option-selection widgets that provide a compatible API and include the [``MultiSelect``](MultiSelect.ipynb), [``CrossSelector``](CrossSelector.ipynb), [``CheckBoxGroup``](CheckBoxGroup.ipynb) and [``CheckButtonGroup``](CheckButtonGroup.ipynb) widgets. The ``MultiChoice`` widget provides a much more compact UI than [``MultiSelect``](MultiSelect.ipynb).\n",

Alternatively you can learn how to build GUIs by declaring parameters independently of any specific widgets in the [param user guide](../../user_guide/Param.ipynb). 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",
