The MultiSelect 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 CrossSelector, CheckBoxGroup and CheckButtonGroup widgets.

For more information about listening to widget events and laying out widgets refer to the widgets user guide. Alternatively you can learn how to build GUIs by declaring parameters independently of any specific widgets in the param user guide. To express interactivity entirely using Javascript without the need for a Python server take a look at the links user guide.

Parameters:#

For layout and styling related parameters see the customization user guide.

multi_select.value

The MultiSelect widget exposes a number of options which can be changed from both Python and Javascript. Try out the effect of these parameters interactively:
