The DiscreteSlider widget allows selecting from a discrete list or dictionary of values using a slider. It falls into the broad category of single-value, option-selection widgets that provide a compatible API and include the AutocompleteInput, Select and DiscreteRadioButtonGroup 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.
