The IntRangeSlider widget allows selecting an integer range using a slider with two handles.

Discover more on using widgets to add interactivity to your applications in the how-to guides on interactivity. Alternatively, learn how to set up callbacks and (JS-)links between parameters or how to use them as part of declarative UIs with Param.

Parameters:#

For details on other options for customizing the component see the customization guides.

Core#

disabled (boolean): Whether the widget is editable
start (int): The range’s lower bound
end (int): The range’s upper bound
step (int): The interval between values
value (tuple): Tuple of upper and lower bounds of the selected range
value_throttled (tuple): Tuple of upper and lower bounds of the selected range throttled until mouseup

Display#

bar_color (color): Color of the slider bar as a hexadecimal RGB value.
direction (str): Whether the slider should go from left to right (‘ltr’) or right to left (‘rtl’).
format (string): The datetime’s format
label (str): The title of the widget.
marks (boolean | list[dict]): Marks indicate predetermined values to which the user can move the slider. If True the options are shown as marks. If a list, it should contain dicts with ‘value’ and an optional ‘label’ keys.
orientation (Literal["horizonta", "vertical"]): Whether the slider should be displayed in a ‘horizontal’ or ‘vertical’ orientation.
show_value (boolean): Whether to show the widget value as a label or not.
tooltips (boolean | Literal["auto"]): Whether to display tooltips on the slider handle.
track (Literal["normal", "inverted"]): Whether to display ‘normal’ or ‘inverted’.

Styling#

sx (dict): Component level styling API.
theme_config (dict): Theming API.

Aliases#

For compatibility with Panel certain parameters are allowed as aliases:

name: Alias for label

int_range_slider = pmui.IntRangeSlider(
    label='Integer Range Slider',
    start=0, end=10, value=(2, 8), step=2)

int_range_slider

IntRangeSlider.value returns a tuple of integer values that can be read out but cannot be set like other widgets:

int_range_slider.value

(2, 8)

Label#

You may remove the label/ name by not setting it.

pmui.IntRangeSlider()

Show Value#

You may remove the value label by setting show_value=False.

pmui.IntRangeSlider(show_value=False)

Disabled#

The widget can be disabled with disabled=True.

pmui.IntRangeSlider(label='Int Range Slider (disabled)', disabled=True)

Color#

You can specify a color.

pmui.FlexBox(*(
    pmui.IntRangeSlider(label=f'Int Range Slider ({color})', color=color)
    for color in pmui.IntRangeSlider.param.color.objects
))

Sizes#

For smaller slider, use the parameter size="small".

pmui.Row(
    pmui.IntRangeSlider(label='Age Slider', size="small"),
    pmui.IntRangeSlider(label='Age Slider', size="medium"),
)

Custom Marks#

You can have custom marks by providing a rich list to the marks parameter. Note that unlike continuous sliders the value of the marks should be the integer index of the option.

marks = [
  {
    "value": 0,
    "label": '0°C',
  },
  {
    "value": 30,
    "label": '30°C',
  },
  {
    "value": 60,
    "label": '60°C',
  },
  {
    "value": 100,
    "label": '100°C',
  },
]

pmui.IntRangeSlider(marks=marks)

Tooltip always visible#

You can force the thumb label to be always visible with tooltips=True.

pmui.IntRangeSlider(label='Age Slider', tooltips=True, value=(53, 94))

Tracks#

The track can be inverted or removed with track="inverted" and track=False respectively:

pmui.Row(
    pmui.IntRangeSlider(label='Age Slider', value=(53, 94), track=False),
    pmui.IntRangeSlider(label='Age Slider', value=(53, 94), track="inverted")
)

Vertical Sliders#

The orientation of a slider may be “vertical”:

pmui.IntRangeSlider(label='Age Slider', value=(53, 94), orientation="vertical")

Controls#

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

pmui.Row(int_range_slider.api(jslink=True), int_range_slider)
