Drop-downs provide a developer the ability to add a drop-down menu with specific properties to cells in a workbook. These drop-down menus don't require any extra code other than simply specifying which one to use for the drop-down menu.
SpreadJS has 9 different kinds of drop-downs, and this demo shows how to use the Slider drop-down.
You can use Slider drop-down with the following code :
There are also some option items for customizing the slider:
scaleVisible: boolean : Specify whether the thumb can drag over tick only, default value is false.
max: number : The maximum value the slider can slide to, default value is 100.
min: number : The minimum value the slider can slide to, default value is 0.
step: number : The granularity that the slider can step through values. Must greater than 0, and be divided by (max - min) . When marks no null, step can be null, default value is 1.
tooltipVisible: boolean : If true, tooltip will show always, or it will not show, even if dragging or hovering, default value is false.
width: number : Specify the slider's width when direction is horizontal, default value is 350.
height: number : Specify the slider's height when direction is vertical, default value is 350.
direction: "horizontal" | "vertical" : Specific the direction of slider, default value is horizontal.
marks: number[] : Tick mark of Slider, type has value and label.
formatString: string : Specify the display formatter, that used to tooltip or marks.
showNumberRange: boolean : Specify whether the slider show as select number range mode, default value is false.
