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 Time Picker.
You can use the Time Picker drop-down with the following code :
There are also some option items for customizing the TimePicker:
max: ITimePickerValue : The maximum value the time picker can display, the value needs the hour, minute and second attributes.
min: ITimePickerValue : The minimum value the time picker can display, the value needs the hour, minute and second attributes.
step: ITimePickerValue : The granularity the time picker can step through values.
formatString: string : Specify the format of the time item.
height: number : Specify the container of the time picker's size.
