Other fields

Select a color​

New in v14.0.0

The ColorField enables a user to select a color from a color palette.

import viktor as vkt


class Parametrization(vkt.Parametrization):
    color = vkt.ColorField('Pick a color')

The value is returned in the params as a Color object.

Select a date​

The DateField enables a user to select a date on a calendar.

import viktor as vkt


class Parametrization(vkt.Parametrization):
    date = vkt.DateField('Pick a date')

The value is returned in the params as a datetime.date object.

Toggle button​

The BooleanField acts as a toggle button which can be either True or False:

import viktor as vkt


class Parametrization(vkt.Parametrization):
    is_true = vkt.BooleanField('False / True')

Generic JSON data​

The purpose of the HiddenField is to store JSON-type data in the params, without showing this information to the user in the editor. For example, when doing upload file processing.

import viktor as vkt


class Parametrization(vkt.Parametrization):
    json_data = vkt.HiddenField('This is not visible')
caution

Use the HiddenField with moderation. Prefer to store specific type of data on its corresponding field (e.g. number on a NumberField), if necessary with visible=False to hide if from the user. Also, prevent storing very large amounts of data if not necessary, as this might make your application slow and unstable!

Manual line break​

For more information on how to add a manual line break to the parametrization, see LineBreak. There is no value associated with a LineBreak within the params.
