Custom Theme

You can save all your formatting and functionality changes in a custom theme. This is where you can upload and download themes specifically designed for the date picker.


You can only use themes generated in the date picker to upload.

Switching to the Custom Tab:

  1. Open theme > select Custom tab.

Here, you will see a custom color scheme with green, red, and blue colors.

  1. Open theme> Click on the Edit (✎) icon from the built-in theme.

In this view, the custom tab will show the same colors used in that theme.

Using a Custom Theme:

There are two ways to use a custom theme:

Global level setting:

In global styling, You can modify the fundamental colors and font families simultaneously. This mode remains unaffected by any functionality changes, such as disabling presets or selecting a single-month calendar. The moment you change the colors and font family in any other options, it will trigger the full customization view.

Using global styling helps keep a consistent style guide while allowing for specific changes to colors and fonts. For instance, if the user wants to change the font from "Segoe UI" to "Georgia". It is possible to do it all at once using global styling.

Full customization

The full customization view refers to a theme that is fully customized, with different colors, font families, and functions for all components. This view is ideal if you want to create your own unique style from scratch.

Reset to Default:

After changing the formatting in other options, when the user re-opens the custom theme option, there is a prompt saying,

“New custom theme created based on selections made to fonts, colors, and functions.”

If you have accidentally changed the color and font family and want to switch back to a consistent style, select the “RESET TO DEFAULT” button. This will revert the theme to the last applied theme.
