Overview

An AppBoard Theme is a collection of settings that manage the overall visual presentation of the application to the end-user in the web browser. Elements included in a Theme include colors, button styles, shadows, borders, backgrounds, and so on.

The theme engine is extremely flexible and capable of a wide variety of styles as shown through the default themes shipped with the product. Custom themes can be created by extending the base themes to match the style and look for your organization or group.

Base Themes

AppBoard Themes

AppBoard ships with a number of base themes as shown above (left-to-right): Dark, Flat, Frosted Glass, Light, Minimalist, and Smoked Glass. Please note the base themes are not editable and are shown with a lock icon in the Theme Manager. See the Managing Themes section for more information on how to build custom themes based on the base themes shipped with AppBoard.

Managing Themes

Theme Manager administration page

Perform the following to manage Themes:

1. Log in to AppBoard Builder as an administrator.
2. In the Builder Modes panel, select System Administration, then select Theme Manager. This will launch the Theme Manager panel.

To activate a theme, select a theme from the list of available themes, and click the "Activate Theme" option in the bottom toolbar. The checked theme indicates the currently active theme.

After changing or modifying themes, a browser refresh should be performed to ensure all theme changes are applied.

Creating a New Custom Theme

Perform the following steps to create a new Theme:

1. Click "Add" in the bottom toolbar. This will launch the "Theme Editor".
2. Enter a name for the new Theme to be created.
3. Click "Add Theme".
4. The Theme is created with a set of default settings.
5. Modify the Theme as desired, and then click "Save Changes" to save the changes to the Theme.
6. Apply the theme to the system, if desired, by clicking "Activate Theme" in the bottom toolbar.

If you manually set backgrounds to be dark while using the light theme, then some of the default dark text colors will become unreadable. The best practice is to switch to the "Dark" template if you want a dark look and feel. Doing so will ensure default text colors are readable.

Deleting a Theme

Perform the following steps to delete a Theme:

1. Select the Theme from the list of available Themes.
2. Click "Delete" in the bottom toolbar.

You can only delete custom themes. You can not delete the base themes that ship with AppBoard. You also can not delete a Theme while it is the currently active Theme. In such case, activate another Theme first, and then delete the Theme.

Editing a Theme

Perform the following steps to edit the settings for a Theme:

1. Select the Theme from the list of available Themes.
2. Click "Edit" in the bottom toolbar. This will launch the "Theme Editor".
3. Modify the Theme as desired, and then click "Save Changes" to save the changes to the Theme.
4. Apply the Theme to the system, if desired, by clicking "Activate Theme" in the bottom toolbar.

You can only edit custom themes. You can not edit the base themes that ship with AppBoard.

Using the Theme Editor

An AppBoard theme is a collection of overrides for a default set of attributes. Rather than build up a Theme from scratch, AppBoard Themes start with default values pre-populated from a template. AppBoard ships with a number of base themes to provide a range of starting points.

To get started, select a Theme Template using the pull-down selector at the top of Theme Editor. The base template is all that is required for a Theme. A new Theme without any overrides is basically just a copy of the Theme Template.

By selecting a different Theme Template, you will swap out the base values used by the current Theme. Any overrides configured as part of your new Theme will persist; however, the values used in your overrides may no longer make sense after you have switched from a "Dark" theme to a "Light" theme.

Sample View of the AppBoard Theme Editor

Attribute Overrides

Theme-able elements are organized into categories, which can be selected using the list on the left side of Theme Editor.

Each attribute has a default value that it inherits from its template. To provide an override for that value, check the check box next to the desired attribute. If you decide you do not like the new values you entered, uncheck the checkbox next to the attribute, and the theme will return to its default value.

Details on certain options for attribute overrides are available in the theme configuration detail page.

After changing or modifying themes, in most cases a browser refresh is required to see the Theme changes take effect.

Migrating Custom Themes

Themes consist of two parts:

1. Theme Configuration
2. Theme Assets: logo graphics, background images, etc..

By default any theme configuration is automatically backed up when performing a full backup. For other theme assets on the filesystem then these should be added to the custom export list to ensure the files are included in archives. See the Customizing the Export section of the Backup & Recovery page for more information.

To migrate a custom theme to another AppBoard instance altogether then the Import/Export tool can be used, but please note this only includes theme configuration and the theme assets will have to be copied separately. Refer to the Import/Export documentation for more information. It's also important to include any themes which the exported theme may be dependent on, if not directly dependent on a base theme.
