Kimai uses the AdminLTE theme which can be configured in the file config/packages/admin_lte.yaml. You find the theme specific documentation here.

All Kimai specific theme settings will be available in the twig templates with the global kimai_context key, e.g.

{{ kimai_context.select_type }}

Default theme color

The default theme colors can be changed to one of the following choices:

  • skin-blue
  • skin-blue-light
  • skin-yellow
  • skin-yellow-light
  • skin-green
  • skin-green-light
  • skin-purple
  • skin-purple-light
  • skin-red
  • skin-red-light
  • skin-black
  • skin-black-light

Add this to your local.yaml.

        skin: skin-blue-light

Please note: unless you change the permissions, users can still change the theme color to their wish. It is recommended to leave the choice to the user, as colors and contrasts are not only a matter of personal choice but might also be necessary for people with visual impairments.

Searchable input types

The select boxes for customer, project and activity are by default the OS standard UI elements. This might be a limit for users with a long list of active and non-hidden elements.

Therefor a test is currently running, which can be activated setting the the following configuration:

        select_type: selectpicker

This will turn the select boxes into javascript elements with quick search option.

Why is this a beta test? It’s not clear, if we keep on using this javascript library or activate it by default. Therefor your feedback is highly welcome, please post your opinion at GitHub.

Active entries warning

A small colored warning sign will be shown, if a user has more than X active timesheet entries.

The amount X is configured in your local.yaml with the setting timesheet.active_entries.soft_limit (see
