1. Create a new project (Font icons, Q4 2025 latest, Bootstrap)
2. Click on "Project setting".
3. Click on "Metrics".
4. Change:
   1. $kendo-font-size-md: 0.875rem
   2. $kendo-font-size-sm: 0.75rem
   3. $kendo-font-size-xs: 0.625rem
      
      
      
5. Close project settings.
6. Now the project is broken.
   1. Crash in javascript console:
      Uncaught _P: There are errors in SASS and it cannot be compiled to CSS.
      PATCH https://themebuilderapp.telerik.com/api/v1/projects/6928717ab857146bc01d9a2e/variables 500 (Internal Server Error)
      
      
   2. The project cannot be saved:
      
      
7. It is no longer possible to load the project. The same error appears in the console as shown above.
8. If I export the metadata from this broken project from the Dashboard and import it into a new project, that project also breaks. I have attached the metadata.

Please help!

Modern CSS supports nesting.  This would seem to be a good way to cut down on the overall size of the export file.

Are there any plans to update ThemeBuilder to support CSS nesting?

Ex.

Instead of this...

.fk-daterangepicker .k-input-suffix,
.fk-daterangepicker .k-input-prefix {
  cursor: pointer;
  &:hover {
  background-color: var(--kendo-color-primary-subtle-hover);
  }
}

I have to define this set of styles like this...

.fk-daterangepicker .k-input-suffix,
.fk-daterangepicker .k-input-prefix {
  cursor: pointer;
}
.fk-daterangepicker .k-input-suffix:hover,
.fk-daterangepicker .k-input-prefix:hover {
  background-color: var(--kendo-color-primary-subtle-hover);
}

Repeating this pattern over an entire design system adds a lot of extra text...

Hey,

I am working with selfmade tokens imported from Figma to Themebuilder. I would like to edit multiple tokens in Themebuilder. E.g. batch edit all token names at once. Is there a way to do that currently? Or something planed like a multiselect in the settings window for tokens?

Thanks

Alex

Hey,

I want to add an Opacity Token but am only left with the option to write a % value manually.

Can you please add the option to select a token inside of a components Opacity Selection?

Greetings

Alex

Hi there

I noticed that the timeline component isn't available in ThemeBuilder, and I wanted to share that we'd really love to be able to style it through the tool if possible.
