Hi Jorge,
We are extremely sorry for the long delay.
We have checked your reported query for “Adding mixed themes for components ”. We can add required themes for the individual controls by generating themes from our Theme Studio and add those styles in the application.
We have prepared a sample by achieving your requirements and updated in below link.
Meanwhile, we would like to let you know that we can’t mix the themes for the components which has dependencies to another component. For example, Dialog component is dependency to Grid/Scheduler component. So, we couldn’t render both Dialog and Grid with different themes in a same page.
For more details about Theme Studio, please refer to the below links
Could you please check and confirm whether it meets your requirements?
Regards,
Joshna L
