Hi Sumair,
Thanks for contacting Syncfusion support.
We have checked with your requirement. As requested, we prepared a simple sample by adding both EJ1 component (EJ Ribbon) and EJ2 component in Angular 8 application for your reference.
Please, download the sample from the following link.
After extracting the sample, run npm install to install the dependant npm packges in node_modules directory. Then, run ng serve to host the application to check the output.
Please, check out the following links for configuring EJ1 in angular application.
Angular EJ Ribbon:
Please, check out the following links for configuring EJ2 in angular application.
If you need to use same components of EJ 1 and EJ2 in a same angular component. Then, you need to use compatibility styles to avoid style overriding issues. Please, check out the following links to know more about it.
Please, get back to us if you need any further assistance.
Regards,
Shameer Ali Baig S.
