My question is if I buy the Metronic Angular template, I can only use the designs that already come by default, that is, I won't be able to add those from the HTML version.
Hi,
The Metronic React comes with limited features as advertised Metronic Preview under the "React" demos tab. You can reuse the static HTML markup from the HTML version in the React version since those elements are available via global bundle CSS for all versions.
However most of the HTML version features, such as jquery components, js plugins are not available in the React version.
Regards.
