Hi Thiraphat.
Thanks for your business. We REALLY appreciate it!
Per ourĀ Scope of Support / Terms, we don’t provide support for integrating with any specific themes.
However, there are some built-in stylings for some of the WordPress default theme like TwentyFifteen and TwentySixteen, just to make the visual side of things look a bit nicer.
In general, though, we know of users successfully running our plugins with popular themes like Genesis, Divi, Avada, and others. Some themes (e.g. Avada) actually bundle our free/core The Events Calendar plugin (not the premium plugins) into their theme download and have in-depth customizations. In such an example, sometimes our support will direct you to the theme’s support instead if the issue is with their customizations.
Long story short, picking a theme is a big decision, but our pluginsĀ should work with any theme built to WordPress’ coding standards / best practices.
Please let me know if you have a specific theme in mind or if there’s anything else I can help with.
Thanks!
