How to Use the Builder In the WordPress admin sidebar go to Options Builder. Click Add New Panel and fill in the panel name, slug, icon, and position. Add sections and drag fields into rows. Configure each field’s ID, label, type, default value, and options. Click Save Panel — the panel appears immediately as a live admin menu page. Tick the Customizer Integration checkbox to mirror the panel into Appearance → Customize. Bake to PHP The Bake to PHP button exports any builder panel to a standalone PHP file you can commit to your theme. Open any panel in the builder. Click Bake to PHP in the top toolbar. Copy the generated code into your theme’s functions.php or a dedicated options file. The exported file is self-contained and has no dependency on the builder — it uses TPMeta_Options::set_args() and set_section() directly, so it works even if the builder is later deactivated. WordPress Customizer Integration Any option panel (PHP-registered or builder-created) can be mirrored into Appearance → Customize. Enable via PHP 'Theme Options', 'customizer_integration' => true, // ← enables Customizer mirroring ) ); ?> Enable via the Visual Builder Open the panel in the builder, check the Customizer Integration checkbox, and save. Reading Values Values saved through the Customizer and the admin panel use the same storage (theme_mod). Read them identically:
