# Conditional Rendering

> This page describes custom page support across editions (Free plan, Basic edition, Professional edition, Dedicated edition) and explains conditional rendering, including toggling rendering directly or binding a variable for reactive rendering.

| **Feature** | **Free plan** | **Basic edition** | **Professional edition** | **Dedicated edition** |
| ----------- | ------------- | ----------------- | ------------------------ | --------------------- |
| Custom page | Not supported | Not supported     | Supported                | Supported             |

You can configure conditional rendering for each component.

Toggle rendering on or off directly, or bind a variable for reactive rendering.

**Note: When a condition is configured and the component is not rendered, the component instance retrieved via the API `this.$('fieldId')` is null.**
