## Understanding Slots

Slots are only **available on LWR Sites**.
{% endhint %}

Slots are a fundamental feature in many Avonni Components for Salesforce Experience Site, playing a crucial role in customizing and enhancing their flexibility. They are essentially placeholders within a component where you can insert various other elements or components, providing a powerful way to tailor the functionality and design of your site’s elements.

## Data Model Sharing with Avonni Components

### Adherence to Salesforce Data Sharing Rules

* **Respecting Org Settings:** Avonni Components fully comply with your Salesforce organization's existing data-sharing configurations and access settings.
* **No Interference Policy:** These components do not alter or affect your pre-established data-sharing rules in any way.
* **Controlled Visibility and Access:** The ability to view and interact with records through Avonni Components is governed by your organization's defined sharing settings and user permissions.

## Advanced visibility control

The pre-built Experience Site Components follow Salesforce's standard visibility model: you can use Audiences to show or hide components based on profile, location, or other broad criteria.

If you need more granular control — showing a component only when a specific field equals a value, or toggling visibility based on a user action — [Avonni Dynamic Components](/dynamic-components/welcome.md) offer a built-in [visibility rule system](/dynamic-components/core-concepts/component-visibility.md) that works on Experience Cloud sites. You can embed Flows, custom LWCs, and Avonni components within a Dynamic Component and manage their visibility from a single place, using conditions based on record data, variables, formulas, or device type.

Dynamic Components and pre-built Experience Components can coexist on the same site page. Use pre-built components when their default behavior is enough, and Dynamic Components when you need conditional logic or complex layouts

## Expressions

Expressions in component configuration dynamically compute values and update content, enhancing site interactivity and responsiveness.
