# Viewer type selection

In **PADS4 Designer**, you can select a **specific Viewer Type** when designing a presentation. This helps ensure that you only use elements supported by the selected Viewer. Some Viewer Types may **not support** certain elements—selecting a Viewer Type will **gray out** these unsupported elements to prevent their usage during the design process.

***

## **Why Select a Viewer Type?**

* **Prevent design errors** by only using elements supported by the Viewer.
* Make sure your presentation **runs smoothly** on the target Viewer without compatibility issues.
* Improve **workflow efficiency** by focusing only on available options.

***

## **How to Select a Viewer Type**

1. **Click on the "Presentation" tab** in the ribbon bar.

2. **Go to the "Viewer Type" section.**

3. **Select the desired Viewer Type** from the dropdown list.
   * Example types: Windows Viewer, HTML5 Viewer, Android Viewer, etc.

4. **Save your presentation**:
   * In the **Content Library**, name your presentation and click **Save**.

***

## **What Happens After Selection?**

* **Unsupported elements** for the selected Viewer Type will be **grayed out** in the toolbox and element menus.
* You **won’t be able to add** these elements to your presentation, avoiding future playback issues.
* This helps ensure your presentation is **fully compatible** with the Viewer where it will be displayed.
