The **`Data Design`** element is used to design a template with various elements and placeholders. This template can subsequently be populated with real data and dynamically incorporated into your page via [Page Flow](/app-editor/page-flow.md).
The data design element can be positioned anywhere on the page, but it's important to note that as mere templates, they will not be rendered in the [Page Preview](/app-editor/page-editor/page-preview.md) or when accessed by users of your app.
Each instance of the data design element on a page, will create one design template that can be dynamically shown on your page. Additionally, you have the flexibility to replicate the template multiple times, enabling the addition of rows to a table or any other desired repetition as needed.
Within a Data Design, certain elements like [Image](/app-editor/page-editor/built-in-elements/image.md), [Link](/app-editor/page-editor/built-in-elements/link.md) and [Text](/app-editor/page-editor/editing-text.md), allow you to define placeholder fields, whose values can be set from real data.

Look for the **`Dynamic Content`** toggle switch and the **`Field Name`** settings in these elements for defining the placeholder field names.

For example you can add a [Link](/app-editor/page-editor/built-in-elements/link.md) element and set its [URL dynamically](/app-editor/page-editor/built-in-elements/link.md#dynamic-content). Similarly a text element's content can also be set dynamically.
To facilitate template design, certain element placement rules are relaxed. For instance, you can directly drag a [Layout Column](/app-editor/page-editor/built-in-elements/layout-column.md) into the data design element without the requirement of adding a [Layout Row](/app-editor/page-editor/built-in-elements/layout-row.md) element first.

The usage of Data Design element is explained in more detail in [Dynamic Content](/app-editor/dynamic-content.md).
