# Widgets in DataLens On-premises

_Widgets_ are dashboard elements. You can create links between **Selector** and **Chart** widgets.

DataLens supports the following widget types:

* [Chart](#chart)
* [Selector](#selector)
* [Selector (JS)](#js-selector)
* [Text](#text)
* [Title](#title)

## Chart {#chart}

Visualization as a table or chart.
You can place charts anywhere on the dashboard and resize the dashboard.
Charts can be linked to selectors.

For more information about charts, see [DataLens On-premises chart](../concepts/chart/index.md).

## Selector {#selector}

A filter that affects query results on its linked widgets. To add a selector to a dashboard, go to [Adding a selector to a dashboard in DataLens On-premises](../operations/dashboard/add-selector.md).
A selector can be linked to a chart or another selector. For more information, see [Link in DataLens On-premises](./link.md).

For more information about selectors, see [Selectors in DataLens On-premises](./selector.md).


## Text {#text}

Text widget. A text-only dashboard element for links, captions, and other similar content. Supports [Markdown](https://ru.wikipedia.org/wiki/Markdown).
For more information about Markdown markup, see [Markdown in DataLens On-premises](./markdown.md).

## Title {#title}

Heading widget. You can use it to separate similarly themed charts, group them within a single dashboard page, and create a [table of contents](./settings.md#contents) for the dashboard. Only for text data.
