# TreeList Templates

You can customize the TreeList appearance and behavior through the various templates it provides so you can add more details for your users - such as format numbers and dates, show images and so on.

The TreeList component can use templates for:

* [columns (cells)](https://www.telerik.com/blazor-ui/documentation/components/treelist/templates/column) - the rendering of each cell (column). You can, for example, change string formats or add your own components.

* [editing of a cell](https://www.telerik.com/blazor-ui/documentation/components/treelist/templates/editor) - when a cell is in edit mode, it will render this template where you can use custom editors, components and logic.

* [rows](https://www.telerik.com/blazor-ui/documentation/components/treelist/templates/row) - the entire rendering of the `tr` element of the row, so you can fully customize the treelist behavior and rendering.

* [column header](https://www.telerik.com/blazor-ui/documentation/components/treelist/templates/column-header) - the title portion of the column.

* [filter](https://www.telerik.com/blazor-ui/documentation/components/treelist/templates/filter) - the content of the filter cell or filter menu where you can implement custom rendering and logic for the filters.

* [no data available](https://www.telerik.com/blazor-ui/documentation/components/treelist/templates/no-data-template) - when the TreeList Data collection is empty or null, you can customize the content inside.

* [pager](https://www.telerik.com/blazor-ui/documentation/components/treelist/templates/pager) - the template modifies the layout, content, and functionality of the Pager.

Like other Blazor content, most of them can receive a `context` argument that is the type of the model. To use templates, you must bind the treelist to a named model. The filter and header templates are the exception as they are not related to rows and models.

You must make sure to provide valid HTML in the templates.
