<a id="section_N10021_N1001E_N10001"></a>
Specifies column information about the dynamic columns in a grid.

Use `dynamicColumns` on view and edit pages.

Use `dynamicColumns` with the `cellTemplates[]` in the `grid` tag. All `dynamicColumns` attributes are required except for `id`, which is for debugging purposes.

`dynamicColumns` is a child tag of the `grid` tag. See "Defining Dynamic Columns" in [Concept: grid](/wcp_docs/tgx1652476064414.html).

The values of the `templateId` attribute in the column data must each correspond to the `templateId` of a `cellTemplate` in `cellTemplates[]`.
