# Nesting Repeatable Data

The Table field type may be nested to provide a more advanced way of capturing data.

* * *

So you're [capturing repeatable data](https://help.formsfly.com/en/article/capturing-repeatable-data) and [customizing the output](https://help.formsfly.com/en/article/outputting-repeatable-data). However, specific scenarios require capturing a single set of repeatable fields and a sub-set, i.e., Parent and Child repeat.

This is where nesting a Table field (Child) within another Table (Parent) can achieve this in-app and is supported in custom data templates.

### Use Cases

*(Data Entry Form - Designer)*

Suppose you're a property manager who needs to audit a building containing multiple apartments and rooms in each apartment.

Or repairing equipment on-site with numerous components, each with a sub-set of parts to be recorded.

Or, for any reason, you need to capture a set of repeating data that also need another set of repeats within it.

This is where nesting a Table field within another Table field should come in handy.

When designing your form, add a Table field (parent) and populate it with additional fields, then drag 'n drop another Table field (child) into the parent table, and populate.

### Custom Data Output

Besides our pre-built templates for swift PDF outputs (Classic Grey, App, and Smart Layout), you can fully customize your own templates.

The standard [repeat syntax](https://help.formsfly.com/en/article/outputting-repeatable-data) can be used in custom Word or Excel templates to display repeatable and non-repeatable captured data legibly.

i.e.

{{!REPEATROW}}

{{!REPEATSTART}}

{{!REPEATEND}}

The following example demonstrates a custom Word template using repeat row syntax for parent and child repeats and non-repeatable captured data in a few configurations.

| It isn't necessary to have double "REPEATSTART" or nested "REPEATROW" tags anywhere in your template to output data from your parent and nested child repeats. |

### Limitations

Nested repeats support the following:

-   Maximum of 2 levels (parent repeat > child repeat).
-   Configuration of a Table field (child) within another table (parent) **ONLY**.
-   The child table doesn't support *Populate from a Data Source*.   
    *However, field values inside a table can be dynamically driven using the "Dynamic Value" property by referencing field data names from outside or inside the table to pre-populate them.*
