Repeat sections

If your templates use repeat section, you may want to link data between or across multiple sections.

To understand the data involving repeat sections, it's important to understand the structure and concepts of repeat sections to see how they work.

There are 3 key item types:

dynamicfield / Repeat section: This is the repeat section itself.
primeelement: This is the "template" for any items/questions added when adding a new repeat section. This is not visible when conducting inspections.
element: This is an instance of the prime element. This is what you see when conducting inspections.

Consider the following example of repeat sections.

Example of repeat sections

This data appears as follows when exported

item_id	parent_id	type	primeelement_id	primeelement_index	label	response
`aaaa`	`zzzz`	`dynamicfield`			My Repeated Section
`bbbb`	`aaaa`	`primeelement`	`bbbb`
`cccc`	`cccc`	`textsingle`	`cccc`		My Repeated Text
`dddd`	`dddd`	`question`	`dddd`		My Repeated Question
`eeee`	`aaaa`	`element`	`bbbb`	0
`ffff`	`eeee`	`textsingle`	`cccc`	0	My Repeated Text	Text for 1
`gggg`	`eeee`	`question`	`dddd`	0	My Repeated Question	Yes
`hhhh`	`aaaa`	`element`	`bbbb`	1
`iiii`	`hhhh`	`textsingle`	`cccc`	1	My Repeated Text	Text for 2
`jjjj`	`hhhh`	`question`	`dddd`	1	My Repeated Question	No
`kkkk`	a`aaa`	`element`	`bbbb`	2
`llll`	`kkkk`	`textsingle`	`cccc`	2	My Repeated Text	Text for 3
`mmmm`	`kkkk`	`question`	`dddd`	2	My Repeated Question	N/A

As a tree the structure looks like this.

dynamicfield - My Repeated Section (id: aaaa)
├── primeelement (id: bbbb)
│   ├── My Repeated Text (id: cccc)
│   └── My Repeated Question (id: dddd)
├── element (id: eeee, primeelement_id: bbbb)
│   ├── My Repeated Text (id: ffff, primeelement_id: cccc)
│   └── My Repeated Question (id: gggg, primeelement_id: dddd)
├── element (id: hhhh, primeelement_id: bbbb)
│   ├── My Repeated Text (id: iiii, primeelement_id: cccc)
│   └── My Repeated Question (id: jjjj, primeelement_id: dddd)
└── element (id: kkkk, primeelement_id: bbbb)
    ├── My Repeated Text (id: llll, primeelement_id: cccc)
    └── My Repeated Question (id: mmmm, primeelement_id: dddd)

The primeelement_id will always be identical for the same question across different elements/repeat sections.

primeelement_index increments from 0 and is the index of the element in the repeat section. Questions under the same element will have the same index.
