Definition
Below is an example of how a group-list field could be defined in a JSON form.
For example, if we had a list of authors in a JSON file:
{
"authors": [
{
"name": "Alice Walker",
"id": "alice-walker",
"best-novel": "The Color Purple"
},
{
"name": "Margaret Atwood",
"id": "margaret-atwood",
"best-novel": "Oyrx and Crake"
},
{
"name": "Isabel Allende",
"id": "isabel-allende",
"best-novel": "Daughter of Fortune"
}
]
}Our group-list field config would look like this:
const formOptions = {
fields: [
{
label: 'Authors List',
name: 'rawJson.authors',
component: 'group-list',
description: 'Authors List',
itemProps: item => ({
key: item.id,
label: item.name,
}),
defaultItem: () => ({
name: 'New Author',
id: Math.random()
.toString(36)
.substr(2, 9),
}),
fields: [
{
label: 'Name',
name: 'name',
component: 'text',
},
{
label: 'Best Novel',
name: 'best-novel',
component: 'text',
},
],
},
//...
],
}
