Is it possible to display third level children ?

[azamkth]

Example:
{
name: 'Fruits',
id: 0,
children1: [
{
name: 'Apple',
id: 10,
children2: [
{
name: 'Apple something',
id: 60,
},
]
},
{
name: 'Strawberry',
id: 17,
},
],
},

Unforutnately this isn't supported. There may be a way to do it yourself with the upcoming version, which has a bit more flexibility for customization.

Hello!

I managed to do a workaround until a feature with multiple layers of children is avaible.
I copied the source code locally and updated RowItem in FlatList render method:

_renderSubItemFlatList = (
    subItem,
    subKey,
    uniqueKey,
    selectedItems,
    subItemsFlatListProps
) => {
    return <View>
      <RowSubItem
        _toggleSubItem={this._toggleSubItem}
        subItem={subItem}
        highlightedChildren={this.props.highlightedChildren}
        {...this.props}
      />
      {subItem[subKey] && (
        <FlatList
          style={{marginStart: 10}}
          keyExtractor={(i) => `${i[uniqueKey]}`}
          data={subItem[subKey]}
          extraData={selectedItems}
          ItemSeparatorComponent={this._renderSubSeparator}
          renderItem={({ item }) =>
            this._renderSubItemFlatList(
              item,
              subKey,
              uniqueKey,
              selectedItems,
              subItemsFlatListProps
            )
          }
          initialNumToRender={20}
          {...subItemsFlatListProps}
        />
      )}
    </View>;
  };

FlatList in render method

<FlatList
            keyExtractor={(i) => `${i[uniqueKey]}`}
            data={item[subKey]}
            extraData={selectedItems}
            ItemSeparatorComponent={this._renderSubSeparator}
            renderItem={({ item }) =>
              this._renderSubItemFlatList(
                item,
                subKey,
                uniqueKey,
                selectedItems,
                subItemsFlatListProps
              )
            }
            initialNumToRender={20}
            {...subItemsFlatListProps}
          />
