Checkboxes instead of radiobuttons in the List component

[walldenfilippa]

Description

List component today

The List component with radiobuttons has one or more datamodelbindings that stores the values in selected columns.

 "dataModelBindings": {
        "name": "SelectedItem",
        "profession": "SelectedItemProfession"
    },

New proposition

If we implement a property in the List component where developers can select radiobuttons (default) or checkboxes, we have to change the formatting of the datamodelbindings. Should the checkbox values be stored in an array of strings or objects? Here is an example of what it could look like using an object array with two attributes in the json file:

 "dataModelBindings": {
          "row": "rowId" {
              "column1": "column1",
              "column2": "column2"
               ...
          }
  }

Is this something that is supported by backend today?

TEMPORARY workaround

Within the repeating group

What we want to accomplish

Additional Information

Requirments

• It is essential that the component supports a large number of data from an external API. (We want to visualize up to 1000 different appOptions). The List component fulfill this requirement.
• One row can hold one or more columns, where each column can be set to a datamodelbinding attribute.
• The selected rows in the List component should be automatically or by logic (in dataprocessor) visualized in another component. (We currently visualize this data in a repeating group)

Additionally (can be done through workarounds without any additional functions)
The external API fetches data to the List component based on an input "search" field. If a user decides to search on a new word in the input field the options in the list component should be exchanged. If the user has selected rows in the previous appOptions list, they should still be displayed in the visualization component (in our case the repeating group).
