MultiSelection usage

[caghetti]

Hi,

in the documentation the tree mode supports MultiSelection.
If I understand good the multiselection, it means I can select several elements of my json tree.
I added selection: 'MultiSelection', in my declaration but I have this js error

index.js:1 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length')

Did I understood badly the MultiSelection implementation ?

You can indeed select a range of multiple items using MultiSelection, you can find the type definition here:

svelte-jsoneditor/src/lib/types.ts

Lines 70 to 74 in 2699b71

	export interface MultiSelection {
	type: SelectionType.multi
	anchorPath: JSONPath
	focusPath: JSONPath
	}

For example:

selection: {
  type: SelectionType .multi,
  anchorPath: ['myArray', 2],
  focusPath: ['myArray', 7],
}

To get examples, create your editor with an onSelect that logs the actual selection in the developer console, and then manually select multiple items in the editor to see what the selection object becomes.

Thanks for your reply.
Unfortunately, it's not the the feature I thought about.
I will describe the feature I thought : I want user could select several items via a ctrl+clic
Today I saw you can select several lines via shift + clic but my is, as in the file attached, to select only label, startdate and cug

do you think it could be a feature in a next release ?

Ah, I understand what you mean.

Currently you can indeed only select a single range with multiple items. It is not possible to select multiple individual items. It would be nice to implement support it though.

An I forgot to say : your jsoneditor is very incredible : thanks for this editor !
