neeto-editor/stories/Walkthroughs/Attachments/constants.js

Lines 5 to 33 in 065c79e

	export const ATTACHMENTS_TABLE_ROWS = [
	["attachments", "An array of the metadata of all the attachments."],
	[
	"onChange",
	"Callback function to be called when the attachments need to be updated as a result of CRUD operations.",
	],
	["endpoint", "Endpoint to upload attachments to."],
	[
	"isIndependent",
	"The default 'Add attachments' button can be hidden by providing a falsy value.",

	[
	"ref",
	"Ref for the Attachments component. This ref needs to be used for accessing the handleUploadAttachment function.",
	],
	[
