It would be great, that you will add "disableSelectAll" or "hideSelectAll" property to the configurable object: { name: "multipleSelect", type: "select", label: "Select Options", required: true, options: "rpc: //selectOptions ", multiple: true, hideSelectAll: true, default: ["default"], validate: { minItems: 1, maxItems: 400, }, }, The use case is the restriction of users from selecting all options and giving them the opportunity to select only the needed ones. When the user selects all options, we will pay extra money for every request that the user makes. That is why we need to prevent users from selecting all options in 1 click.
